Review: Crankbrothers Synthesis E11 Carbon Wheels

Jul 24, 2019
by Daniel Sapp  

Crankbrothers took a different route with their Synthesis carbon wheels by creating front- and rear-specific rims. There's a stiffer rim in the back to better handle bigger hits, while the front rim is supposed to be more compliant in order to provide extra traction and comfort.

The Synthesis wheel system comes in three different configurations - one for XC, one for all-mountain and enduro riding, and one for DH. We've had the middle sibling, the Synthesis E on test for a number of months now to see how they fare in varied riding conditions and to see if they actually do offer a benefit over a traditional wheelset.

There are also multiple hub choices. Our test wheels were laced up with Project 321 hubs, and
Synthesis E11 Wheels
• Intended use: Enduro/All-Mountain
• Carbon rim, front and rear-specific "tunes"
• 27.5" or 29" options
• Project 321 hubs, 2.5-degrees quiet engagement
• Designed to fail in a propagation mode
• Lifetime warranty on rims
• 1,825g (29" wheelset)
• $2,399 USD
• $699 USD (rim only)
the wheels are also offered with Industry Nine's 690-point-engagement Hydra System hubs. Synthesis wheels come with a lifetime warranty, which covers rims that break during normal riding conditions. In other words, leaving them behind your car and backing over them doesn't count.

Synthesis isn't the first to offer front- and rear-wheel-specific rims, but they have taken the concept to the next level.


The Synthesis carbon wheels are designed to work as a system and are the creation of Jason Schiers and Mello Bouwmeester. Both of these guys have quite the background in the bike industry, which we went a little more in-depth on with our "First Look" of the Synthesis wheels last year.

The concept of the wheels is that with more compliance the front wheel can more easily find its way, and then with more stiffness in the back wheel the bike will track well. This is similar to how most riders run a little less pressure in their front tire than the rear. If the front wheel is too stiff, it won't flex and hold the trail. Rather, it will skip around and ride poorly. Conversely, the rear wheel has to be stiff to manage larger hits and power through impacts with more force.

Crankbrothers' Synthesis rims use massively thicker walls in high-impact areas. The front rim (left) is wider and designed to be more compliant than the heavier-constructed rear-specific rim.Crankbrothers photo

After a lot of prototypes and back-to-back testing of wheels, the team settled on what they felt was the ideal combination of the two: a more compliant front and stiffer rear wheel. The front wheel has a reduced spoke count, lighter gauge spokes, and lower spoke tension. The rim itself is slightly lighter and is slightly wider than the rear. This is to pair with running a slightly wider tire up front and allow the tire to have a rounder profile.

The rear wheel's higher spoke count, higher spoke tension, and narrower rim stiffens things up and sharpens up the tire's profile for cornering. The rim flanges are made thicker to handle higher impacts. Crankbrothers claim that this combination of rim design and wheel build creates a more durable yet compliant ride.
Mello wheels
Synthesis also incorporated dissimilar tire widths into their front/rear wheel equations, as most riders choose larger volume tires up front.

Safe Failure Mode

As everything can fail, Synthesis wheels are designed to fail in a manner that is controlled, rather than catastrophic. Schiers claims he has been obsessive about the way carbon fails and has worked hard to figure out how to manage catastrophic failure ever since he made the first Edge/Enve wheels years ago.

The ultra-thick carbon sections have some traits in them that can't be duplicated in traditional thin-wall tubular-section rim types. The resin system used in the carbon is a special high-impact formula and the layup schedule is tailored to disperse impacts. Some of the layups and materials are similar to those that protect F-1 drivers in race cars where safety is paramount.

The wheels are available with Project 321 (left) or Industry Nine's Hydra hubs (right).

Schiers says that if the Synthesis rims do fail it would be in a propagation type mode, with the damage spread across a wide area of the structure. Like the properties of an aluminum rim, the carbon is constructed to produce a noticeable deterioration - a heads up - that will hopefully catch the attention of its owner before further damage leads to a complete failure. Schiers believes that anyone who is developing carbon wheels has a responsibility to manage their failure modes to ensure a safe and controlled event.


I've spent many hours on the Synthesis E wheels. They've been my go-to on the Yeti SB130 I've been using as a test sled. That means I've had plenty of opportunities to compare the E 11's to the alternative carbon and aluminum hoops that I've swapped off and on more times than I care to count.

