This system is only compatible with OneUp Switch chainring

OneUp Switch is made to make changing chainrings a quicker and easier task.

A 4mm Allen key is used to turn the bolt two turns, the chainring is rotated 20 degrees and can then be removed without first removing the crankset. The new chainring is installed by doing this in reverse order.

It is compatible with Shimano direct mount XTR M9100, XT M8100, and SLX M7100.

The bolts are tightened to 8Nm when mounting the chainring.
