MM-ISII is for a SRAM MatchMaker shifter mounting to a Shimano I-SPEC II brake
MM-ISII is compatible with M9020, M9000, M8000, M7000, and M6000 brake levers
MM-ISII is compatible with, but not designed for SRAM AXS because 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
