OneUp Chain Guide ISCG05

OneUp Components

Eliminate dropped chains forever and more than double your chainring lifewith the new OneUp Components Chain Guide

At only 35g the OneUp Chain Guide weighs less than a sip of water, and can save you money in less than a season.

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


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 NW ring life by limiting the chains side-to-side movement reducing the NW 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. Buy less stuff - Work Less Ride More.