I'm happy to report that I experienced no issues. The high engagement of the hubs was great, and the wheels delivered an excellent ride quality. I wasn't easy on them either. I thunder cased multiple rocks and ignored that I was running seriously low air pressure at times, yet I never flatted nor suffered
any damage to the wheels outside of the standard rock gouges that are unavoidable in North Carolina.

different ride experience. I was getting kicked around and couldn't seem to find the sweet spot on the SB130 anymore. Eventually, I did get my groove back with the other carbon wheels and didn't give it much thought - until I swapped back to the Synthesis. The difference in ride quality was noticeable.

The difference between the ride quality of the Synthesis wheels and their high-end competitors is quite remarkable. Upon riding these wheels, it's easier than ever to comprehend that there's a lot more to a wheel than it just being stiff and strong. Compliance and ride quality directly translate to comfort and control on the bike. Just like the difference in vibration damping an aluminum handlebar has vs a well made carbon bar, it's easy to feel the difference in the ride characteristics of the Synthesis wheels.


+ Compliant and comfortable ride
+ High engagement hubs
+ Lifetime warranty

- Expensive
- Benefits could be negated if not used in the full system

Pinkbike's Take
bigquotesCrankbrothers have designed a wheelset that validates their claims - the Synthesis wheels have proven to be compliant and durable. The wheels deliver a better ride quality than many other options currently on the market, and if they fit your budget I recommend them for riders searching for durable, high-performance carbon wheelset.Daniel Sapp

 Pretty cool that they've made a carbon wheel that's almost as good as aluminium ones

 That was my exact thought as well. I get the appeal from a decreased weight standpoint, but the difference is so marginal. Especially when you have the added trade off of having a wheel that's rigid as hell.

 @skycripp: Most good aluminum wheels weigh about the same as good carbon wheels these days anyway. I don't really see the advantage of carbon wheels anymore...

 Some carbon rims are better performance wise. Especially the ones with the strip of red tape over the valve, so that everyone knows what they are and how much you paid. Genius marketing by SC. I felt noticeable benefits climbing, and I have had a few very hard rock strikes through the rear wheel without any issues. It would be interesting to test them against some of the cheap Chinese rims like Lightbicycle etc.

 @JohanG: Which brand and wheelset is that? I my recent searches, you can find some very light carbon hoops, but found the lightness usually comes from hub and spoke selection which you can copy on aluminum.

If you're on very light carbons, they're either a brand or wheels I wouldn't trust or XC variants vs something that will stand up to the abuse of AM/Enduro.

I have a set of 26 Light Bicycles on DT Swiss 240s and CXray spokes. Enduro build. Thrashed hard and still true. 1450g.

 @islandforlife: Interesting, I took at look as well. It looks like the DT Swiss XM 481 29" Rim (Alum 30mm internal width) rim is 534g/rim and is $130/rim.
The light-bicycle AM930 is 440g/rim (same internal width) and is $280/rim. So just under 200g (about 1/2 lb) difference for the wheelset if you get the same hub/spokes/nipples, etc. About a $300 cost difference between the rims for a wheelset.
Stan's flow MK3 are a similar weight at 527g/rim (slightly lighter), but the EX3s are 618g.

 @sarahlh: I know a guy who flip/flopped between a custom build here in Canada, and a cheaper light bicycle setup.

He ended up going with LB. He ordered dt240 J-bend hubs with the rims. They send him wheels with straight pull hubs, and the wheels were built so much over tension that the nipple holes were bulging and distorted.

They refused to replace the wheels, but did eventually replace the rims. He was left with hubs he didn't want, and left paying the bill to have them built here anyway!

LB service is terrible, judging by what he went though. And while they might make good rims, they build a terrible wheel!

Hi mate, I have a set on my hardtail (enduro build) and another on my DH bike (DH build, obviously). Just got back from Whistler on the DH bike actually. After 3 years, there is a very slight buckle in the back of the DH bike's wheel, which I think is due to a bent spoke.

I've had very good experience with both wheelsets. One was built by a local guy here and the other was built by LB themselves.

I wouldn't hesitate to do it again. Great wheels!

But still not a good piece of marketing, let's compare it to SC's "It took Danny 2 hours of mashing the wheel without a tire to crack the rim". CB say "we designed this product so that there is a lower chance of killing yourself when it blows up".

In any way I would hope DFMEA is something known to people who design bike wheels this expensive no matter the brand
  • 13 0
 @KondziuNS: The other point to consider is that this is a review. We're doing our best to fully explain how the wheels work and validating whether they do or don't perform as they are supposed to. These are our words, not theirs so it's irrelevant that it's not a good piece of marketing. It's a piece of information that hopefully helps someone understand how the wheels work.

