The new Shiftmix 4 handlebar clamp combines a Shimano I-Spec EV shifter and a MAGURA brake master in a single  clamp. The result is a clean, uncluttered look. The I-Spec EV, Shimano's latest integrated shift/brake system, is used in many 12-speed shifters in the newest Deore, XT and XTR shift groups.

*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.
