Strength:

Fairly light. The new design is cooler looking than the one I had.

Weakness:

Design flaw created that weird issue. It happened over and over, we'd get it slightly better, and then it'd start happening again. You just can't have equipment on your bike that isn't reliable.

After a race the Thule rack that my bike was secured to had a fatal flaw and my racing bike went crashing into the ground at freeway speeds (note: it was pure product fail but Thule was terrible dealing with around compensating. I will never buy a Thule product again, and neither should you). The crankset was destroyed just like the rest of it. I had a K-Force Light before, and my bike shop suggested saving a few bucks and going with this slightly heavier model. Works for me.

For the most part the crankset was totally fine, but from the get-go I had this one weird issue. When I went to shift from the big chain ring to the little chain ring, the chain would move over but then not "set." It would just float on the top of the teeth of the small ring as I pedaled. I'd spin and try to get it onto the teeth so that I could actually pedal, but I'd have to get off and manually push it over. Crap.

I had the shop work on it a number of times as both of us thought it was just a matter of dialing it in. Unfortunately it wasn't; it was essentially a miniscule design weakness. As time went on they saw more and more of this situation with FSA cranks. After this happened in a race and took me out (luckily not crashing though), I took the cranks off and replaced them with a bombproof Ultegra set. I won't be buying FSA cranks again.

Strength:

Lightweight

Weakness:

None

Very light, stiff with great power transfer. No sense of loss of power on hills or sprinting from standing start. Shifting with Ultegra 6700 FD and chain is smooth and quiet. Grahics look awesome. 53/39 rings
