FSA SL-K Road Chainring

This chainring is specifically designed for 110mm Asymmetric Bolt Spacing (ABS) configurations. It is intended for use with FSA's hidden bolt cranksets, so it will not fit standard symmetric 110mm BCD cranks.

No, this chainring is optimized for 10 and 11-speed road drivetrains. It is not compatible with 12-speed systems, which typically require different tooth profiles and spacing.

Using 7075-T6 alloy provides an excellent strength-to-weight ratio, ensuring the chainring remains rigid under pedaling load while keeping the overall weight low. The CNC machining process allows for precise tolerances, which directly improves shifting accuracy.

You will need a standard set of hex keys to remove your crankset and chainring bolts. Because this is an ABS system, ensure you have the correct torque wrench settings for your specific crankset to avoid damaging the alloy threads.

The ramps and stainless steel pins are strategically placed to help lift the chain from the inner ring to the outer ring during a shift. This design ensures smooth, reliable gear transitions even when you are shifting under heavy pedaling pressure.
