Atherton Bikes have launched what they call "a hard-hitting big mountain enduro bike". The AM.170 has 170 mm of travel at the rear, with a choice of 170 or 180 mm forks and coil or air shocks. It runs mixed (mullet) wheels.
Atherton say it incorporates learnings from their World Cup-proven mixed-wheel downhill bike, the AM.200, and was designed with Dan Atherton. While it's designed to excel in bike park terrain, the company describe it as an "all-rounder" and emphasise its versatility.
"The AM.170 is equally happy doing all day big mountain days as it is taking on the Oakley line", says Dan Atherton. "If I had to choose just one bike from our range to ride every weekend, this would be the one!”

• www.athertonbikes.com We've known a longer-travel enduro bike was coming from Atherton for some time, but I expected it to be more of a dedicated park bike. It's pretty interesting to hear Dan Atherton describe it as the bike you should have if you can only have one bike. Sure, he's probably biased (although Atherton do offer two shorter-travel bikes) but at least somebody agrees with me that
a long-travel enduro bike is the only bike you need.
The AM.170 joins the AM.130 trail bike, the
AM.150 trail/enduro bike, and the AM.200 downhill bike (AM stands for additive manufacturing, not all-mountain). It shares much of the same features which make Atherton's bikes stand out from the crowd. The frame is constructed from custom carbon tubes and 3D-printed Titanium lugs; an adaptable approach which allows Atherton to create 22 different sizes. Reach numbers go from 410-530 mm in 10 mm increments, with options for seat tube and head tube length too. But don't worry if that sounds too hard to choose, Atherton's website recommends a size based on your height, arm span and inside leg measurement, or you can just give them a call.
It uses Dave Weagle's 6-bar DW6 suspension layout, which offers good pedalling support and plays nicely with the 3D-printed construction and custom-sizing. Atherton are tight-lipped about the precise kinematics, but based on Atherton's other models it's safe to assume there's a generous amount of anti-squat and leverage progression.
One thing that sets the AM.170 apart from its stablemates (aside from the travel) is the straight seat tube, which allows for very long dropper posts. The actual tube profiles in the front triangle are common to all Atherton bikes (although they are cut to custom lengths depending on the model and size), as are the hardware and most of the bearings. The rear-end tubes are the same as the AM.150, but the lugs are specific to the model (and frame size).
GeometryThe 64-degree head angle isn't quite as slack as you might expect given some enduro bikes are going below 63-degrees these days. The seat tube angle steepens for larger frame sizes, starting at 77 degrees and going to 78.5 degrees. The chainstay length changes slightly too, from 430 mm to 440 mm. This should help taller riders to feel less "off the back" on the steepest climbs.
Models & pricingIt's available as a frame, with a choice of Fox DHX2 coil or Float X2 air shock, for £4,500. There are also three full builds, all of which use Stans Wheels, Continental Kryptotal DH tyres, FSA bar and stem and Hayes Dominion brakes. The shock (air or coil) and fork (170 or 180 mm) can be customised to order, and Atherton can accommodate other upgrades or swaps, bolstering the personalisation offered by their sizing strategy.
The starting price for a full bike is £6950 for the Build 3. With a choice of Rockshox Super Deluxe Ultimate Coil or Air sock, and Zeb Ultimate fork with either 170mm or 180mm up front. The drivetrain is SRAM GX Eagle.
For £ 7900, Build 2 comes with a choice of Ohlins TTX22.M2 Coil or Air shock and Ohlins RXF38 fork, with either 170mm or 180mm.
Finally, the £8,200 Build 1 gets a Fox Float X2 or DHX22 shock with either a 170mm or 180mm Fox 38 fork.
All builds are compatible with SRAM’s new direct-mount drivetrains, which are available as an upgrade.
This is a stupid argument. the text reads, "If I was only allowed to choose one bike, this would be the one". It is also a promotional story about the specific bike, so it would be ridiculous if he said "Our other bikes are better than this, but its still cool". He's trying to drive sales towards the bike, which is why he said it. His option is useless, because he's trying to promote this bike. I don't blame him, because he's just trying to do his job and make money to feed his kids, not write an honest review.
Also, the reason we need warnings of coffee is because of the one person who got third degree burns from a Mcdonalds coffee that was spilled on her.
Because shockingly this frame with 22 sizes, is $600 cheaper than the SB160 frame only.

