Review: SDG Tellis V2 Dropper Post - No Slop, More Drop

Apr 9, 2024

SDG Tellis V2

Dropper posts could be argued as one of the most revolutionary changes made to mountain bikes. Nowadays, they're longer, more reliable, and even light enough to become standard equipment on cross-country bikes.

SDG's new Tellis V2 touts an increased size range, with up to 230mm of drop available, plus a new style of clamping saddle rails. Arguably, the standout feature of the post is the patent-pending head, which lowers the stack height by 10mm and makes saddle installation a breeze.
SDG Tellis V2 Details

• Hybrid PTFE & copper keyways
• Lower stack height w/patent pending head
• 30.9, 31.6, 34.9mm diameters
• 75-230mm travel (reduceable in 5, 10, 20mm increments)
• Stanchion diameter: 26mm
• Weight: 609g - 31.6x170mm
• Price:$199.99-224.99 USD
• More info:

SDG’s Tellis V1 Post has treated me well on various test bikes, but the V2’s performance and workmanship is said to have improved, thanks to numerous small but critical details. SDG say that the $199 USD Tellis V2 is smoother and more rigid thanks to a larger stanchion diameter and redesigned keyways, so we put some solid time on the updated version.

The angled clamping bolts make seat installation a breeze.

Construction and Features

The new post head design features an independent saddle rail clamp with hardware that is easily accessible from the side. These clamps also allow for an infinite saddle angle adjustment (within a useful range) and are compatible with 7mm round saddle rails or 7 x 9mm oval rails.

In addition to the 10mm of stack taken off the top of the clamp head, 5mm has been shaved off the bottom of the post, thanks to a redesigned actuator. Conveniently, the cable head still connects to the actuator for speedy installs.

Three diameters of 30.9, 31.6, 34.9mm are available in 75, 100, 125, and 150mm travel configurations as well as the 170, 200, and 230mm options which have 30mm size gaps instead of 25mm. The longest travel 230 post is only available in 31.6 and 34.9 diameters and 26mm stachion diameter are used throughout. Each set post height is adjustable in travel by 5, 10, or 20mm due to the simple split bushing design, excluding the shortest post, which is limited to a 55mm total drop.

The key to that quick travel adjustment is the updated split bushing design from IGUS. There’s also a Trelleborg main seal, which caps off the quadruple sealing system.

The V2 continues to use the Wintek cartridge and is compatible with the current Tellis dropper lever, where SRAM Matchmaker, Shimano, I-Spec EV, and 22.2 bar mounts are available

The price seems less, but it no longer includes the lever, cable or housing.

Price and Weight

Between the various diameters and travel lengths, the price of the Tellis V2 dropper ranges from $199.99 to $224.99USD, which doesn’t include the lever or cable.

On my scale, the SDG Tellis V2 post (31.6x170mm) weighs 609g with the rail clamping hardware, but excluding the cable or lever.

Like any cable activated dropper post, finding the correct length of housing to use is always a bit of a guessing game, but once that is sorted, snugging up, any cable tension is straightforward.

By connecting the cable barb at the actuator, you are free to secure the housing to the post, insert that into the frame and maintain tension on the cable while clamping it in place on the lever. This is much easier than guesstimating and pinching the snipped end of a cable to the tiny hardware at the bottom of the seat post that's found on some other brands. I’ve also found that levers that clamp the cable have less of a tendency to fray the end as well, meaning you can reuse the cable without any issues.

It's worth mentioning again just how easy it is to install a seat on the Tellis thanks to the orientation of the bolts - there's much more room for a tool compared to the traditional mounting style, and it's one of those designs that makes you wonder why everyone doesn't do it this way.

SDG Tellis V2


Is there a noticeable difference between the Tellis V1 and V2 on the trail? I had the chance to ride them both back to back, as the V1 arrived on a test bike. Without a doubt the V2 is smoother and, most importantly, quieter when descending.

One of the first things I noticed was the reduced noise or chatter on the V2, which is due to the copper/PTFE keyways. Before, rattles from the post head could resonate through the bike and fault an otherwise calm bike.

Secondly, there’s smoother actuation as the stanchion glides very seamlessly. Even after riding through sloppy winter conditions for a few months, the Tellis V2 still feels silky smooth. Should something go sideways, SDG does have a gamut of replacement parts available through their dealer networks.

