FSA SL-K Light Crankset

The FSA SL-K Light is designed for the 386EVO bottom bracket standard. Because it features a 30mm spindle, you will need to ensure your frame's bottom bracket shell is compatible or that you have the correct adapter for your specific setup.

No, this specific model is optimized for 11-speed drivetrains. Using it with a 12-speed system may result in poor shifting performance and increased wear due to the chainring tooth profile.

The 30mm spindle is significantly stiffer and lighter than traditional 24mm spindles. This design allows for more efficient power transfer from your legs to the drivetrain, reducing flex during hard efforts or sprints.

The hollow carbon arm construction allows the crankset to be exceptionally lightweight without sacrificing structural integrity. This stiffness-to-weight ratio ensures that your pedaling energy is directed into forward motion rather than wasted on component flex.

Yes, the chainrings are replaceable. This crankset uses a 110mm Bolt Circle Diameter (BCD), so you can swap them out for different gear ratios or replace worn rings as needed.

The Q-factor refers to the distance between the crank arms where the pedals attach. A 174mm Q-factor is standard for many road and gravel bikes, but if you are sensitive to stance width, it is worth comparing this measurement to your current crankset to ensure it matches your preferred riding position.
