Review: Logos Eudae 29 HD Carbon Wheels
There are many wheel brands out there - it's one of the areas of the industry that has seen the largest number of new players in recent years. While it wouldn't be fair to say that these brands aren't creating unique and individual parts, I think it would also be fair to say that some of them have ridden the wave of what other older brands have done in the past and learned from their wins and losses. Logos Wheels could be said to be one such brand. Launched as the wheel-wing of Thesis, which makes semi-customised gravel bikes, the brand really got into full swing when DT Swiss's dual ratchet patent expired.

DT Swiss has since moved on to a single ratchet and fixed piece. While this could be said to be lighter, the two ratchet systems have the benefit of allowing both pieces to float and align with one another. While Logos didn't say, it looked like many of the DT Swiss spares would be interchangeable.
I like the simple and clean branding.
Design & Specs
The rims use a 31 inner width and share the same rim profile as the Eudae trail wheels. However, the HD versions feature a heavier-duty carbon layup and heavier gauge spokes. The rims aren't front-rear specific and feature 3.5mm of asymmetry. When building an asymmetric rim, the reduction in dish required means that the spokes can be of more even tension, which should make for a stronger wheel.
Straight pull and centerlock... the comment section will be good at least.
When building carbon wheels, sometimes the manufacturer will reinforce around the whole nipple seat for greater strength and to stop you from ripping the spoke out of the rim. While this is effective, it also affects both compliance and weight. Instead, Logos chooses to reinforce around each spoke hole individually. The rims also feature a mixed modulus layup, with T700 carbon in impact zones in places that will see impacts (the side and lip of the rim) and T800 in areas that will require more of a focus on stiffness. The rims have their holes drilled on an angle to ensure an exactly straight path from the rim to the hub flange for the spoke. This alignment should not only reduce spoke fatigue but also help create a wheel that's easier to true to finer tolerances. Speaking of which, the rim is made to 0.3 mm lateral and vertical tolerances.
The hubs are straight pull, but before you head to the comment section, this is actually done for good reason, and a reason that all riders will benefit from - this wheelset only uses one spoke length front and back, left and right. Using a straight pull hub enables this, and I think it's worth it. However, the centerlock rotor mounts are harder to justify.
The wheels have a max rider weight of 130 kg (287 lb) and are also available with upgraded Enduro XD15 ceramic-hybrid bearings. These will cost an additional $551 over the decent-quality and very adequate sealed Enduro bearings that come as standard.
Look familiar?
The bike they found themselves on... hubba hubba.
Test Setup
I've spent the better part of a year riding these wheels on my enduro bike. They've seen a lot of miles around Squamish and many bike park runs over the summer. I've had a few different sets of tires on them, including my favoured Assegai and DH2 tires in a variety of casings. I typically run reasonably high pressures but experimented at times with lower ones, if only to see how the rims handled impacts and whether lower pressures would induce burping.
These wheels share the same hub as the non-HD version but have a different, tougher rim.
On the Trail
Carbon wheels have come a long way, and the Eudae wheels are right on trend with what you'd expect from a high-end carbon wheel. Comfortable, yet still light yet reliable. It really feels carbon wheels are more often good than they are bad now, which is great for the consumer but sadly bad for the reviewer when it comes to trying to say something unique or different.
These wheels are a good mix of compliance and stiffness. On fast, choppy trails, they offer good tracking and take the sting out of features. That said, they're obviously not as compliant as something like the Berd Hawk30 wheels I also tested last summer, but for something a bit more conventional, they're very good.
Comfort is always a balance, and these wheels also offer the sweet spot of priorities. They're stiff enough through turns, and the wide rim offers a good level of stability for the tire. The bead interface works well, and I have never suffered from burping of any kind.
I like brands that print the ERD on the rim. Seems like an easy win to me.
Durability
These wheels have seen lots of hot and fast bike park laps, been hit off every root in Creekside, and seen more than their fair share of wet weather riding and washing in Squamish, but they still spin very well. They never required a retention and have been incredibly reliable. Apart from changing tires, I haven't touched them since first putting them on the bike, and really, isn't that what we all want? I often wonder whether straight-pull spokes help with this as a spoke and nipple that could twist without unthreading would mate nicely with a carbon rim.
Pros
+ Reliable and hassle free
+ A great blend of stiffness and comfort
+ No-fuss internals
Cons
- Centerlock only hubs
Pinkbike's Take
 | The Logos Eudae HD are the real deal, offering reliability, a good ride quality, and a reasonable price for carbon wheels. The rim has some great features and has withstood plenty of knocks over the test period. |

