FSA SL-K Light Carbon Crankset

This crankset utilizes the BB386EVO standard, which features a 30mm spindle. Because of this versatile design, it is compatible with a wide range of frame shells when paired with the correct bottom bracket adapter.

No, the FSA SL-K Light Carbon Crankset is specifically engineered for 10-speed and 11-speed drivetrain configurations. It will not provide optimal shifting performance with 12-speed systems.

The asymmetric four-bolt pattern is designed to optimize stiffness and power transfer by placing material exactly where it is needed most during the pedal stroke. It also allows for a cleaner, more aerodynamic look by concealing the chainring bolts.

This crankset is designed strictly for road cycling applications and is not Boost compatible. It is intended for standard road frame spacing and geometry.

The hollow carbon fiber arms significantly reduce rotational weight compared to solid aluminum cranks while maintaining high structural rigidity. This results in more efficient power transfer and a more responsive feel when you are climbing or sprinting.

Yes, the CNC-machined AL7075 chainrings are replaceable. You will need to ensure any replacement rings match the 110mm bolt circle diameter and the specific asymmetric four-bolt mounting pattern required by this crankset.