 @danielsapp: Just out of curiosity, are you aware if other bike industry companies perform FMEA in a similar way to CB shown here?
  • 5 0
 @KondziuNS: Yes, some do and will say they do, others don't, and a lot more don't go into what sort of testing they do in order to protect trade secrets. It would be good to see more FMEA with high-stress components industry-wide. With certain components such as wheels, it should be required. Anything can be broken but catastrophic failures shouldn't be deemed as acceptable under remotely normal riding conditions. (Failure Mode Analysis, FMEA, is how things break - for those who don't know what that is)
  • 12 0
 @KondziuNS: all rims fail past a point. Santa Cruz included. The Danny Mac video is marketing, just like anything else - like you say. And this is just one aspect of these rims, that they aren't making a 5 minute film on. I have broken both alloy and carbon rims in the past and it's nice to know when things break, they don't go all to pieces. That's actually important to some people, and they focused on that aspect of the engineering - you don't have to value that, but I do.
  • 2 0
 @danielsapp: I'd love to see an article discussing and comparing FMEA methodology across different companies and component groups. If it's not the industry standard right now you'd expect more companies that actually perform it would brag about it. Safety sells well.

@privateer-wbc: Never said SC wouldn't break, there's no such thing as an unbreakable part. Just wanted to point out that it's interesting CB decided to appeal to customers this way, it's the first time I've seen any company do that. Bold move, let's see how that pays off.
  • 2 1
 @KondziuNS: I think it's just one note about the design of the wheels, and an important one. Especially for those who have had carbon failure.
  • 22 1
 So many haters! I have a set of these wheels and they are phenomenal. I've ridden carbon Rovals and Enves and the difference in ride quality was shocking.

If you like alloy rims you should keep riding them, but I've destroyed every alloy rim I've had and was constantly trying to true and bend them back into shape. A bent alloy rim will never ride quite right because you have to use uneven spoke tension to get them straight. I got quite good at re-lacing a wheel with a new rim, but I'd rather not do that if I don't have to.

Carbon wheels will never bend. You will never have to try to bend back the sidewall where it was bent by a rock strike, or use wonky spoke tension to get them true again. Yes, if they break they will need to be replaced, but with the way these are built you should be able to at least finish your ride until you can go home and get your rim replaced for free under CB's lifetime warranty. And BTW I don't know of any alloy wheels that have a lifetime warranty.

These carbon wheels are much lighter and stronger than alloy rims with a comparable width profile. Carbon can be tuned for stiffness in specific axis in ways that alloy can not.

In short, these are the best wheels I have ever ridden, alloy or carbon, and arguably the best wheels on the market. Of all the upgrades I have ever made, these wheels provided one of the most noticeable improvements. They are also very practical. I9 hubs are proven, and I will never have issues getting parts. Similarly, replacements for the standard J-bend spokes can be found at any shop and are easier to install & true than straight pull or some other proprietary spoke. The 28/32 3 cross spoke pattern is proven and if anything a little overbuilt. I don't anticipate having issues with broken spokes like I did with the Rovals I had for the last few seasons.

Yes these wheels are expensive, but I see them as an investment. With the lifetime warranty I will use them for many seasons and put them on whatever new frameset I get. Furthermore there are cheaper versions with cheaper hubs and spokes that will offer 99% of the performance.

Granted, the Zipp rims were custom laced with other hubs. I don't wanna blame the wheel builder because he does great work for all the local riders. Local guy also had a Cush Core installed so I'm not sure if that had anything to do with the failure. Kind of a freak accident, but after seeing how the Zipps just broke under normal usage, I'd personally stay away from them. Local guy isn't even a hard rider. At least he's covered by a lifetime warranty.

 That is an excellent question. I suppose there are probably a lot more costs associated with the volume of warranty claims on rims than frames, but then again, even if there are more claims on rims, the production costs are low enough that it takes some of the sting out of it for the company.

It would be interesting to compare the costs of open mold carbon frames to your scenario. LB/Nextie rims are $150-225 so they are nearly at parity with aluminum, and from what I recall of frames, it's the same situation, which would suggest that "name brand" rims have much more killer margins than frames.

 Glad to see them get a good review.

