“Eliminate dropped chains forever and more than double your chainring life with the new OneUp Components Chainguide.
How can I double my chainring life?
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 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.