I’ll admit, I did expect the new head clamp design to possibly slip under heavy loading. After clamping the bolts down to the recommended torque and a few seat bounces, there were no signs of slippage. They also avoided emitting any creeks or squeaks, despite the splashy conditions.

OneUp V3 Dropper

How Does It Compare?

Drawing comparisons between another previously released post, the OneUp V3 Dropper, the critical areas that most riders look at when choosing a dropper post is the insertion depth. Measuring from the bottom of the collar to the end of the actuator (the portion that sits inside the frame) the OneUp V3 is 22.5mm shorter, and has a 6mm lower stack height, when comparing them both set to 170mm (OneUp 180 shimmed down 10cm). OneUp's V3 Dropper still has the longest dropper post on the market at a whopping 240mm, 10mm more than the Tellis V2.

Weight wise, the Tellis V2 is in the respectable ballpark, but the OneUp V3 does chop off about 130g. At $55 less, though ($214.99 USD - SDG Tellis V2 vs. $269 - OneUp V3), weight may not be a factor for those looking to save a few bucks. On the warranty side, SDG offers a lifetime guarantee, whereas OneUp’s V3 post comes with a two-year warranty.

Both posts use an actuator that holds the barbed end of the cable and feature ergonomic levers. OneUp’s option features a rubber thumb pad with colorized options. The SDG has a lighter action but the longer lever means pushing further to open the actuator. Each dropper features a black stanchion and body with discrete logos.

Service and Durability

I’ve been ragging on the Tellis V2 for more than six months, where it spent the most time aboard the Devinci E-Troy LTD smashing through winter slop. I’d also wager that seat posts on E-bikes are put through higher loads too since you can pedal across trail undulations faster, therefore leveraging the saddle more.

When I pulled the post apart for an inspection, everything looked fairly clean, but one of the additional seals that’s part of their quad seal system seemed to have some material removed from it. SDG admitted that this particular post may have been rushed out to provide us enough time to put adequate miles on it and recognizes that the additional seal may have been damaged when removing the collar. They're confident that mass production won't see this issue as the same seal system has been working flawlessly for four years in their V1 post.

Despite that minor quibble, no streaks were left on the post or excess grease was pumped out of there during operation and otherwise, the Tellis V2 has remained quiet, smooth and consistent over the test period.

Changing the travel requires unthreading the lock ring collar by hand, sliding the bushing up and clipping the travel limiting spacer onto the post, much like other posts with adjustability. SDG recommends arranging that so that the split points anywhere except at the rear wheel (6-o'clock orientation). That procedure is straightforward to tackle, even for the greenest mechanics. No special tools are required to refresh the internals or adjust the travel either.


+ Side-loading clamps allow for very easy saddle install and removal
+ Smooth operation with virtually no side-to-side play
+ Excellent performance to price ratio


- There are still other posts that offer more insertion depth with less stack height
- Not exactly heavy, but there are lighter options out there

Pinkbike's Take

bigquotesIt's tough to nail all aspects of what consumers demand in a dropper seat post: lots of travel with increased insertion interruption, smooth operation, rattle-free keyways, and it has to be cheap and lightweight too.

SDG has increased the performance of the Tellis V2 dropper considerably with the combination of slick materials used in conjunction with the improved keyways. They've eliminated the annoying rattle found in some dropper posts while keeping the movement extremely smooth. With an attractive price and the convenience of the easy saddle loading, the minor weight gain over the V1 can be shrugged off.

 Orbea, YT and others use rebranded SDG Tellis posts. People don't realise this and take them off their new bikes to "upgrade", which means there's usually bargains to be had on FB market place etc. I picked up a brand new Orbea branded Tellis last year for £27! The guy I bought it off said he had removed it to "upgrade to an SDG Tellis"!!! hahaha
  • 9 11
 I got curious and tore an sdg post apart, went as far as drilling the cartridge out to see how it all works. These posts are just office chairs, there's nothing to upgrade.

 @Tmackstab: the cartridge is dead simple but if you think the V1 post is essentially an office chair, we have some ocean front property in Arizona to sell you. There's a ton of small details that go into a product to substantially elevate the offering so that's what you'll find in the V1 and now in the V2.

