This PIVOTRAX inner tube is designed to fit most 3.00-19 MX tires (also listed as 70\/100-19, 2.75\/3.00-19, 80\/100-19), with a 2 mm thick butyl rubber body and a reinforced TR4 valve stem to reduce flats and valve failures. It balances durability with compatibility so you can replace tubes quickly and get back on the trail.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tube handle electric bike weight and torque?\u003c\/h3\u003e\n\u003cp\u003eThe 2 mm reinforced butyl compound increases puncture resistance and slows down heat buildup under higher loads typical of e-bikes.
