What is a TPU bicycle inner tube?

A TPU inner tube is made from thermoplastic polyurethane instead of butyl rubber. TPU allows much thinner walls with higher tensile strength, so the tube is significantly lighter and packs far smaller while resisting punctures and ageing.

How much lighter is a Tubolito than a butyl tube?

A typical butyl road tube weighs around 100 g. The Tubolito S-TUBO Road weighs 23–25 g and the Tubo-Road 38–40 g, which reduces rotating mass at the wheel by up to roughly 75%.

Can Tubolito tubes be repaired?

Yes. Tubolito tubes can be repaired with the dedicated Tubolito patch kit designed for TPU. Conventional rubber patches and vulcanising glue do not bond reliably to TPU.

Are Tubolito tubes compatible with rim brakes?

Compatibility depends on the model. The ultralight S-TUBO models are intended for disc-brake bikes, while other ranges are approved for broader use. Always check the compatibility notes on the individual product page.

Can retailers, distributors and OEMs source Tubolito tubes?

Yes. Tubolito works with bike shops, distributors and OEM partners worldwide. Business customers can find programme details on the B2B page and locate existing partners through the dealer locator.