With the Tellis V1 we had no experience with droppers so we worked with a select few OEM partners to source a high end dropper vendor and picked their most reliable components. We then elevated that further with a slew of improvements including IGUS Bushings, Trelleborg Seals and a Quad Seal System. The V2 takes these same features, but further elevates it with a laundry list of improvements and brought the price down along with added a lifetime warranty.

 Ha, stoked you got a deal! FYI, every single YT Postman and Postman V2 post is a private labeled Tellis and Tellis V2. YT loves the post so much that they trust us with all their spec and YT has been an incredible partner for us in helping us to constantly refine and improve on the post.

Orbea uses a post that is similar to ours (and a great OEM product), but we do not private label theirs. Our post will have several improvements over that one including an IGUS Bushing, Trelleborg Seal and Quad Seal design. However, for 27 quid you can't beat it!

 @SDG-COMPONENTS: I guess I worded that wrong, I was insinuating that its impressive that you could improve on something so simple. FWIW I've been rocking my SDG post for 3 years now no issues.

 @Tmackstab: Ha, that makes more sense! Yeah, we love the K.I.S.S. principle so focus on improving it where it makes sense (like the new head design, larger diameter stanchion, new keyays and actuator) but keep the things that are proven and work so well (cartridge, Trelleborg seal, IGUS bushing and Quad seal design).

 Damn. I’ve loved my 200mm Tellis for the last year but wanted something with a bit more travel. Can’t wait to try the 230mm with the lower stack and new head design. My Tellis always just works. It’s all I want out of a dropper.
  • 6 1
 Stoked to hear you've been loving the V1! It's worth noting that on the 200mm, it looses an additional 10mm of overall height compared to the V1. With the larger 26mm stanchion we could decrease bushing overlap on the 200mm and so the lower tube was able to loose 10mm of height. Hope you get a chance to get on the V2!

 It’s great there are so many affordable and reliable droppers these days. The SDG sounds like a good addition. But I can’t go past Bike Yoke. I changed back from a one up to a Bike Yoke Devine recently because it’s just that 10% better in terms of build and function.

Absolutely 0 rotational play, never loses pressure, can store it compressed or pick it up by the seat when compressed. Never a drama and always working like clockwork. I’m sure others have a different experience but that’s mine…
  • 9 2
 I've had OneUp, SDG, Fox PNW and other OEM droppers. Nothing has come close to the performance of Bike Yoke. SDG was probably the sloppiest post I've run. Lots of rotation and play.
  • 11 1
 They make a great product and we can't fault them. The Tellis cartridge has less than a 0.1% failure rate in the last 6 years it's been in market which is astonishingly low compared to anyone else. Furthermore, servicing it is dead simple and you can disassemble and rebuild the post in under 10 minutes with basic tools. It's also priced at $199.99 with a lifetime warranty so is over 25% more affordable than the Divine.

 @SDG-COMPONENTS: Hopefully the new model has better tolerances. The rock and rotation was just too annoying for me. BTW, I love the Bel-Air 3.0. All my bikes have one. It's an awesome saddle.
  • 6 0
 @Tinshield: Sorry to hear you had issues. The polycarbonate keyways we use on the V1 are great for super tight tolerances so out of the box and over time the head will have less play than a copper or brass keyway. However, the trade off is that they are easier to sheer from a rotational impact. The V2 features an improved polycarbonate keyway shape and adds copper keyways as well so you get the best of both worlds. Hope you get a chance to check out the V2 and stoked you're loving the Bel-Air V3!

 >>Weight wise, the Tellis V2 is in the respectable ballpark, but the OneUp V3 does chop off a hefty amount of bulk; 229g to be exact.
No way is that accurate, a one-up post does not weigh 380g (609-229).
  • 2 0
 Yes- what about that math?! In some diameters the Tellis is actually lighter than the oneup.
  • 16 1
 @chrsei: OneUp did do an incredible job on the V3 of shaving off a substantial chunk of weight, but definitely not 200+ grams off of the V2. We kept our weight within reason, but honestly weight wasn't really a focus of ours. We stuck to making it the most durable post on the market and the most simple to service. Some people are definitely looking to shave weight, but we built a post that you can forget is there after it's installed since it just simply works.

