Shimano I-spec II collar for XT shifter

This is a simple collar for a Shimano XT M8000 shifter with I-spec II plug.
I made it when I buid a custom bike and wanted to mix SRAM brakes et Shimano I-Spec II shifter.

If you look for a piece to directly mount I-Spec II shifters on SRAM brakes, have a look at :
