Fat/Plus TPU Tube 26 x 4.0-4.5" PV 48mm

BikeTube Fat/Plus TPU Tube 26 x 4.0-4.5" PV 48mm brings modern tube technology to fat bike and plus-size tires, cutting serious weight without compromising durability. Built from advanced thermoplastic polyurethane (TPU), this tube transforms your ride with smoother rolling, stronger performance, and better air retention than traditional butyl. Riders looking to shave grams and boost efficiency on every trail will appreciate the difference the moment the tires hit dirt.

These tubes are more than 70% lighter than standard butyl, saving up to 1.8 pounds across both wheels—a game changer for heavy fat bike setups. The improved material strength also means fewer flats and less time spent on maintenance, while the included alcohol prep pads and patches make quick fixes easy when you need them.
