Stan was convinced there was a better way to shift and found that reaching for the downtube to shift gears was awkward and inefficient. "Why couldn't you put the shifter on the handlebar?" he asked. "You rotate a grip, and the gear changes."While on a ski trip in Colorado, Stan made his handlebar twist shifting presentation to a friend, and brilliant engineer, Sam Patterson. Sam went back to his garage in San Diego, tinkered around for a few months, and came up with a prototype for a twist shifter by late spring. Grip Shift was born.Sram Braze-On Adaptor Wide Spacing (47.5 Chainline ) With Chain Spotter StopSRAM front derailleur braze-on clamp adapter is designed to work with the SRAM front derailleur and includes a flush side to correctly hold the derailleur as well as a lip that provides a backing for the chain catcher screw, with chains potter stop.
