What is it: The
Easton Haven Carbons are a no holds barred attempt to create the ultimate all-mountain wheelset. They are built using a 375 gram, tubeless carbon fiber rim, 24 Sapim spokes per wheel and eye catching hubs that spin on ceramic, sealed bearings. Total weight for both front and rear wheels adds up to an impressive 1450 grams - lighter than many pure cross-country racing wheelsets. With an eye popping suggested retail price of $2300 USD, Easton knows that these premium wheels will not be for everyone, but those who do decide to spend the money will have piece of mind knowing that they come with a
2 year, no questions asked warranty. You'll be looked after if the worst does happen, no matter if that's a jump gone horribly wrong or backing over your wheels with your car.
Easton's 1450 gram Haven Carbon wheelset has been designed to be put through the ringer on all-mountain and trail bikes by aggressive riders.
Easton Haven Carbon details:
- Intended use: All-mountain/trail
- Uses 375 gram, fully sealed, UST, carbon rims
- 24 Sapim straight pull, double butted spokes, 3x front/rear (all the same length)
- Axle options to fit QR, 15mm and 20mm forks, QR and either 135 or 142mm thru-axles in the rear
- 21mm internal rim width, 26mm external width
- 36 point gear ring/3 pawl hub for 12 degrees of freehub engagement
- 1450 gram wheelset weight
- No questions asked 2 year warranty that covers everything, including rider error
- Haven Carbon 29'er wheelset available as well
- MSRP $2300 USD
The details: While the exquisitely machined hubs are certainly striking, the main talking point with these wheels is undoubtedly the 375 gram carbon fiber rims. In order to create a carbon rim capable of meeting their ambitious impact strength tests Easton brought Sayeed Syed on board, an engineer with extensive experience working with composites for military applications. The outcome is a high modulus polyethelyne (
HMPE) composite material, held together by an exclusive resin, that Easton says is far better suited to the abuse rims go through than a more standard carbon layup. The rims also have a matte gray finish to them, forgoing the use of a purely cosmetic carbon weave finish that would only add weight. Just like the aluminum Haven's, the carbon version has a fully sealed rim bed that doesn't require a rim strip when used with standard tubes or tubeless setups. Easton accomplishes this by using inserts at the rim that the nipples thread to. The aluminum nipples have threads on the outside that thread into the insert at the rim, and on the inside that the spokes thread into. The threads on the outside of the nipple are left hand thread, while the spoke threads are right hand thread, allowing the carbon Havens to be trued using standard tools and techniques. The rim is also UST compatible for quick and secure bead seating, even at low pressures, and they come complete with UST valve stems to make setup easy.
At the center of the 24 straight pull Sapim spokes you'll find a set of impressive looking hubs, complete with ceramic, sealed bearings as stock from Easton. The drive side hub uses a three pawl aluminum freehub body that, while not quite having the near instant engagement of some of the competition, seems to freewheel smoother - a selling point for many riders. The front hub can be had in two flavors: one that fits both 9mm QR and 15mm thru-axles, and another designed specifically for 20mm axles, while the rear can be converted to fit standard 135 mm QR, as well as 135 mm and 142 mm thru-axles. You should have no worries when upgrading your frame or fork down the road because the Carbon Havens will bolt right up. The hubs fit standard 6 bolt discs - there is no Center Lock option.
The fully sealed, UST rim is manufactured using an exclusive carbon and resin mix that Easton says has incredible impact strength.
Performance: What would you expect from a $2300 USD wheelset? Nothing but the best as far as performance and reliability are concerned, naturally. And the Haven Carbons come close to that in both categories. The wheels are staggeringly light out of the box and in your hands, almost unbelievably so (
the front wheel alone weighs less than many all-mountain tires), but it's on the trail that that lack of rotating heft really comes into play. Having spent plenty of time on many all-mountain wheelsets in the 1600 gram range I wasn't expecting to be blown away by the roughly half pound weight difference between those and my new carbon rimed wonder wheels, but the contrast between them was immediately noticeable. The result of the wheel's light weight is a bike that not only accelerates fast, but one that is also a lot more lively on the trail. This was especially evident at slow speeds where you can't use the bike's momentum to help you, whether it was getting through a tricky, technical section of trail or just playing on some rollers, the Haven Carbons actually made the bike easier to ride.