We brought in a 34.9x180mm OneUp V3 to test against ours and theirs weighs 565g to our 590g so on the 34.9mm we're definitely within reach.
  • 3 0
 Probably worth checking and correcting that weight comparison @mattbeer - I wonder if you meant to type 29g?
  • 11 2
 Been on the 230mm Tellis V2 for a long time now. It is a proper fit and forget post and it has handled the crappy UK riding conditions very well. I cant say the same about the Oneup 240 i had for a shorter amount of time…
No issues even at my sky high saddle height and near 100kg weight. Honestly can’t see a reason why i would use anything else.
Pair it up with a Bel Air 3.0 saddle and you can’t go wrong with that setup, whilst supporting one of the best OG core mtb brands on the scene.
  • 6 1
 Same here. Having been on Fox, X-Fusion, BX, and PNW on various bikes... the v1 Tellis is still my fave. It just works. Living in the Lakes, it's seen biblical amounts of mud and rain, but it just keeps going. When (and if) it dies, it'll be replaced with a v2.

 I can’t see past the Bike Yoke Revive. I’ve tried so many droppers since they first became available.
The Bike Yoke is the smoothest for longer, home serviceable and most importantly has the revive function.
I’ve had too many droppers fail or go bouncy when away on a trip - now I just get an hex key out and 10 seconds later it’s fixed. Insertion and stack isn’t everything

 "I prefer the bike yolk because I have to regularly whip out an allen key to fix it after paying nearly double if not more for it" Lol.

Get an SDG and you don't have to do jack shit.

I only serviced my two tellis posts to be nice to them after neglecting for years mostly due to the fact that it just kept working and working and working with zero issues.

Quick phone call with one of their people and had my new parts in a few days. Can't beat it.
  • 8 1
 Bike Yoke makes a great product! We're in a totally different category at $199.99 AND with a lifetime warranty, so we're nearly 50% more affordable than the Revive and with a longer warranty. The Wintek cartridge that we use in the Tellis V2 is the same as the V1 and it has less than a 0.1% failure rate on it in the 6 years we've been using it. That's astonishingly low if you compare it to others. Plus if you ever need to service the Tellis, you can strip it down and reassemble it in under 10 minutes using basic tools. There's a lot of great options out there for droppers, so that's why we focus on making a post that simply works, doesn't break the bank and covers you for the lifetime of the product.

 I have absolutely zero clue how there is so many people in here singing the praises of the Tellis post. After working in a Santa Cruz dealership and wrenching at NICA races, I can firmly say that these are one of the most unreliable, cheaply made and inconsistent dropper posts out there… only slightly behind KS in terms of issues. How anyone considers the Tellis post an “upgrade” is mind boggling to me.
  • 2 1
 Sorry to hear you had issues. What issues exactly did you have? We have less than a 0.1% failure rate on the cartridge which is astonishingly low for the category. Generally we only hear feedback about just how issue free the post is so I'd love your feedback here.
  • 3 1
 This has been the experience of several people I’ve talked to who turn wrenches, myself included.

SDG will reply that their warranty rate is almost impossibly low, but I don’t know any shop that doesn’t just bin the posts and sell a replacement from a different brand - so, it would make sense that the reported numbers are very small?

It’s nice they have so many fans - who are clearly not employees, friends, and supported riders or I’m certain they’d disclose as much - who’ve had much better experiences as they do come stock on a lot of bikes up to some very high price points.
  • 5 1
 @andrewmajor: The keyways on the V1 were a selling point (since polycarbonate can have way tighter tolerances than copper out of the box and do not develop play) and a drawback (as they take less force to sheer than copper does). That's why the V2 keeps the benefits of polycarbonate (with an improved I-Beam shape) and adds an additional copper keyway to increase the overall sheer force.

I really value dealer and consumer feedback, so I am able to talk face to face to at least 200 shops a year. I have never heard of a shop say they bin our posts when they come OEM (including the sop you were wrenching at when I visited last year) so if that's actually the case it's unfortune that this isn't disclosed with me when I spend the time to visit shops as there's absolutely no reason a shop should take more money from a consumer to "upgrade" a quality post spec'd OEM.

We're a super small (6 employees) brand and are able to take OEM, athlete, dealer and consumer feedback back and use it to directly improve the product offering.

