FSA SL-K Crankset

ABS stands for Asymmetric Bolt Spacing. This design optimizes the crank's structural integrity by placing material exactly where it is needed most, resulting in more efficient power transfer from your legs to the drivetrain.

This crankset uses the BB386EVO standard with a 30mm spindle. While it is highly versatile and compatible with many frame standards, you will need to ensure you have the correct bottom bracket adapter or shell compatibility for your specific bike frame.

It is designed for both. The carbon fiber construction keeps the weight low for efficient climbing, while the stiff architecture ensures that your power output is maintained during high-torque efforts like sprinting.

Yes, this is a complete crankset that includes two chainrings. It is available in standard configurations of 50/34T for climbing-focused gearing or 53/39T for higher-speed performance.

FSA engineers these cranks to balance weight savings with high durability. While carbon fiber is lighter than aluminum, it is also incredibly stiff and resilient, making this crankset a reliable choice for both competitive racing and high-mileage training.
