The Shiftmix 4 clamp combines Shimano I-Spec EV shift lever and MAGURA brake lever on just one clamp. The result is a particularly tidy look on the cockpit. I-Spec EV is the latest shift / brake lever integration system from Shimano, which is used in many 12-speed gearshifts such as the SLX, Deore XT and XTR groupsets.
