Product Description - practical, versatile, inexpensive The is part of the Switch Direct Mount chainring system and, unlike previous Switch chainrings, is also compatible with Shimano Hyperglide+ 12-speed chains. Thanks to OneUp Switch, you can change the chainring in almost no time at all. Only a 4 mm Allen key is required to complete the set-up in the shortest possible time, and the crank does not need to be removed. So if a steep trail gets in your way, you can switch to a smaller chainring in the parking lot. The Switch chainrings are uncompromisingly optimised and have already been successfully tested in the Enduro World Series. Their narrow-wide structure prevents the chain from dropping. And you'll save money with them too, because a OneUp Components Switch replacement chainring costs less than a new Direct Mount chainring.