(F orange tho they fugly)
The bike market is on a cliff and it is my humble opinion that there will be very few buyers of high end bikes by the end of this year, as the CMBS default rate starts to really hit the banks globally.
Canadians can just get a We Are One Arrival 170 with GX AXS for just over $10k out the door and save $5k... or ya, buy three Chainsaws.
Cool tech and the customization is awesome though
Weagle is behind a lot of different layouts (DELTA, DW-Link, Orion, Split Pivot, DW6 off the top of my head) and they all ride the way the brand determines when working with him on its implementation. At the end of the day it's the shape of the curves that matter, not the linkage layout.
They haven’t ridden this bike yet, but PB still included “firm pedaling support” under pros, which you can do without pictures, because generally a bike company working off the same platform (DW6) and tuning for the same kinematic feel across their bikes tries to deliver a similar experience across the line, and this thing is a little over an inch away from the heavily reviewed AM150… which has a well known great pedaling platform.
I did not claim certainty, and it could be that the chainsaw out of the box is more efficient uphill than the AM170. But it’s reasonable to believe this is not the case, based on a lot more than “pictures”, which by the way is enough to power the famous and highly useful linkage design blog.
oh my goodness, what if we all put this energy into trail work instead. I’m still too injured to ride but surgeon says I can dig again in a few months and I can’t wait.
I'm just holding out for Dave Weagles new upcoming 8 bar system.

Dan Atherton asked us for an all-rounder, that would be both a big hitter in the bike park and also a beast out on the trails. To give this balance between agility and composure, and after extensive testing, we landed on a mullet.
Why not offer both? In order to best optimise the bike (for example the kinematics, stiffness characteristics and packaging) we do not offer a system that allows the wheel size or geometry to be altered. If we were to offer a full 29” option, we would look at a full redesign, from the kinematic to the packaging and potentially the frame architecture.
I’m sure it goes without saying that we strongly believe you will not be disappointed in the bike’s performance. We will look to include a selection of AM.170s in our demo fleet in the near future, so why not come and try one to see what you think? If you’d like any more information on the AM.170, don’t hesitate to get in touch.

A 75.5 'actual' seat angle with a 440 chainstay is outstanding work by the frame designers - and a super rare combination of numbers that I really like!
So many brands cop out and use lazy designs, wasting space in the linkage and ending up having to run slack 'actual' seat angle numbers to accommodate shorter chainstay (or they do the opposite and run a steep actual seat angle and try then and market a 450+ chainstay as a performance gain, when it's just a design they're forced into because of their poor linkage planning....
You're absolutely right - it is all too easy to massage your geo numbers into something that makes your life as a designer easier.
Cheers, Rob (AB Design Team)
It nailed the reach though.
Our fit calculator prioritises choosing a size which has the shortest ST length that still allows the user the longest dropper post length. This is so that you can lower the seat post as much as possible to get it of the way for big bike park days. if you would prefer to minimise the exposed seat-post then you can go for the longer seat tube option.
Hope that helps!

But I love the number of sizing and fit options, they have definitely took advantage of the technology they have. This premium bike is actually worth the price. Good job.
If I could I would, but a bit too expensive for me.
Its a bit of a myth that carbon can't be repaired effectively. Plus, because our tubes have simple geometry and a defined layup schedule they are particularly well suited to repair in this way. You can achieve the original strength post repair.
Cheers, Rob (AB Design Team)
I'm glad they adjusted the length based on the size (435mm to 440mm), I think they could have used more steps in the adjustments, with (for my preferences), 450mm on the larger sizes.
They used to offer custom geo for another fee, but apparently people got "too" custom with it, and it was too much overhead, so now I think the "custom long chainstays" are off the table for now.
Hoping more start soon
Is there a reason for that @Athertonbikesteam ?
I noticed the race team is on dominions now too
Is the air sock so I can blame the conditions and not my skills and new bike for not dropping into the Hardline course?
Jokes aside, I think it looks great. I would consider one of these...
I nearly bought an 130, until I realised I couldn’t get the dropper I’m used to in the seat tube.
The starting design brief for this bike was "a bike that Dan can ride all day in Dyfi Bike Park and then be able to ride the enduro loop (full of rocks, roots, stumps etc) and not feel compromised on either!" He made sure he got this!
Best thing is to try one out for yourself and come and do a demo! Cheers.

but since he‘s a factory rider that doesn‘t count
The aesthetic is definitely a "marmite" factor - it isn't for everyone, but that's something we are happy to live with!
Our frame design is driven from a very simple design philosophy - honest engineering: using the right material, right process and right form in the right place. And the engineering reality is that complex form metal high specific strength lugs, bonded to simple form high specific stiffness tubes is an incredibly efficient way to make a structural triangle.
The engineering makes the decisions for us! Cheers.
Your bikes look killer. Any option for a demo ride in the USA?
The 2nd context is down to pricing and 'finance'... i can get something like a Session/Gambler on 0% finance from Blazing Bikes... but sadly Atherton can't match that that the moment... which REALLY would swing one of their bikes for me.
I absolutely love to support the small guys, especially with their history and love the looks/ethos... but it's got to make sense in all contexts.
Atherton: Yes
Also, who's breaking their cranks? Genuinely curious to know. Do you have any links?
