The Next Evolution in Lightweight TPU Tubes. With the Purple Lite, Panaracer presents a state-of-the-art inner tube that offers cyclists unparalleled performance and comfort. Thanks to the use of ultra-light materials, the TPU tube achieves an impressively low weight of just 36 grams for the road bike model (23C to 32C) and 45 grams for the gravel model (32C to 47C). Both versions can also be folded up extremely compactly, making them easy to transport and an ideal companion in the event of a puncture. The innovative improvements include a rim nut and base spacers, which not only ensure a secure fit of the pump head, but also prevent the two-piece valve from rattling. The final feature is the heat-resistant metal valve tip, which protects against the high temperatures generated by electric air pumps or inflators, and in this way, increases safety and durability.
