Protect your chainring from drops with the OneUp Components Bash Guide. This guide was designed with input from top EWS racers and is made with reinforced Nylon bash guards and an 8mm 7075-T6 aluminum back plate. At just 105g (34T), it's strong enough to handle big hits but lightweight enough to go unnoticed. The OneUp Bash Guide is suitable for both enduro and trail bikes and can reduce drag for DH and bike park riders by eliminating the lower roller. With one tool installation and adjustment and tool-less flipping, it's easy to use. It comes in three sizes for compatibility with 28-36T chainrings. Not compatible with current Trek Alloy Slash & Fuel EX (gen 6) carbon frame, or Ibis Ripmo & Ripmo AF frames.
