Strengths: not too heavy. nice lookingWeaknesses: noodley, isisBottom Line: these cranks flex alot. it drastically decreases efficiency on climbs and acceleration. left crank arm fell off(bolt loosened up) in a race. happened to someone else with the same crankset less than a mile earlier in the race(first lap). i know several other people who have had the same problem, and i've had the same problem with every set of isis cranks i've run. never stays tight after that. switched to the shimano lx hollowtech cranks and noticed an immediate and significant increase in power transfer. i ran the lx's on my other ss29er for over a year with zero issues, and i expect they'll provide me the same worry free performance on this bike. do not buy these bontrager cranks, and if you purchase a bike with them installed, change them at your earliest convenience.

Strengths: It's there when you buy the Rig.Weaknesses: Everything.Bottom Line: This crankset plainly sucks, I just snapped mine after ~1600 miles of mild xc riding. At 5'5 and 165 pounds I'm no clyde and this should never have happened.

Strengths: Light, Single Speed SpecificWeaknesses: Stripped lock ring after 4 months of use.Bottom Line: After about 4 months of use, the lockring holding the sprocket spider stripped. After 2 months, 6 bike shops, contact with Fisher, Bontrager, and Trek I have not been able to get a replacement. I am done and bought a replacement. What ever happened to customer service and standing behind your product?

Strengths: Looks, priceWeaknesses: Strength weight.Bottom Line: Over all, not bad for stock cranks. They look awsome not too heavy and cheap to replace. I used these for just under a year all over eastern, pa. Right away I noticed a good ammount of flex from them, but decided to deal with it (not that big a deal for a "fun" bike. I managed to bend the right crank arm after 9 1/2 months. If you can find these for $100 or less go for it.
