TerraCycle Bar End Shifter Micro Mount – 30mm – MicroSHIFT

Replaces the special bolt on the fixed (non lever) side of your bar end shifter and adds a nice little spot to attach smallish things like motor controls, cycle computers, and electronic shifter buttons. The outside diameter is 7/8″ (22.2mm), so all kinds of standard bike things can go there. A plastic cap is included in case you only want to attach things on the outside.