 @mtbsimon23: The only other set of carbon wheels that I've put any time on are the Bontrager Line 40s which I obtained as replacements for the Line Comp 30s that were stock on my 2018 Slash 9.7. (The OEM alloy wheels were not up to the abilities of the bike, sadly.) I put two rides on the Line 40s and found them too stiff for my liking, and they were a little too wide for the Grid 2.6/2.5 tires I mounted to them F/R - the front pushed in turns and the rear felt too harsh. Not terribly scientific, I admit, but I removed the wheels and set them aside and got back on the Crank Bros wheels. A few months later I unmounted the tires from the Bontragers and discovered a crack in each Bonti sidewall. Pretty disappointing. I have to wonder if the 40s were designed solely for snow/fatbikes and/or lighter riders*.
The ride of the Synthesis wheels has been really impressive. Control with the front wheel is confidence inspiring, the strength of the rear wheel has really sealed the deal. The width gives an ideal shape to my tires of choice (DHF/HR2 currently) so traction is never a problem. A lot of internet chatter has been posted here and elsewhere about the compliance of the front wheel and it's been misconstrued or worse (IMO) as 'flex' in the pejorative sense. I disagree and I think the only way to truly convey that is to demo these wheels if you possibly can.

*I'm 6'5" and about 235# on the bike so I'm not easy on equipment.

@castlecrew I am on the Project 321 hubs, and I had the rear wheel tension checked at my LBS in late April and found the tension was still spot-on.

 Which alloy wheelsets? Carbon wheels ride a good bit different from the start - take a carbon handlebar vs an aluminum one for instance. Overall though, I'd say that these would be closer to a good riding aluminum wheelset than they are to a lot of other carbon wheels - and that's meant as a compliment.

 @clink83: my Spank aluminium rims cost me about US$150 a pair. I prefer to spend my coin on durable hubs. Rims are just another wear item.

 @silentbutdeadly: that's 650 with DT 350 hubs, DT spokes and nipples, plus the rims. Unless you ride like a drunk gorilla those wheels aren't going anywhere.

 @clink83: good for you. But I just don't feel I'm missing out by not having carbon rims...Spanks on Hopes/Whites are just fine for this drunken gorilla thanks very much.

Between me and my mates we have destroyed around 8 LB carbon rims in the last 4 years! And all of mine, 3 off, have been when using DH tyres on their heaviest duty so called 'DH' rim.

Ive Still got one on the front that isn't cracked but I will be taking it off soon as personally i think they feel horrible compared to alloy rims.

A heavy duty DT swiss rim will easily out last a LB carbon rim.

For comparison I have been riding a Stans flow Ex mk2 on my 26" hardtail for 5 years and it has just given up after re-truing for probably the 6th time.

 @silentbutdeadly: I feel the missing out when it comes to climbing long durations on heavy rims in the Rockies... That's where it's noticeable! Been there done that.
  • 1 1
 @bohns1: I've never been to Canada and never ridden on carbon rims so I can't really miss what I've never experienced! Still like to ride in the Rockies though.

The Spank Trail Bite 295 rims that I use were cross shopped against the equivalent LB and Nextie hookless rims at the time...and the weight penalty to price equation on the rims alone meant the Spanks got the nod. Even the wheel builder was impressed with the value and build quality - enough to recommend them to other clients to this day.

 @silentbutdeadly: an AL rim would of failed under the same load that will kill a carbon rim. It's DH, you're going to break rims.
  • 1 0
 @silentbutdeadly: so basically you've never ridden carbon rims., but the aluminum rims that cost the same as carbon rims are better? That's a bit of a silly statement.
  • 1 0
 @clink83: my go to alloy rims (Spank bead bite trail 295) are roughly half the price of the equivalent LB carbon rims the last time I looked. And, whilst I know LB rims are good, I can't imagine the LBs are twice as why pay more?

When did I ever say I rode DH? I just ride XC in the rocks!

 @silentbutdeadly: I quoted the wrong person, sorry. I got my nextie rims for 110/rim, which is the price of a decent AL rim. Loosing half a pound in rotating weight while still getting a giant increase in stiffness and tracking makes them twice as good. I have hand built DT Swiss rims and Stans rims for roughly the same price, and the nextie rims blow them out of the water in every way. There is a reason people who can afford them buy them.

 @silentbutdeadly: umm less rotating mass.. The 27.5 spanks weigh in at over 1700g.
  • 1 0
 @bohns1: perhaps...but I tend not to notice or recognise that across all my MTB and gravel bikes.

And I'm running the 29" Bead Bite 295 rims... don't recall them weighing anywhere near that much. About 490 grams each and the wheelset they are in is custom and is built for a rider weight of 105 kg...

