Specialized Inner Tube

This tube features a dual-thickness design. The outer wall, which faces the tire, is thicker to block thorns and debris, while the inner wall facing the rim is thinner to keep rotational weight down.

Yes, provided your tire width is between 1.75 and 2.4 inches. It is designed specifically for 29-inch wheels with an ISO diameter of 622.

Because of the reinforced outer wall, it may feel slightly stiffer than a standard lightweight tube. However, it installs just like any other tube—just ensure you seat the bead properly and avoid pinching the tube during installation.

This tube comes with a 40mm Presta valve. If your rims have a deep profile or you are using rim tape that significantly reduces clearance, you may need a longer valve stem or an adapter.

While the reinforced construction significantly reduces punctures from thorns and small debris, no tube is entirely flat-proof. It offers a substantial upgrade in protection over standard tubes, but you should still maintain proper tire pressure to prevent pinch flats.
