FSA SL-K Modular Crankset – Unleash Your Ride’s Potential
Built for gravel explorers and road enthusiasts alike, this modular crankset adapts seamlessly to diverse frame standards via its 30mm BB386EVO spindle, eliminating compatibility guesswork. Ideal for cyclists tackling mixed terrain—from urban commutes to rugged gravel routes—the design prioritizes lightweight performance (670g) without sacrificing durability.
Key Innovations:
– Aerodynamic Hollow Carbon Arms: UD-finish carbon construction reduces rotational mass while maintaining rigidity for power transfer on climbs or sprints
– Forged AL7050 Spindle: Precision-machined aluminum spindle ensures vibration-dampening stability across rough surfaces
– Dual-Chainring Flexibility: Direct-mount outer chainring pairs with adaptable 90 BCD inner ring for customizable gearing ratios
– Universal Drivetrain Compatibility: Works flawlessly with Shimano/SRAM 10-11spd systems (cassette not included)
Optimized For:
✔️ Gravel bikes with 135/142mm rear spacing
✔️ Road frames using standard 130mm chainline
✔️ Adventure cyclists needing +/-20mm chainline adjustment