 @clink83: that's an excellent price for Nextie - I couldn't get close to that at the time. I think my rims come in around US$90 at the moment

But then I buy everything in AU$....

 I will not debate about quality or price, however with this type of product i’m more interested in warranty?

In which countries it will work? Turnaround time?

 I broke a rim going full speed down a chunky rock garden with pressure too low for my weight. They sent out a full wheel replacement the same day they received my broken wheel. All in I was out 4 business days. The experience was excellent.

 Our lifetime warranty on the wheels is valid worldwide. Currently any wheel that fails is returned to our development facility in Ogden, Utah. The expected turn around time is one week, from when the wheel is dropped off with the shipper, to being back in the hands of the rider.

 So expensive lol. A wheelset with spank rims, Hope hubs, sapim spokes and Maxxis rubber is cheaper than a single rim. We are one seems to be the way to go if you want carbon. Still expensive but that warranty softens the blow a bit.

 I'd like to know the difference between the Synthesis E11 carbon wheelset ($2400) and the Synthesis E carbon wheelset ($1700).

All I can see right now is 80 grams and $700.

 Just cheaper spokes and hubs. Besides the difference in engagement, you would probably not notice the difference.
  • 2 0
 @kramerica5000: That's what I'm wondering... if it's just spokes and hubs, seems like you could get the performance of these wheels for much cheaper than $2400!

 For the wheel building nerds; why would you want DH wheels to have longer spikes than the all mountain version?
  • 1 2
 Two reasons I can think of off the top of my head. The first being DH duty rims have a lower profile and larger ERD so that wind has less of an impact when you're jumping (spank rims and flow rims employ this method) and the second being that longer spokes mean a more compliant wheel.

I actually build DH wheels with the spokes on the low end of recommended tension for the rim, and it has a huge impact on how durable the rim is, i.e. you get a lot less dents, buckling, and pinch flats.

Just my two cents. I'm also interested to see what reasons there might be, as my reasons are pretty much from personal experience and just anecdotal.

 Weird, a bunch of people complaining about expensive carbon rims. Is the price of carbon rims new to everyone? Have I travelled back to 2012 in my sleep? May I recommend We Are One. Reasonable price for carbon, sourced and made in Canada, and lifetime warranty. I used to go through at least one alloy rim a season. Since switching to carbon seven years ago, I’ve cracked one rim (and it was completely my fault). How many years do they need to last before they’re worth it? Run the numbers.
  • 2 3
 I cracked an Enve M70, by the way. A few years before We Are One came along.

 Is there a shipping flatrate during the lifetime waranty?

 If you experience a problem and need to use the warranty, we will cover all shipping costs incurred.

 It will all be over soon enough. Back to Al frames and wheels. If it aint broke...go back to it.
  • 4 3
 Nice, they cost as much as my complete Canyon rig, including a Syntace W30 wheelset, which holds true after 4 years of use.
  • 4 5
 You can get a Newmen wheelset for 700€ which weights 1650-1700g.

Why on earth would you buy something 4x the price?
Carbon wheels are so stupid expensive and do nothing better
  • 3 1
 Why not go with an aluminum front wheel and carbon rear?
  • 1 2
 no mention of rim weight. $2,399 wheelset when you can build competitive stuff with better hubs for a grand.

this plus the e-bike content really makes me question PB's Core-ness, though I'm probably late to that party.

 Hum wrote this morning about waiting a review for Hunt trail mountain carbon wheelsets aaannnd... disappeared!! So I said you can afford two of these wheelsets for the CB cost! On paper it's exactly the same stuff!
  • 2 3
 I'd like to see a comparison with more sensible priced wheels.

Tested to destruction next to a £300/£400 wheelset. Because 700 quid for a rim is a f@&$ing joke!
  • 3 0
 One of the German magazines did that (not with CB wheels, though). They found that on average, carbon rims were a bit stronger, given similar weight.

They also found that a really well made aluminium rim (Newmen) was stronger than most carbon rims and only one out of the carbon group was substantially better (= worth the price).

 @Ttimer: it's what I suspected. I've allows gone mavic and hope, they've never let me down and I'm a sadist with bikes.

 @Ttimer: "strength" is a poor metric of value outside of DH. Carbon rims are better performing in weight AND stiffness, which is more important.

 Crank Bros Meeting:
Engineer: "Guys, our products always break, it's affecting our reputation and sales. We should do more testing and design our products to be more durable."
PR guy: "That sounds like a lot of work. How about we call it "Safe Failure Mode", pretend we made stuff that way on purpose and add $100 to the RRP"
