Reflex v2.1 lock on grips have been in development for a couple of years which included elite rider testing on the UCI Downhill World Cup Series and the EWS as well as weekend warriors to give us feedback from a wide spectrum of riders. This culminates into a grip that offers optimal performance without sacrificing comfort as each area of the grip has been designed for a specific performance purpose. Made with our medium durometer proprietary grip compound, with its superior impact dampening properties, it is designed to reduce arm pump and fatigue whether you are racing down the worlds toughest DH or Enduro courses or spending all day riding your local trails.
