Compatibility

Designed to work with rear (right side) brakes and shifters.
Consult the brake and shifter manufacturers to understand which mounting interface you have on your brakes and shifters.
MM-ISEV is compatible with M9100, M9120, M8100, and M7100 Brakes. Deore M6100 or M4100 brakes will mount but the positioning not optimal so we would consider them not compatible.
MM-ISEV, MM-ISII, & MM-MAG is compatible with but not designed for SRAM AXS. With SRAM AXS, the shift lever will be further towards the end of the bar, or closer to the rider's hand than is ideal for most riders.
Shimano I-SPEC A, Hope, and TRP brakes are not supported.
Shimano I-SPEC EV to Magura brakes is not supported because of geometric challenges.
ISII- 22 Clamp is compatible with Shimano XT M8000 and XTR M9000 shifters.
NOT compatible with Shimano SLX M7000, Deore M6000.
For handlebar clamp ShiftMounts tighten clamp bolt to 1-2 Nm max torque.
