Ontrack Ultra Light Race Tube Road

35gram French Valve Road tube 700 x 18/28c

The Ontrack bike inner tube provides all the benefits of TPU (Thermoplastic Polyurethane) — superior puncture resistance, a low weight, and compact size

TPU is a lightweight material, making TPU inner tubes lighter than their rubber counterparts. This reduces rotational weight and contributes to a more responsive and agile riding experience.

TPU inner tubes have excellent air retention properties. They minimize air leakage and maintain consistent pressure for a longer period, reducing the frequency of reinflating the tires. This is especially beneficial for long-distance rides or in remote areas where access to air pumps may be limited.
