Chainrings: 34 x 50
Weight: 630 g.
English BB cups included
The K-Force Light is another advance in performance and weight savings, representing the third generation of composite crank design. Constructed with ultra high-modulus carbon and a minimal use of aluminum components, the K-Force Light is molded with a removable bladder to allow maximum compression of the carbon material with the lowest amount of void areas. This results in high strength with minimal material. The hollow crank arms, featuring an internal I-beam, give the crank high torsional and lateral strength while ceramic bottom bracket bearings deliver a significant reduction in bottom bracket friction and weight while extending service life.

Chainrings: 34 x 50
Weight: 740 g.
BB cups included
The SL-K Light crankset uses FSA's I-Beam construction for some serious weight savings. Manufactured using compression molding and uni-directional carbon fiber, this crank features hollow, oversized monocoque crankarms and spider for super-stiff, no-flex performance. Standard MegaExo stainless steel cartridge bearings. CNC-machined aluminum rings are fitted with alloy Torx bolts. 170, 172.5 or 175mm. Includes English threaded bottom bracket.

Dura Ace 7800 Bottom Bracket sold separately
The Dura-Ace 10 speed crankset combines race-proven, hollow-forging technology with an integrated crank set and bottom bracket radically increases efficiency while decreasing weight. Dura-Ace Hollowtech II allows the bottom bracket bearings to be spaced wider apart (outboard bearings) and the axle and bearings themselves to be larger. The net result is a more effective load distribution, increased rigidity and stability and longer service life.
Lengths: 165, 170, 172.5 or 175mm
Chainrings: 30 x 39 x 52
Weight: 750 g.
Dura Ace 7800 Bottom Bracket sold separately
The Dura-Ace Hollowtech II crank and bottom bracket combines race-proven hollow forging technology with the integrated crankset and bottom bracket. Weight is reduced and efficiency has been radically increased. A combined FC/BB weight reduction of 30 grams has been achieved. In addition, Hollowtech II allows the bottom bracket bearings to be spaced wider apart (outboard bearings) and the axle and bearings themselves to be larger. The net result of course is a more effective load distribution, increased rigidity and stability, as well as longer service life.
The iconic Hollowtech II hollow forged crank has always been a benchmark for strength to weight performance characteristics. Lengths: 172.5 or 175mm
Chainrings: 39 x 53
Weight: 725 g.w/ Bottom Bracket
Dura Ace 7900 Bottom Bracket sold separately
The perfect platform for a crank intended to be used at the highest echelon of competition. Combined with a hollow outer chainring the crankset is 20% stiffer for optimal power transfer while still saving 15 grams. Other changes include redesigned chainring teeth for better contact and power transfer. Improved bottom bracket seals further reduce contamination and friction.
- Thin-walled crank: forged aluminum crank saves weight
- Hollowchainring: saves weight while maintaining strength
- New teeth design: for better chain contact and high efficiency power transfer

Ultegra 6600 Bottom Bracket sold separately
The Hollowtech II crank and bottom bracket combine race-proven hollow forging technology with the integrated crankset & bottom bracket. Weight is reduced while rigidity and power transfer are radically increased. The crank arms are hollow which provide amazing strength and rigidity at a light weight. The SG-X chainrings enable super smooth front shifting. Special tooth profiles, pick-up spikes and ramps help make the front derailleur shift quietly, easily and trouble free.
Lengths: 165, 170, 172.5 or 175mm
Chainrings: 39 x 53
Weight: 710 g.