I personally have seen 4 cartridge failures, one just this past weekend where the actual actuator piece that sticks out of the bottom of the cartridge would not fully return causing the post drop when seated. 3 with badly worn upper tubes that were caused from all the slop the plastic key ways developed after normal use, and one where the saddle clamp head came unbonded and spun in the upper tube. I agree with the comment down below, if your posted failure rate is true, which I HIGHLY doubt it is, it is mainly because you’re not actually receiving posts back in for warranty. They are all going straight into the garbage and getting replaced, which I can confirm happened in all said scenarios stated above.
  • 5 3
 @Tayrob: Thanks for the feedback. First, the upper tube is a 1 piece 3D forged piece so there's no way it can "unbond". Perhaps you meant that they keyways sheered? That would cause the post to freely spin and it's a designed flaw as we want the keyways to fail first (since they retail at $5.49 and take 5 min to replace). On the V2 this keyway is similar, but improved to include a copper keyway below the main polycarbonate one.

Our failure rate on the cartridge is indeed less than 0.1% which based on above would make sense since none of the cases you indicated above were cartridge failures and were all upper easy wear and tear fixes. The cartridge itself is made, tested and then sits for 30 days in the factory before being tested again to ensure there are no leaks. This is paired with our Trelleborg seal, IGUS bushing and industry leading quad seal design to keep all contaminants out.

If you're throwing out a post that is easily serviceable and has small parts readily available either direct from SDG or distributors and charging money for a new post to a customer that's your choice. We're not going to clog up our exciting product launch by going through addressing the issues you had as this is not the place. Hopefully you'll be at Sea Otter next week and can pop by our booth (B1) and talk to me (Devyn) and we can talk more about these issues and how they're all easily avoidable or fixable.
  • 4 1
 @SDG-COMPONENTS: I suppose there’s two ways you, or anyone reading this interaction, can look at it.

Either @Tayrob and myself, and anyone else wrenching whose had the same experience, are full of it and sharing these experiences for insert nefarious motivation>> OR, potentially, it’s worth considering that sales people traveling around visiting shops with sales people to talk to other sales people isn’t the best feedback loop.

I mean, I’ve worked at multiple shops that sell SRAM SX equipped bikes too, doesn’t change my first hand experience as someone who’s ridden and wrenched in them.

Anyway, I own my truth - I’ve certainly paid enough for it - and folks, including you, can take what you want from it. I wouldn’t normally have commented at all but I saw your standard warranty-rate reply to Tayrob and wanted to them to know they’re not alone in their experience.

Congrats on all the new OE spec.

 I got a chance to try out the V2 last fall and it has been on my bike ever since. You may only install your seat on it a handful of times but the new head design makes this dead simple - no more faffing around with bolts and nuts under the seat wishing you had the hand size of a former US president. I feel like at the end of the day you don't want to have to think about your dropper at all and just need it to go up and down smoothly and consistently - the V2 is definitely that.

 Glad we could set you up with a test model so early and you're loving the new head design so much!

 Thanks for comparing to the One-up, saves a lot of time. Unfortunately getting the maximum drop with available insertion is still the top priority with a lot of frame designs.
How does this seat clamp work? It looks like it just clamps everything in place, which would mean that adjusting is a case of loosening bolts, tapping up or down and then re-tightening? The problem with this method is that if you want to drop the nose a tiny bit but then knock it fully out of position you can't easily get back to where you started.
Being able to loosen the rear bolt and tighten the front to drop the nose seems much more controllable.
  • 3 2
 OneUp definitely reigns supreme in this category and we have a lot of respect for them with all the work they put into trimming as much height off as possible.

While we did trim substantial height from the head and actuator (as well as another 10mm off of the 200mm), we kept the same Wintek cartridge that we use on the Tellis V1, which has less than a 0.1% failure rate in 6 years of production, so we were limited in how much we could shrink the overall post. Each brand has a different primary focus and our primary focus on this post is durability, so we simply couldn't risk losing by modifying the cartridge.

 We have Tellises (Tellisi?) on three bikes at our house, and all of them just do their thing with no problems. I don't love the lever feel, but they never have a problem that would make me actually replace them with something else.

 Great to hear there's a troupe of Tellis at your house!

What about the lever feel don't you like? Typically the super soft lever actuation is one of the features people love, so I'm interested to hear what you don't like about it.

 @SDG-COMPONENTS: I think I just like some more firmness and feedback. I really enjoyed OneUp's older stubby little lever (V2 maybe). I even had that lever and your post on my previous bike.

