Eliminate dropped chains forever and more than double your chainring lifewith the new OneUp Components High Direct Mount (HDM).
At only 38g the OneUp HDM 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 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.
