OM-1 Shifters - Indexed Thumb - MicroShift, 9 speed

This new RBW-branded thumbie has both a friction and index mode, and is made for us by Microshift specifically for the OM-1 rear derailer. Some customers have found that the OM-1 indexes fine with existing Shimano and Microshift shifters, but Microshift’s standards are higher still, and they monkeyed with the internal click-stops until the indexing was perfect by their higher standards. Solidly built, reasonably light, nicely finished, and comfortably familiar to other thumbies and BES.

The friction mode lacks the light magical superfaint tick-tick of the power ratchet in the Silver shifters, but is smoother than Shimano’s friction mode, and works perfectly. We still encourage you to shift in friction, but if you prefer indexing or aren’t ready to commit wholly to friction, raise your glass in a toast to these great shifters. We’re thrilled to have them.

This is meant to be mounted on the right outside. If you want to mount it on the inside, like we mount our Silver thumbies, you'll have to use it on the left. It'll work perfectly and you'll get used to it in no time. 

To switch between friction and indexing, loosen the shifter with a 4mm allen and turn the red dot to either the 9, for indexing, or the F, for friction. Once you switched it, tighten the shifter back up.