 @Genewich: that makes sense! Our actuation is definitely soft which we find is a selling feature, but it's certainly not for everyone!
  • 1 0
 @SDG-COMPONENTS: I'm gonna pop in here because as great as the Tellis is, the lever just doesn't work for me either. I was actually happy to see you don't include it with the V2. For me, I think it's a mix of the ergonomics or like physical design and the action or "throw" which I feel like negates the ease of actuation. Pretty sure it actuates well before you reach the end but my brain wants to push all the way which kinda strains my hand. Less of an on off feel. And yeah getting it to a spot where I don't feel like I'm trying to twist my wrist around my bars is tough. Hope that makes sense. If not, A/B yours with WolfTooth lever. The WT feels tighter, has less "throw", idk if im using that word right, and therefore is easier to position. I like a little bit of resistance too, tellis lever seems sleepy. Works perfect but no match for the WT IMO.

 @MidwestMountains: different lever strokes for different folks! Your feedback is noted and appreciated. We've actually since added a hard stop to the lever throw on the latest revision of levers so levers that come OEM and future aftermarket levers will all have this update.

 ATTENTION SDG: My YT Izzo came with the V1 and it has been flawless other than having quite a bit of wobble. My new gen YT Jeffsy came with the V2 and it has much less wobble. However, while I like the side bolt clamp design, the saddle tilts back on every ride no matter what the bolt torque is set at. How can i prevent this slippage?

 Please send an email to or shoot us a PM here and we can sort you out. There was a running change from M6 to M7 clamp hardware for OEM posts that shipped prior to the launch. While the M6 hardware passed 2x ISO standards, we increased the hardware size so you could go up to 17nM of torque.

 Got my 1st Tellis in 2019 on a YT Capra - the thing is solid, still has the original cartridge after nearly 10,000 miles - still running strong. The only other dropper I can compare with is a OneUp w/ longer travel but having to take off the seat to inflate the airchamber is a mega-dirge. Not the biggest deal, but even getting up to 300psi on any hand pump - ya lose 50-75 lbs of air unscrewing the pump. Meanwhile, the Tellis just chugs along w/o routine maint. DEF'LY gonna buy another Tellis next... now if they just make a cable-free / electronic version, I'd buy that. Can't stand charging stuff, but fighting dropper cable housing inserts is not amazing.

 Right on! Stoked you had such a positive experience on the V1 and for putting it through one hell of a test. Hope to have you on a Tellis V2 whenever you're ready for an upgrade. It'll take all the best aspects of the V1 (it just works), but so many tech features have been added to elevate the offering (while bringing the price down at the same time and adding a lifetime warranty).

 @SDG-COMPONENTS: I'm suprised to read some of the crap comments here but - its all perspective. I'm sure some mechanics are seeing far more droppers than I am but w/ 10K miles (and original air cartidge) and only 4-6 months maintenance intevals - and I might add, near immediate personal service when I've emailed - I'm impressed. A mechanic has never once seen my SDG because its been flawless (and I maintain it). Overall I'd say that people who have to have a mechanic service their droppers don't really know bikes anyway - most are easily serviced even by morons.

I like my OneUp dropper too but it has more side-to-side play new than my (older) 5-yr SDG. Otherwise in terms of sound, smoothness - they are both about the same. The downer w/ the OneUp is having to take a seat off to add air to a post on unpredicatable intervals - I'll go SDG for never having to do that because of the sealed airshaft.

One last point: the SDG uses the natural cable end to snug into the actuator. The OneUp uses an additional barrel (no clue what these things are called) that the cable-end snugs into THEN that goes into the actuator - so if you drop or lose that extra piece, you are screwed on your post until you wait two weeks for OneUp to mail you one for $15, shipped (which I did). The SDG design of the cable fitting directly into the actuator with no additional hardware is a better idea so I'll take the "massive" 0.4 inch less travel on the SDG and sure... that has ruined my riding ever since, but its all tradeoffs Wink

 @Mtn-Goat-13: Everyone is going to have a different experience, so we're stoked you're one of the many that has trusted us and had the exact experience we designed the post to have. There's a reason why so many premium OEM's trust us (Santa Cruz, every single YT, Pivot, Norco, Devinci, etc.) with their spec and more so have increased their spec year after year.

