FSA K-Force WE Bike Crankset 172.5mm – Lightweight Performance Upgrade

Hollow Carbon Crankset for Triathlon & Time Trial Dominance

Engineered for elite performance in high-stakes racing scenarios, this Hollow Carbon Crankset redefines efficiency for triathletes and time trial specialists seeking a lightweight yet rigid drivetrain solution. Crafted with advanced UD carbon arms and a forged AL7050 BB386EVO spindle, it combines aerodynamic sleekness with unmatched power transfer—ideal for slicing through wind resistance on open roads or endurance triathlon courses.

Key Innovations:
– Variable Thickness Design: Strategically reinforced at stress points while minimizing material elsewhere, achieving a featherlight 534g without compromising stiffness.
– Precision Chainring Engineering: AL7075 forged pins undergo full CNC 3D machining for razor-sharp upshifts and unwavering chainring stability under maximum torque.
– Universal Compatibility: Fits modern road frames with BB386EVO standards, making it a versatile upgrade for both race-day setups and training rigs.

Why Choose This Crankset?
Triathletes demand gear that excels under pressure—this system delivers. The double 50/34 chainring configuration pairs seamlessly with 11-speed drivetrains, offering crisp gear transitions whether sprinting out of T2 or maintaining tempo on long TT efforts. The black UD carbon finish not only resists corrosion but also adds a stealthy aesthetic to any race bike.

Competitor Comparison Snapshot
| Feature | This Crankset | Aluminum Competitors |
|———————–|————————|—————————-|
| Weight | 534g (hollow carbon) | 700+g (solid alloy) |
| Stiffness | Optimized variable geometry | Uniform thickness = extra bulk |
| Spindle Compatibility | BB386EVO (widely adopted) | Limited standards |
| Chainring Durability | CNC-machined AL7075 | Cast alloy (less precise) |

Designed for riders who refuse to compromise between speed and practicality, this crankset merges cutting-edge materials with real-world performance. Whether chasing personal bests in a time trial or conquering the grueling bike leg of a triathlon, every gram saved here translates to watts gained at the pedals.
