FSA: K-Force Light Crank

Construction:
FSA K-force Light CrankThe K-force group includes a monocoque carbon crankset: using their newest hollow carbon construction technology. It creates a completely hollow crank arm with a distinctive "thatched" or woven appearance and high gloss finish.

These FSA cranksets have chainrings fabricated out of AL7075 using full CNC technology for added accuracy, with a black face and a silver lasered logo. Even the chainring bolts are an AL7075 Torx T-30 alloy on the FSA K-force light crank to create the ultimate light weight carbon crankset.

FSA BB (bottom Bracket) K-force Light CranksetBottom Bracket:
The BB, to match this FSA power drive crank arm is equally impressive. It uses oversized ceramic bearings and an integrated 24mm CrMo Spindle. This is what differentiates the "K-Force LIGHT Crank" from the regular K-force crank.

Research into the use of ceramic bearings suggests a 5 to 10 times longer life expectancy than its steel bearing cousin typical of most bb. FSA's ceramic bearings allow greater power at the drive crank arm with the use of special lubricants and low friction seals to reduce rolling resistance. This is the biggest different between the K-Force light crank and their cheaper SL-K line of FSA cranksets.

Red anodized alloy external bearing cups hold it all in place.
