What Our Gearhead(R) Experts Are Saying:"This TPU tube is my secret weapon for race day and long gravel rides. It's incredibly compact and weighs less than a snack bar. I keep one in my saddle roll for emergencies, and the valve design makes it easy to use with extenders when I'm running deep wheels."When space and weight matter, we turn to the Continental TPU Tube. It's crafted with micrometer-thin thermoplastic polyurethane layered seven times to provide airtightness and puncture resistance without adding bulk. At just 35 grams, it disappears in our jersey pocket or saddle bag, yet delivers performance we can count on when flats strike mid-ride. Ideal for performance-focused road cyclists and gravel grinders alike, this disc-specific tube is precision-engineered for smooth installation and reliable pressure retention. The uncolored TPU eliminates issues caused by dyes or coatings, while the slightly conical valve base keeps it snug in the rim with less wobble. With a removable valve core and a repair kit included, it's ready for the long haul and the unexpected.
