Eliminate dropped chains forever with the new OneUp Components Guide. As the trend for lower and slacker bikes continues, 'Little bikes' are getting more and more capable everyday. Revised for 2019 the OneUp Guide uses simple, one tool installation and adjustment as well as an all new tool less flip At only 40g the OneUp Chain Guide weighs less than a sip of water. 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.
