Strengths:    Looks, weight, ceramic bearings

Weaknesses:    Soft metal on the crank spindle, otherwise they would be great.

Bottom Line:   
I just removed my second set of K-Force Light cranks because of play in the bottom bracket. When I first installed the cranks I followed the directions correctly and everything seemed fine. Then, during a regular maintenance check, I noticed that there was a slight amount of side to side play in the cranks. I checked the crank bolt for tightness, but it was at the correct torque. So then I started really keeping an eye on it and after one year the side to side play was so bad (even though the crank bolt was tight) that I removed the cranks and checked the bottom bracket cups. They were tight, so I started looking further into it. I noticed that while I had the cranks and bottom bracket off of the bike that the bearings were loose on the crank spindle. I noticed some wear on the spindle where the bearings ride. I contacted FSA about this and they said they had never heard of this before, but they sent me a new set of cranks. The new cranks went on fine, but developed the same problem after a month or two. I have since removed the cranks and BB and replaced with Shimano Dura Ace.
I would not recommend getting these cranks.

Strengths:    Smooth ceramic bearings, smooth shifting and stiff rings. A lightweight setup: 700 grams for crankset and bearings put together. Looks good with my Look bike.

Weaknesses:    None that I can find.

Bottom Line:   
I have the carbon compact crankset exactly as pictured above, with 34-50 chainrings. I believe this is the third generation of this crankset. Neither myself nor anyone I know has had any problems with this crankset. The ceramic bearings are smooth as silk; the 7075 CNC chainrings are plenty stiff and the pedals attach securely. I replaced a DA 7800 double crankset with this FSA carbon compact crankset. The compact 34-50 rings are great for all day rides in the mountains and there is still plenty of gear for racing. My FSA 50-11 high gear is actually a higher, stiffer gear than the 53-12 gear I used when I first started racing.
