OFFBONDAGE 2pcs Bike TPU Inner Tube 700c Gravel Road Ultralight 45/65mm Valve

OFFBONDAGE 2pcs Bike TPU Inner Tube 700c Features and Specifications

These tubes are manufactured from thermoplastic polyurethane, a trusted material that is significantly lighter than conventional butyl rubber and resists pinch flats under hard cornering loads. Each pack includes two tubes, both compatible with 700×32-47C tyre widths, so you carry a reliable spare on every ride without adding noticeable weight to your kit. The precision French valve is offered in a 45mm stem for standard-depth rims and a 65mm stem for deeper aero profiles, giving you direct compatibility with a wide range of road and gravel wheelsets. Ultralight TPU material maintains consistent air retention over multi-day tours, reducing the frequency of pressure top-ups compared to standard butyl alternatives. The valve core is removable, which allows you to use a valve core tool for fine pressure adjustments and simplifies sealant injection if you run a hybrid tubeless setup on your gravel and road ready build.
