I see they have a mounting option for Shimano M9100-M9120 brakes with a Sram MatchMaker shifter, but do they have a mounting option for Sram MatchMaker X brakes to a Shimano I-Spec Ev shifter? It looks like the Wolftooth one you mentioned would work for both, as the I-Spec Ev brake mount seems almost identical to Sram MatchMaker, and the I-Spec Ev shifter mount appears to just need a pinch bolt to hold it in the desired position. Has anyone tested this? Currently unable to ride until I can get the proper adaptor... Should have just bought a standard band clamp shifterYou buy a isev spec to sram matchmaker adapter and you're all set.
Wolfthooth components makes one
