Leave it to OneUp to pack so much goodness into a chainguide. The Oneup S3/E-TYPE Chainguide (low direct mount) weighs just 20 grams, yet promises to eliminate dropped chains forever while also doubling your chainring life. How? 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.
