Race Face Sixc Cinch

The Sixc Cinch uses a 30mm spindle, so you will need a bottom bracket specifically designed for 30mm spindles, such as a Race Face Cinch BB or another compatible standard like BSA 30 or PressFit 30.

Yes, the Sixc Cinch is fully compatible with Boost spacing. You simply need to ensure you are using the correct Cinch direct-mount chainring with the appropriate offset to achieve the correct chainline.

This crankset is built for aggressive riding, specifically All Mountain, Enduro, and Downhill. Its carbon construction is engineered to withstand the high-impact forces of these disciplines while keeping weight low for efficient climbing.

The Cinch interface uses a splined direct-mount system that allows you to remove and install chainrings using a standard bottom bracket tool. This makes swapping ring sizes for different terrain or drivetrain setups much faster than traditional bolt-on rings.

The hollow carbon arm construction is designed to be exceptionally stiff, often exceeding the stiffness-to-weight ratio of comparable aluminum cranks. The 30mm aluminum spindle further ensures efficient power transfer to the drivetrain.
