$160.00 Favorite Ride: K2 race in New Zealand Summary: Rubbish!
These cranks came OEM on my bike. In the five months I've had them, I've done 8 or 9 rides over 10 miles, and probably 30 rides to the shops. I've had the following problems.
1) pedal wasnt put in tight enough at the bikeshop, and within 5 miles of the shop it'd worked loose and destroyed the left crank. The shop gave me a new one.
2) the left crank keeps working loose. We're talking between 5 and 15 miles after being tightened, it'll be loose. When it's loose it rocks about on the axel and is wearing the splines on the crank arm out. So now I need another left crank, although I dont think I'll bother, as I still can't go for a ride without taking along an 8 and 10mm allen key, which are bigger than any on multitools.
I will be replacing these with shimano ultegra or dura-ace. The shimano system uses a pinch bolt to secure the crank arm, a system that actually works ... set and forget, none of this stupid tighten before every ride stuff that is Bontrager Race. Strengths: None. Seriously this crank has been designed/built too cheap to work, and a crank that doesnt work is useless. If it flexed or something, then I could say it's fine for weaker riders, but the cranks not staying on the bike, just useless for anyone Weaknesses: As in summary, the retention system for the left crank arm just doesnt work. Similar Products Used: Shimano 105 (9spd), Ultegra (10spd), XT 750 (mountain bike), Sugino, XT (old square taper), Deore (old square taper).
