ExtraLite Protect TPU Tube, 700 x 23-28mm, 42mm PV

Aeron TPU ExtraLite Protect TPU Tube is a lightweight road bike inner tube built to reduce rotating mass while staying practical for everyday riding and fast spares. The TPU construction packs down smaller than traditional butyl tubes and is designed for low rolling resistance and puncture resistance—ideal for riders who want a faster-feeling setup without switching away from standard clincher tires.

Sized for 700c x 23–28mm tires and fitted with a 42mm Presta valve, it’s a clean match for many modern road rims and a smart upgrade for training and racing alike.
