OneUp - S3 Low Direct Mount Chain Guide

The first chain guide designed to be both Oval and Boost compatible.

Narrow wide chainrings are awesome, but they're not perfect and every once in a while you can drop a chain while riding. On a social ride this means getting dropped by your friends. But when racing an Enduro a dropped chaincan cost you the podium, which is why almost every EWS pro runs both a chainguide and narrow wide chainring.

HOW CAN I DOUBLE MY CHAINRING LIFE?

As a Narrow Wide ring wears, over time the teeth thin and loose their chainretention ability, leading to more dropped chains. The OneUp guide extends chainring life by limiting the chains side-to-side movement reducing the tooth wear and totally preventing the chain from derailing. Installing a OneUp guide means you now only have to replace your chainring when the driving faces have worn out, which typically doubles your usable chainring life.
