Why do I need a guide and a Narrow Wide Chainring?
NW rings 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 chainguide and narrow wide chainring.
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.
