FSA SL-K Modular

The FSA SL-K Modular uses a 30mm spindle and is specifically designed for the BB386EVO bottom bracket standard. Because of its modular nature, it is compatible with a wide range of frame shells, but you should verify your frame's specific bottom bracket shell width and type before installation.

No, this specific model is optimized for 10 and 11-speed drivetrains. Using it with a 12-speed system may result in poor shifting performance and increased wear on your chain and chainrings.

The hollow carbon fiber construction significantly reduces the overall weight of the crankset compared to solid aluminum options without sacrificing stiffness. This provides a more efficient power transfer during hard efforts while keeping your bike's total weight down.

The 46/30T setup is a sub-compact configuration primarily intended for gravel and adventure riding where you need lower gearing for steep, loose climbs. While it works on the road, you may find yourself spinning out on fast descents compared to a standard 50/34T or 52/36T setup.

The modular design allows you to swap out chainrings or spiders more easily than fixed-spider cranksets. This makes it simpler to change your gearing ratios for different terrain or replace worn chainrings without needing to replace the entire crankset.