We'll keep focusing on making a post for your everyday rider. Every single feature that you find on the Tellis V2 has been designed by focusing on simplicity and durability that the rider who just wants their product to work can appreciate.

 Real question about droppers in general. Pinkbike praised the hardware design on the Tellis, but you still have to remove the seat to fill it with air. The only dropped I've come across that solves this issue is the Specialized CommandPost that will knock the wind out of your sails if you're not careful. I cannot stand the action of the post itself. but I love that it has an external air port under the saddle.

Is there a legitimate reason this design hasn't caught on?
  • 3 1
 Our posts use a sealed Wintek cartridge which doesn't have adjustable pressure. We find that cartridges that have adjustable pressure are commonly more prone to fail as air can seep out of the valve and grit can work it's way in there. For us, we like having a post that is set from the factory (our vendor leaves the cartridges for 30 fays after production and then tests to ensure no leaks) plus our premium sealing design help us to have an astonishingly low failure rate of under 0.1%. More brands seem to be moving to this design as well as OneUp's V3 dropper moved away from adjustable pressure to a sealed cartridge similar (but not the same) to ours.

 @SDG-COMPONENTS: Love to hear that you're addressing this problem! Nothing worse than starting a ride only to realize your dropper needs air!

 Do you still need to be a 200lb rider to get the seat down easily? I liked my Tellis, but as a very light rider, I found it was a pain to get the seat down with my weight. Almost like there's just too much air in the thing. This is why I switched to a PNW post as I could add the amount of air I wanted to make it require less force to get down. I do still use my Tellis lever tho cuz for some reason I find it better than the other options everyone else seems to like.
  • 1 1
 Our compression force actually tends to be one of the lightest out there (we've tested this with a force gauge), however tons of variables (such as seat tube angle, saddle position, bushing orientation, etc.) come into play that'll affect how easy it is to compress. With that being said the V2 has a larger diameter stanchion (26mm V2 vs 25mm on V1) which decreases stanchion deflection on slacker seat tube angles or saddles being run far back on the rails.

Personally, I'm 215lbs geared up and run a 230mm Tellis V2 and I found the V2 to be noticeable easier to compress compared the the V1 simply due to the decrease in deflection.

 I wonder how the angled clamp bolts will hold up over time, and if the standard fore & aft configurations actually prevent loosening and better resistance to impacts to nose and back of the saddle.

 This post came on a bike I bought this year, I sold it off because I wanted more drop. But I absolutely love the clamp system, easily best I’ve used in recent memory. I don’t understand how OneUp, PNW etc can get it so wrong.
  • 2 1
 I have used this post for about 6 months now and am super stoked on the overall feel the post! It has a very smooth feel up and down and is always ready to be in the right spot when I need it! Super stoked on the seat clamp style as well! Overall super rad post
  • 2 1
 I've had the opportunity to ride the V2 for a few months now and I am loving it. Swapping saddles and making adjustments with the improved saddle clamp is so easy! The bolts on the side mean I can loosen and tighten the bolts with a Y-wrench with plenty of room to spare. Getting proper torque is important for the clamp bolts, but once it's set up, my saddles haven't budged at all despite some awkward hits on the trail. The rest of the post's setup is very simple and straightforward including the travel adjustments. I have the 230mm travel on my Ripmo (L) and ended up needing to shim it down to 220mm. A couple of minutes was all it took without even removing the post from the bike. The shorter stack height from the clamp and the shorter actuator of the V2 allow the post to just barely fit at the 220mm travel setting with the post slammed in the frame for my saddle height. It ends up bending the housing a bit to exit the frame near the BB but it doesn't impact the functionality of the post or bind the cable. If I wanted the housing to be a little cleaner, I could shim the post to 210mm and just not have the post as slammed in the frame. I love having that amount of travel though! The post is super smooth and has zero side-to-side play after months of use. The Tellis V1 is known for having a stellar reputation for durability and reliability. I expect to have many seasons on this post without issue, and to me, that's worth the slightly longer stack height and length over other posts as the author mentions.

 Yeah. If it hasn't got I-beam, I'm going to buy something else.

Still can't understand @SDG-COMPONENTS 's logic behind trying to be competitive in a established market when you basically have a monopoly already in a standard that is superior and established on the market. Imagine SRAM not making any UDH-derailleurs.

