Race Face Aeffect Cinch Crank Arms

These crank arms use a 24mm spindle and are designed specifically for 24mm EXI bottom brackets. If your current frame setup uses a standard 24mm interface, they will be a direct fit.

The Cinch system is a modular direct-mount interface that lets you swap chainrings quickly without removing the entire crankset. It makes changing your gearing for different terrain or converting between single and double chainring setups much easier.

Yes, they are built from forged and CNC-machined 6066 aluminum, which is specifically engineered to handle the impacts and stresses of aggressive trail riding while remaining light enough for cross-country use.

You need to use chainrings that are compatible with the Race Face Cinch direct-mount standard. While this limits you to Cinch-specific rings, it offers a wide variety of tooth counts and oval or round options within that ecosystem.

The Race Face Aeffect Cinch crank arms weigh approximately 650g. This weight profile strikes a solid balance between the durability needed for trail riding and the efficiency required for XC racing.
