What Our Gearhead® Experts Are Saying:"This tube is insanely light and compact—perfect for my minimalist bikepacking setup. The material feels high-end, and I’ve had zero air loss even on multi-day rides. Plus, the conical valve base fits super snug in the rim, so there's no annoying valve rattle. I keep a spare in every pack."Whether we're racing the clock or packing light for a multi-day ride, the Continental TPU Tube checks all the boxes for serious performance and space efficiency. Continental’s precision-built TPU design uses seven ultrathin layers of thermoplastic to maintain airtightness and resist abrasion while keeping weight to a minimum. Engineered for 29-inch wheels and disc brake setups, this tube is a go-to for modern XC, trail, and endurance riders who demand dependable performance with zero extra bulk. Its smooth, slightly conical valve base offers a tight, wiggle-free seal, while the removable core makes topping off or valve extension a breeze. Plus, it includes a repair kit, so we can patch and keep rolling.