Sure, the Haven Carbons are staggering light given their all-mountain intentions, but building up a lightweight wheelset isn't actually that hard - the trick is to add stiffness and reliability into the equation as well. The 24 spoke per wheel Haven Carbons are not just stiff, but actually manage to make my heavier, aluminum rimmed wheelset feel as if they were quite low on spoke tension. I tend to ride my 6" travel bike as if it had much slacker angles and more suspension, pushing it harder than it was really intended for on many occasions, but the Havens were more than up to the task. Despite plenty of sideways action and probably more abuse than Easton intended them to be put through, the Haven Carbons are still as perfectly true as the day that I took them out of their box. I tested a number of different tires during my time on the Carbon Havens, using some with low enough air pressure that hard rim strikes were routine, and the carbon rims proved to be far more rugged than any other aluminum option that I've put time on. I am confident in saying that any aluminum rim that I would have had mounted during this time would now be sporting multiple dents and dings, but the carbon rims used on the Haven wheelset have come through unscathed. The wheels have also held their spoke tension throughout it all. While I knew that the Haven's carbon rims were robust - this was evident by Easton's confidence in them - I am still very impressed with how they have shrugged off any and all abuse.
The stunning hubs rotate on ceramic bearings and can be converted to fit virtually every axle standard out there.
Unfortunately, I did run into a reliability issue with the Haven Carbons far earlier than I had expected. After just a dozen rides on them I discovered that the rear wheel's bearings had become slightly loose and required a small amount of tension to be added via the threaded preload collar - not ideal, but at least it is an easy fix. Or so I thought. After adding only the slightest amount of preload, just enough to remove the play and no more, the ceramic bearings quickly became notchy, slow rolling and needed to be replaced. Easton suggested that there is a good chance that I unknowingly rode the rear wheel with the bearings slightly loose, fatally damaging them in short order, after which removing the bearing play only made them feel terrible. Fair enough, but I would hope that the wheels would have gone much, much longer before needing any sort of bearing adjustments. To make matters worse, my near new bearings that Easton replaced for me have just now needed to nipped up again, even though it's only been about two months. Our aluminum Haven wheels, which use the same rear hub, but with non-ceramic bearings, have also required bearing preload adjustment far too soon. I would be disappointed even if these were a $500 wheelset, but with an MSRP of $2300 USD, I, along with most consumers, would surely expect to have zero issues.
Pinkbike's take: When talking about all-out performance the Haven Carbons have no peers. Not only are they lighter than many cross-country racing wheelsets, they are also stiffer than other wheels that weigh a full pound more. While I was let down by bearing issues in the rear hub, there is no denying that the Haven Carbons brought an element of performance to my bike that wouldn't be possible with a more standard aluminum wheelset. The bike simply rode better: it climbed and accelerated faster, was more playful on the trail and also felt quite a bit more rigid thanks to the wheel's impressive stiffness. Are they worth the $2300 USD asking cost? That's a big price to swallow, especially considering that that amount of money can buy a very decent bike these days, but next to upgrading to quality suspension on the front and rear of your bike, these wheels are possibly the biggest game changer that you can purchase. Keep in mind that price is relative - anyone unfamiliar with mountain biking would gasp at the thought of spending even a few hundred dollars on a set of wheels. No, you don't
need the Haven Carbons to go fast on the trail, but they sure do make it more fun.

What do you make of Easton's carbon rimmed wonder wheels? Let's hear what you think - put those thoughts down below!
They added an extra 0 by mistake and said $2300 USD wheelset, not $230.
Actually...hang on...... NO !!... FOR REAL !?!?!?
How about a ratio of total spent on bikes in the last five years to annual income.
I got 1:5
People "invest" thousands in stuff like Tune or CK hubs, Edge/Enve components, buy 400$ pedals, 100g lighter than ones for 50$
would you ride those wheels on a bottlerocket?...i would be afraid on mine...
WHY ???
why would somebody really spend that much money just to save a few grams
(if your really that much of a weight weenie then maybe you should just be a road cyclist)
and why does everyone love carbon so much ???
my experience with cf has resulted in pure failure
(very pricey parts shattering or cracking after a hit that the part i originally had (that cost a third of what the cf did) would have barley been scratched )
have fun neg proping me ... i really dont care
anyone who has ever used cf for any hardcore riding will understand what im saying
As for using carbon for "hardcore" riding, I have to disagree with you!
My mechanic is one of the few dealers of Santa Cruz in Belgium. He spoke with Cedric Gracia and Steve Peat at a race in Scotland and the only thing that lets them down on their carbon v10's are the carbon rims. Now here's my opinion:
If the frames can hold the pressure and abuse that professional riders throw at them, then you have no reason to fear using carbon for anything. Nobody here can keep up with those riders, nobody has better technique. They manage to crack Enve's rims, riding about 50kmh or 30mph over rock gardens on a bike with suspension plusher than Jenna Jameson's mattress and tyre pressure lower than the one of the average car tyre. OF COURSE THEY CRACK!
