Product Information
The X-Grip Heavy Duty Tube for 21" Tires is designed to meet the demands of aggressive off-road and enduro riding. Made from durable 4.0 mm thick butyl rubber, this heavy-duty tube offers a strong defense against pinch flats, punctures, and pressure loss. It provides a reliable cushion between the tire and rim, helping absorb sharp impacts and maintaining consistent tire pressure through rough terrain.
Ideal for dirt bikes with 21" front wheels, the tube is a dependable upgrade over OEM or lightweight alternatives. The butyl construction also delivers excellent air retention, reducing the need for frequent inflation. Whether you're riding single-track, racing enduro, or exploring rocky trails, this tube offers added peace of mind where it counts.
