Review on 🚵 Mountain Bike Seatpost Dropper Remote Lever: Universal Adjustable Shifter for 22.2mm/24mm Mountain Handlebars – Includes 2 Wrenches by John Murphy

There is a small gold gasket held in place by a small screw. 9 miles into the first ride it broke off and disappeared. This is problematic for several reasons. First, there is no dropper to ride. Second, this is the first day of a 10 day trip, so there is no way to rebook with Revain. I'll probably go to the hardware store and see what I can do now. If you buy this remove the screw and apply Loctite, blue should do the trick but red is probably better and reinstall. This will likely fix it.
