Race Face Six C/Atlas CINCH Spindle Kit

No, this specific spindle is designed exclusively for wider 150mm and 157mm rear hub spacing. Using it with a Boost setup will result in incorrect chainline and potential drivetrain issues.

This kit is specifically engineered for the Race Face CINCH system, including SixC and Atlas models. It is not universally compatible with every Race Face crank, so please verify that your crankset utilizes the CINCH interface before purchasing.

This spindle features a 30mm diameter, which is the standard size for the Race Face CINCH system. Ensure your bottom bracket bearings are compatible with a 30mm spindle before installation.

Yes, this spindle is an excellent option if you are moving your CINCH crankset to a frame with 150mm or 157mm rear spacing. It allows you to retain your existing crank arms while adjusting the spindle length to match your new frame's requirements.

You will need a standard 8mm hex wrench to remove the drive-side crank arm and a specific CINCH lockring tool to remove the chainring. Once those are off, the spindle can be pressed out and replaced.
