Strengths:    Looks good, fully tubeless & no need for rim tape. Spokes are easy to replace without having to remove tyre, rotor or cassette.

Weaknesses:    Spokes keep breaking. Replacement spokes are expensive. Rim tab (which connects to spoke) completely tore out. Doesn't work too well after one spoke breaks.

Bottom Line:   
I love the look of these wheels, but the spokes have let me down too many times.

I do a lot of riding. Perhaps it's because there aren't as many spokes as a normal wheel, but these wheels seem to be a magnet for sticks. I've lost count of the number of times I've broken spokes on the rear wheel. Once the spoke even ripped out of the rim tab without breaking.

On a 32 spoke wheel, if you break one spoke you should still be ok to ride as there are plenty more spokes to take the strain, but on this 24 spoke wheel, once you break a single spoke the wheel goes out of true, and it places too much tension on the other spokes. You have to replace broken spokes right away or you'll end up breaking even more spokes due to increased tension.

This means you must carry spare spokes. And replacement spokes are very expensive.

I like the envious looks I get from people who look at the wheels on my bike - it looks cool.

BUT these wheels don't have the reliability I need.

Strengths:    Light weight, tubeless ready. Love the dual QR skewers

Weaknesses:    can't think of any

Bottom Line:   
I built these up, added a new cassette, rotors and chain. I have not had any kind of an issue with these. I had some questions (setup related, not quality related) and CB was able to help without having to wait for ever for a reply.

Strengths:    look sick, nice quick release

Weaknesses:    flimsy, bend easy, a joke to true up

Bottom Line:   
I rode these wheel set 1 season before the rear wheel was so bent it needed to be replaced. I sent it back to C/B and the technician called with a quote of $150, after how much I spent for the wheel set and the inconvenience I was not spending another penny, so much for the warranty. I purchased some Mavic 819's w/ Hope hubs and have not had a problem since. I definitely don’t recommend this wheels set for cross country riding, brittle.

Strengths:    Tough for the weight, look nice, easy to set up tubeless, and are fairly light.

Weaknesses:    Original rear hub

Bottom Line:   
I have had these wheels for the past year and have used them for aggressive XC and trail rides. Crank bros replaced the rear hub body and I have had zero issues since. I have burped a few tires off on rocky descends, but otherwise they have preformed really well. I would recommend these wheels to anyone looking for a nice set of trail/XC wheels.

Date Reviewed: April 10, 2012

Strengths:    look snazzy. light.

Weaknesses:    after less than one year, I hopped off a small embankement (1 ft) to find the front wheel was completely farked.
the guy at the bike shop (Velofix - they are awesome) said that he has heaps of problems / complaints / returns and basically they are an overengineered unreliable part. I would have to agree!


Bottom Line:   
good to look at, unreliable and overpriced and soon no-one will want them. If Paris Hilton were a bike wheel this would be it.

Strengths:    Style and function all in one.

Weaknesses:    I have a hard time regulating myself on my XC bike... I have a tendency to forget that I'm not on my DH bike, and the wheels are the first thing to pay for it. I had a hard time keeping them true. I'm in the 200lb range and an aggressive rider, so I really can't blame the wheels.

Bottom Line:   
Great wheels if you have self control.

Date Reviewed: July 7, 2011

Strengths:    Light, Stiff, easy to service/maintain, UST tires mount and seal easily

Weaknesses:    Lots of seal drag on the hub bearings. Some cassettes rub against the rear hub flange (My 9 speed XT does); I contacted CB and asked about this and they are aware of this, they also told me to use the shim rings included to mitigate this issue; however, for a $950 retail set of wheels this is just not acceptable. My wheels came with the old hub design, CB was very prompt in sending me a new re-designed replacement hub body.

Bottom Line:   
This wheels have been good to me and overall have performed the task intended. In hind sight, I regret changing my Crossmax's for these set. They have potential to be great wheels, but have some issues to be addressed first.

Strengths:    Look the dogs nutts! Super Stiff, Responsive and light!

Weaknesses:    None what so ever!

Bottom Line:   
I was also concerned about the bad reviews, but heard that the freehub had been re-designed, I am told that the hubs are now made by Formula. I've hammered them in loads of races and training rides without any problems, I can only assume that this is because I have the new version Cobalt XC's. I highly recommend them.

Weaknesses:    bad surprise on the trail = freehub problem (threads wear-out)

Bottom Line:   
Disapointed with the quality of this product and now worried about using the wheelset and getting a bad surprise during a ride...

In general Crank Bros gave me a good impression as I use their pedals and never had problems.

Weaknesses:    none yet...no not even with the free hub!

Bottom Line:   
I dig these wheels! I have had no problems at all, stay true (but if/when you need to these wheels are easy), track unreal with no flex...just point and go! Heard about earlier problems with the free hub but mine and my buddies (he's had his for over a year) have had not one problem. BTW, they look awesome!!

Date Reviewed: January 12, 2011

Strengths:    Pretty, cool design, good pickup

Weaknesses:    Form over function - early problems with the free hub assembly (which they redesigned in 2009 - though my buddy has a new pair of cobalts and it failed anyways), dents way too easily, Crank Brothers slow in agreeing to fix stuff (according to my LBS who has to deal with them)

Bottom Line:   
Looks pretty, but stick with something tried and true... at least for now. These wheels are still new to market and maybe will get better in time

Strengths:    lightweight, accelerates like a demon

Weaknesses:    I'll give you one guess

Bottom Line:   
thought the hub problem was just a small percentage of cobalt owners when I bought it. then the hub had to be fixed twice in the past 5 months. the shop was kind enough to service and replace the cassette body for free, but I don't want to be in a situation where I'm in a trail again and the cobalts fail again.

will replace this soon.

Strengths:    looks weight

Weaknesses:    freehub, soft alloy rims

Bottom Line:   
Sorry guys believe all the negatives, the freehub is useless and badly executed also the rims ding Very easily. they do stay truish though under some fair trail riding, but hey theres no point in it being round if you cannot pedal it because the ratchet pawl has blown again. 8 months of ownership, 4 re builds (yes with the right grease) and one new freehub body, but still still they go bang and the hub slips every 5 k's. Importer says "for race only" funny how no one else says that.

Bottom Line:   
Sorry but please believe the negative reviews! I love the look, design and intention. I hate the execution, and the importers line that "they are race wheels only" is rubbish, 4 hub rebuilds, and one new freewheel hub in only 6 months occasional riding, then a pretty poor importer (crank bros company support is ace just somewhere in between it them and me it vaporises)
