Panaracer Purple Light Ultra Light TPU Tube 700 x Presta Style 65mm Valve 23~32C TW723-32F65-PL

[Ultra lightweight] At 36 grams per tube, it is much lighter than conventional butyl tubes. It also contributes to reducing rolling resistance. [Metal and resin hybrid valve] Approximately 20mm from the base of the valve is made of resin that is lightweight and causes less damage to the rim. Approximately 45mm of the tip is made of metal and is threaded to allow attachment of a rim nut. A spacer and O-ring are included to fit the curved surface of the rim to properly secure the valve. This product is a urethane resin tube developed for bicycle racing. The handling method is very different from that of butyl rubber or latex rubber tubes, so please read the included instruction manual carefully before using it to ensure proper handling. If air leakage is due to initial failure, please contact Panaracer customer service. After inspecting the item, if it is found to be defective, we will replace it. Brand: Panaracer
