OneUp Components Low Direct Mount S3 E-Type Chain Guide

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 chain can cost you the podium, which is why almost every EWS pro runs both a chain guide and narrow wide chainring.

As a Narrow Wide ring wears, over time the teeth thin and loose their chain retention 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.
