The MAGURA Shiftmix is an adaptor clamp designed to let you use any MAGURA MT, CT, or HS series brakes with SRAM trigger shifters all using just the one Shiftmix clamp (just like the Matchmaker SRAM uses). It is a great way to shave a few grams off your bike and still offer secure brake and shifter retention on your handle bar. *This mounts the shifter to the Right hand side of the brake clamp. Depending on your brake master/lever placement, this might push the shifter too far towards the grip
