Panaracer Purple Lite TPU 700x32~47c Presta 85mm Tube

The Panaracer Purple Lite is a lightweight TPU inner tube developed for gravel riders who want to reduce bulk and rotating weight compared with a conventional butyl tube. Its thermoplastic polyurethane construction combines flexibility and strength while folding into a compact package, making it useful both as a primary performance tube and as an easily carried spare.

Compact and Secure. Panaracer equips Purple Lite with a dedicated valve arrangement designed to improve everyday usability. A rim nut helps keep the pump head securely positioned during inflation, while the supplied base spacer follows the rim profile to help prevent the valve from rattling against the rim while riding.

Built for Inflators. The valve tip uses metal construction to better tolerate heat generated by electric inflators. The base section remains reinforced resin, so care should be taken during installation and inflation. Always confirm tyre compatibility and follow the tyre manufacturer's recommended inflation pressure.
