Eliminate dropped chains forever and more than double your chainring life with the new OneUp Components ChainguideAt only 35g the OneUp chainguide weighs less than a sip of water, and can save you money in less than a season. Narrow-wide (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, a dropped chain can cost you the podium, which is why almost every EWS pro runs both a chainguide and NW chainring.

As a NW 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. Buy less stuff - Work Less Ride More.
