Whats more frustrating than a dropped chain? Maybe smashing your chain ring on a jagged rock? The OneUp ISCG05 Bash Chain Guide will let you say goodbye to both. Installation is easy thanks to the tool-less flipping guide. It is both Boost compatible and oval chainring compatible. The Bash Guide includes three bash plates for different chainring sizes so it can be configured for whatever set up you desire. Developed by EWS racers including the Yeti factory enduro team, the reinforced nylon bash plate and 8mm aluminum back plate is proven to handle whatever impacts you might encounter. The extra protection can even be used on downhill bikes, where riders will appreciate the large reduction of drag from removing the lower pulley.
