Convert your mountain bike rims to run tubeless tires with the tenacious seal of the MTB Tubeless Tape by Mercury Wheels. Nine meters of tape is more than plenty to wrap two rims, plus the 27-millimeter width covers most mountain bike rims in the neighborhood of 30 millimeters, give or take a few millimeters. It'll work with Mercury's X1 Enduro carbon and X3 Enduro alloy rims, as well as other manufacturer's popular trail and enduro hoops. Super-sticky adhesive provides a solid hold without damaging carbon or aluminum rims.
