These clamps/adapters allow you to mount your OneUp Components Dropper Remote (V2 or V3) to either Shimano or SRAM brake clamps, flat / MTB bars (22.2 Clamp), or drop bars (31.8 clamp).
The 22.2 Flat Bar Clamp and the Drop Bar Clamp are stand-alone clamps allowing the remote to mount/attach to your bars without attaching to a pre-existing clamp or brake mount.
The SRAM MMX, Shimano I-SPEC EV, and the I-SPEC II Adapters are not clamps. These adapters allow the remote body to mount to the pre-existing clamp or brake mount on the bike:
SRAM Matchmaker X – SRAM MMX clamps
Shimano - I-SPEC-EV – 12 speed XTR M9100, XT M8100 and SLX M7100
Shimano I-SPEC-II – 11 speed XTR M9000, XT M8000, SLX M7000 only