At 2300$ a set, only people with money can buy them. Smart people, who can ride and know some technique will buy them, ride them for what they are meant and keep them spinning. Other people, will buy them only to show off and they will abuse them in some cases. Those last people are the ones who'll end up like Svard75 mentionned above.
I ordered a set and I can't wait to use them for AM, not DH.
@RobbyBriers - I know what you are trying to argue here, however ask these pro riders how long they keep their carbon equipment for.
Whilst not a Carbon Wheelset, I do have a Carbon canoe ( Swift Winisk - Carbon-Kevlar layup)
and an older plain Kevlar boat ( Swift Kipawa ) Regarding the Winisk - This thing sees a lot of sun - like days on end being paddled thought water with the sun baking. There are no issues with de-lam due to UV exposure in the boats I or people I know have. Now going back a few years - there were some issues with the early resins - but that is long in the past. These things are not babied, they hit rock, get portaged for miles thru the bush - getting dropped, banging trees, get used as tables and shelters as well as carry hundreds of pounds of gear and people. I have had to replace wood trim and structural pieces but have never had an issue with the Carbon layup.
I can not see Easton or Enve using a carbon / resin system that would have UV or de-lam issues.
If they had to build a new test machine to break their new carbon bars, the wheels are probably in the same catagory as well. ...and the two year warranty, well, alot of riders go through a set of rims a year not racing. So if they feel they can back them up for two years against anything then they should be good enough for us everyday hacks. I don't think they will self-destruct on two years + 1 day.
either way, time will tell.

Like your wheels, my aluminium Havens have notchy bearings in the front hub. Would that also be covered under warranty?
Should I order up a set or rear bearings just to anticipate the rear hub also frying?

This would be similar to you posting a photo of a cut tire on a review of the same model...
The only reason we are so affraid of CF is because we see what happens to roadie gear - and as everything with roadies, it's wroooong and all their exports to MTB, screws it up for all of us. It's good we start to have more and more stuff of our own. It's like comparing golf clubs to baseball bats...
Loads of riders, including myself, have detonated aluminum wheels in an instant. Like I said, your photo in interesting but it doesn't tell us the entire story =)
A bicycle component explodes in following circumstances:
- a PRO or half PRO rider during a race practice or race run
- a brainless, fearless Rookie in any situation
Every equipment used accordingly to it's purpose ridden by riders of skill and self preservation instinct level in between those stated above is safe. At least as long as they don't put it into situation where anything else would fail
You can find thousands of pics of broken DH aluminum wheels. How many Stan's XC wheels could make a single DH run without blowing up? It seems for the weight carbon is WAY stronger. There is simply no comparison. Maybe we should go back to steel rims or the really old school wooden rims LOL!.
I have a set of non branded carbon rims on my Mojo SL and they are the stiffest, lightest, strongest wheels I have. They take way more abuse than my previous aluminum AM rims which were 150-200g heavier each. They take abuse like a true DH rim, but at almost 1/2 the weight.
The MOST IMPORTANT performance component on a bicycle is the wheels. You would be far better off with a 1-2 pound heavier frame for under $1000.00 with these wheels than a $3000.00 frame with cheaper wheels. Smart spending rather than flashy spending.
- A pair of Nobby Nic 2.4 SS EVO = 1540gr
- Nomad carbon frame + seat clamp + chainstay protector + E-thirteen Heim 2 + Fox Float RP23 + Rock Shox Reverb incl remote + Fizik Gobi XM K:ium = 3720gr
- 2012 Fox Talas 160 Factory + Easton Haven 55mm stem = 2310gr
Rest is inc.
Supposing that the wheels do come in at 1450gr, the total so far is a little more that 9kg. I don't believe that the Haven carbon bar, a Cane Creek 110 headset, point one racing pedals and a full 2x10 XTR group (incl brakes and XT rotors) will only weigh 2kg.
cassette (11-34t) = 255gr
brakes = 475gr
shifters = 225gr
derailleurs = 310gr
crankset (28-36t) = 645gr
chain = 260gr
That already is 2170gr without outer cables / BB / rotors. Still need the bar 175gr-ish, the headset and the pedals... and the grips! haha
Even without dropper post, it would still weigh 11.5kg or so. Under 11 it wouldn't be enjoyable i think...
