ShiftMounts are adapter mounts which allows you to integrate SRAM and Shimano shifters with several different brakes from Shimano, SRAM, and Magura. Handlebar space is prime real-estate and this ShiftMount integrates seamlessly for a clean look.
Mount Type
ShiftMount naming convention is [shifter type - brake type]
MM-ISII is for a SRAM Matchmaker shifter mounting to a Shimano I-Spec II brake

MM-ISEV is for a SRAM Matchmaker shifter mounting to a Shimano I-Spec EV brake

ISEV-ISB is for a Shimano I-Spec EV shifter mounting to a Shimano I-Spec B brake

ISEV-ISII is for a Shimano I-Spec EV shifter mounting to a Shimano I-Spec II brake

MM-MAG is for a SRAM Matchmaker shifter mounting to a Magura brake

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 not compatible with Deore brakes or M6100 brakes

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.