 @mattbeer But is it still a slow action like the old Tellis? In this respect the Oneup have typically been much better.

 What more out of a dropper post do you want Pinkbike?
If anyone was to complain about something on their bike, it's my wife. Thus, after listening to complaints about her post, I finally put an SDG V1 on her bike. Zero complaints and zero noise on her post now.
I had a SDG Version one on a Kona HeiHei XC. After 3700km on it I had zero issues, I never even unscrewed the collar to clean it lol. It just worked perfectly. Only thing I regret after selling that bike was not taking the Tellis post off of it. Now my 2023 Spur has a OneUp dropper that's insanely finicky and usually doesn't pop up all the way.
Can't wait to put a V2 tellis on now and garbage can my OneUp.

 Have you tried backing off the seat clamp torque a bit? I had that problem with a OneUp 150mm v2 and loosening the steat clamp a bit resolved the extension issue.

 The Tellis V1 I've had since 2018 and on 5 different bikes and hasn't skipped a beat. One full service in that time and the occasional clean and grease under the collar and its smooth as day one. Stoked to try out the new V2!

 TLDR: Tellis released a fairly good dropper post at a decent price, but it's not as great as the OneUp V3 for just 50 bucks more.
  • 2 2
 OneUp's primary goal with the V3 was short overall height and weight. They make a great product and we have a ton of respect for what they do. Our primary goal was durability (to improve on our already astonishingly low sub 0.1% cartridge failure rate), simplicity and competitive pricing. If your primary goal is to have the most reliable post, with a life time warranty, that's more than 25% more affordable than OneUp and offers global domestic support (our German distributor, Cosmic Sports, carries all small parts in Furth) then we hope you give the Tellis a shot.

 To your point. there are not many ways to save 229 grams for $55 on a mountain bike.
  • 3 3
 @ReformedRoadie: claimed OneUp weight in the review is off as it should be 129g lighter, not 229g. Still a very solid chunk of weight to shave off for $70 ($199.99 vs $269.99 starting MSRP's) so hats off to OneUp for the work here. We're more of the view that durability is paramount to anything else, but as a reformed roadie, I guess it's hard to get away from gram counting! Wink

 @hardtailpunter: I haven't tried the Tellis or the OneUp v3, but I have multiple OneUp v2 posts because I wanted the extra drop afforded by the low stack (~210mm drop vs. ~190mm from competitors). The only problem is the OneUp makes compromises in quality/durability to get that extra drop, so even though I could hypothetically get the full 210mm, the post doesn't function properly when it's slammed to the collar. If you do the seat clamp up tight enough so it doesn't slip, the post binds. If it's loose enough not to bind, then the saddle spins all the time. So I had to shim the post down to 190mm anyway and clamp it 20mm below the collar to get it to function properly. Now I'm just left with a cheap post giving the same amount of drop as competitors, but the sealing is shit so it needs new grease every couple weeks and frequent air top-ups too.

TL;DR is in future I will avoid OneUp posts for something more reliable with a bit less drop.

 @scotteh: Yea, I'm not so high on the OneUp dropper hype train either. I've owned 2 v1 and 1 v2 and they're good not great, well enough to keep using what I've got. It was the ease of purchase from their site and their customer support when I've had issues with them that makes them a great company, but I'd prefer to not need great support in the first place. Future posts will be something damn good.

 @scotteh: I'm not saying you should have to do this to a finished product, but since you already have the posts: some people have luck sanding down the bushing
  • 1 0
 @DizzyNinja: totally agree. The OneUp works reasonably well if it has fresh grease, max PSI, and is clamped more than 10mm below the collar, but the performance degrades so quickly and it's annoying constantly servicing it. I've just rebuilt it with the new v2.1 midcap assembly, hopefully that helps keep the grease inside a bit longer...

@jdejace: interesting, thanks man! it's crazy how hyped those posts are considering even with fresh grease, maximum PSI, and carbon paste that they bind with ~3nm clamping force when slammed to the collar. Basically a defective product.

 Can you upgrade an older Tellis V1 with the new V2 keys and bushings?
  • 1 0
 Unfortunately not as the new keyway requires a new upper and lower tube to fit it. The new actuator is retrofittable to the V1 post so you can use that to trim a bit of height off of your V1.
