Aeron TPU ExtraLite Protect TPU Tube is a lightweight, compact inner tube designed to reduce rotational weight while maintaining the durability riders expect for everyday road and gravel use.
Built around a low-mass
TPU (thermoplastic polyurethane) construction, it packs smaller than traditional butyl tubes and is engineered to deliver low rolling resistance for a more efficient ride feel—especially noticeable during accelerations and long climbs.
- Wide-fit compatibility - sized for 650b/700c x 32–52mm tires, covering many modern road endurance, gravel, and mixed-surface setups
- 65mm Presta valve (PV) - longer valve length suits deeper rims and makes inflation easier without short extenders
- TPU construction - balances very low weight with puncture resistance for a performance-focused alternative to standard butyl
- Low rolling resistance - helps improve efficiency and maintain speed with less energy loss compared to typical tubes
- Packable spare - compact size fits easily in a saddle bag or pocket as a high-performance backup
- Up to 80% lighter than comparable butyl tubes - reduces rotating mass for a faster-feeling wheel and quicker response