Centerlock is the epitome of a "solution" no one asked for and is objectively worse.
I've seen maybe two stripped 6 bolt bolts in my day... and they were able to be eventually removed and the threads re-tapped.
I've seen dozens of stripped centerlock treads that toasted the hub.
But the fact of the matter is, a review of a $1300 wheelset has become entirely distracted by the centerlock issue. Which for any manufacturer should be reason enough to not use centerlock on their wheels.
Each system has it's own merits, and disadvantages. I prefer one system over another simply because it utilises the same tool I can use across 90% of the rest of the bike.
None of us are removing rotors often enough that it's worth arguing about, and if anything is actually coming loose on your bike during a ride, you've not done it up properly to begin with.
I was just saying that *in theory*, you could loosen a CL lockring if the conditions were right.
centrelock sucks...
Fella above claims it's happened more than once, I've never seen/heard of it happening when proper torque is applied. Sounds like user error.
Think the one-up tool has a centre lock / cassette lock ring tool on it
More/cheaper rotor choice in 6. Multiple redundancy (XC racers run 3 bolts!). More freedom to shim when mixing new/old/cross-brand.
Side note: I once lost 3 of 4 chain ring bolts on a ride too and was just told that I need to replace my crankset due to damaging the spindle from a loose crank arm. I think I need to do a bolt check more often.
I've not had a cassette come loose, but I know plenty of others who have, so CL could too. CL hubs and rotors are necessarily more complex to make, so will be more expensive. Chances are if you bend a 6 bolt disc, a reasonable bike shop will sort you out a replacement from stock. Not so sure on CL...
The fewer specialized tools needed to work on the bike, the better.
But least your rotors will be straight when you get to piece your bag of dented aluminium/carbon dust back together.

One of the things I would care about most (in addition to durability and price) in a wheel is how light the rim is, since this is the primary rotational mass. Everything else being equal, a lighter rim is going to be more impactful to the agility and efficiency of the wheel.
I dunno why caring about rotational mass is seen as nerdy. Have you ever felt the difference between, for example, running cushcore and not? Adding even 50-100 grams to the highest leverage point of the wheel is very noticeable.
Anyways these wheels are about 300g overweight for the price
Oh Henry, you give us way too much credit.
Why buy rebadged Chinese stuff with a heavy markup?
I had a set of SRAM Roam 60 rims with straight pull bladed spokes and I kinda wished they were just J-bend.
Those rims needed a lot of truing, and I didn’t really enjoy holding the spoke with one tool while truing with another.
They were kinda fragile, and eventually failed anyway
Guess that goes for either spoke.
I gave up on truing those rims because of “stiff nipples”. Watching those blades twist and waiting for the nipple to “turn” was painful. And the nipples were aluminum, sometimes crack while truing!
Those rims are gone. I never see them anywhere.
I’m actually surprised to see a new product with centerlock. Guess the war never really ended..
What you get with that is the most durable bearings available, which come with a lifetime warranty, and believe it or not, actually get faster as they wear in.
Enduro uses a proprietary steel alloy for the bearing races that is hard enough to stand up to ceramic balls, but unlike the chromium steel races used in other ceramic bearings, is stainless. This allows them to be effectively maintenance free.
Omg, it's so joyous!
no.
