FSA SL-K Crankset

While it is optimized for gravel and adventure riding, the SL-K Modular is perfectly suitable for road use. Its stiff, lightweight carbon construction performs well across varied terrain, provided your frame supports the 386 EVO bottom bracket standard.

This crankset uses a 386 EVO bottom bracket interface. Because it features a 30mm spindle, it is highly adaptable to many frame standards, but you must ensure you have the correct bottom bracket adapter or shell compatibility for your specific bike.

Yes, the modular design allows for flexibility. It utilizes a direct mount outer ring system, which makes maintenance and chainring swaps straightforward compared to traditional bolt-on configurations.

No, this specific model is designed for 11-speed drivetrains. Using it with a 12-speed system may result in poor shifting performance and premature wear.

The hollow carbon fiber arms significantly reduce rotational weight while maintaining high stiffness. This translates to more efficient power transfer with every pedal stroke, which is particularly noticeable during steep climbs or long days in the saddle.
