Strengths:    Light, strong, stiff, sharp looking.

Weaknesses:    Junk

Bottom Line:   
Excellent when they work, but they don't work long. I had a drive problem with the first set of Cobalt cranks, delaminated the second set in less than three years and two thousand miles of 70% dirt roads, 30% rocky single track. I'm big (200 lbs.) and ride hard. I love air. I just split the bottom bracket on a steel Schwinn road frame. I worked the cranks hard. But not hard enough to justify this kind of problem with this expensive a crankset.

Crank Brothers was cool with the stripped ISIS, but I don't trust these cranks enough to warranty them again.

Date Reviewed: May 17, 2011

Weaknesses:    Poor Quality - I was told that this set had a problem with it de-laminating, but was told by Crank Brothers it is under warranty for 5 years and they would take care of me. I rode this for one full season and then it started to de-laminate. Crank Brothers is not replacing, nor standing behind what they sell. They knew of this problem, yet still sold it to dealers instead of pulling if off of their shelves.

Bottom Line:   
I had believed that Crank Brothers had good customer service (based on other reviews) and would take care of any problems, they have not. I was told by the service manager, not only would they not replace it (because they don't have anymore), they would PRO-RATE based on what I paid for it - not the retail value. And would 'replace it with other products for max of $50 and not another set (retail value $400)! Bottom line, there are problems with products and it is how the company stands behind them, Crank Brothers did not, nor will stand behind what they make and sell. This will be the last Crank Brothers product I ever buy.
Buyer beware, if you buy a Crank Brothers product, know that even if there is a 'warranty' they will prorate (that is not in writing) based on what you paid, and if they don't have anymore of that product, you are screwed!

Strengths:    Light, stiff, stylish??

Weaknesses:    None.....yet?

Bottom Line:   
Really stiff and light, an excellent upgrade. This for me has been a great crank, one of my favorite upgrades. And I pound these cranks, I'm 6' 190lbs, FR and AM rider. I know all the de-lamination issues... I called CB and told them I wanted these cranks but was unsure of the quality after all these delam problems. They assured me I would not have this problem. As such, for 169$ these were a steal. My situation is unique, but still... excellent thus far

Strengths:    Light, Stiff, Looks fly

Weaknesses:    Delamination on both the drive and the non-drive side arms

Bottom Line:   
Considering thier name is "crank brothers" you would think that they would manufacture a quality crank. First of all, they should name the "cold fusion" for what is actually is: Glue, and poor quality at that. for the time I rode the cranks, they performed great, the cranks coupled with he Ti BB made for a super smooth ride. I'm on to my 4th set of these guys now (thank god for 5 year warrantee!) and the same problem keeps arising. first the non-drive side split, and then the drive side, and then the non-drive again, and i'm waiting to see what happens to this next set on the way.

Strengths:    They were super stiff

Weaknesses:    They broke on me in a week, and i never got a new set of cranks back. Therefore I'm out 500$$$$ in a week.

Bottom Line:   
I'll never get anything again from crank brothers I'm out 500$$$$ for nothing. If I can even get my old broken pair they would look really nice on my wall.

Strengths:    Looks great!!! Stiff and Crank Bros is a great company to work with.

Weaknesses:    Reliability.

Bottom Line:   
I delaminated the non-driveside crankarm after three rides. Granted, I am 210lbs and it's a 29er singlespeed, but I wouldn't expect a crankset this expensive from a company like Crank Bros to break that quickly. I took it to the shop where I bought the bike and mine was the second delamination they've had (both on SS bikes).

The bike shop said that Crank Bros told them they had a batch of bad glue from their supplier that found it's way into production and hence the rash of delaminations. The good news is that according to the shop, Crank Bros is a fantastic company to work with and everything will get taken care of. If it's not taken care of straight away, I'll re-review.

During the two and a half rides prior to delaminating, the crank was great! Seemed very stiff with good energy transfer.

Strengths:    Looks great and cometitive weight, plus the bb seal/gaskets really work.

Customer service is second to none.


Weaknesses:    Reliability!

Bottom Line:   
Quality/reliability sucks! I broke my first set after one month of mild xc and road riding (180lbs rider), my wife broke hers after same amount of time (110lbs waif). Now my second set sounds like it's delaminating as well (or the bb is going out).

I really like Crank Brothers products, and for the most part have had very good expirince with them. This product has some issues! In the end the Customer Service will try to make it right.

It sucks for me b/c I have roughly the cost of a starter bike in cranks and bb's that are not worthy of the premium price I paid.

Date Reviewed: July 20, 2007

Strengths:    The cranks look great and are light weight and shifting was not an issue.

Weaknesses:    The bonding between the stainless and aluminum cracked on the non drive side. Looking at other reviews durability seems to be an issue. I'll probably stay with Shimano XTs from now on.

Bottom Line:   
They will be good cranks if the durability issue is resolved. I expected better quality from Crank Brothers and for cranks in this price range.. They would probably be ok for the lighter riders but Clydesdales should stay clear.

Strengths:    Looks awesome, great stiffness.

Weaknesses:    Cracked the non-drive side during a 12 hour race on an easy cross country course. I weigh 170lbs. Going to see how this warranty works but I am worried. Hopefully this is isolated?

Bottom Line:   
I hope this is a one time thing, cranks are not something I want to worry about breaking.

Strengths:    Beautiful and light. Would consider them again if this is an isolated case(see below).

Weaknesses:    Broke after one year. Arm cracked thru at pedal bolt and also twisted a few degrees. Truvativ rings suck.

Bottom Line:   
Will call their customer service today. I'll post a new review based on the warranty and claim handling process.
I hope things work out, these weren't cheap.

I was looking at the design spec of these cranks only to realize that they are very different from all the other high end cranks on the market. They bond high grade aluminum to stainless steel to achieve their hollow design. It would seem to me that if anything, this would result in failure points ... Read More »
