Built to fit 21-inch tires with a TR-4 center metal valve, this tube offers increased durability compared with standard inner tubes. Its heavy-duty construction helps provide reliable support for trail riding, motocross, enduro, utility, and other applications where puncture resistance and impact absorption are important.
Manufactured by IRC using durable natural rubber, the T20076 inner tube is approximately two to three times thicker than a standard tube.
