TPU Tube - 29in

What Our Gearhead® Experts Are Saying:

"I’ve tested a lot of lightweight tubes, but this one stands out for its airtightness and compact size. At 43 grams, it’s lighter than most CO2 cartridges and fits easily in a frame bag. I’ve used it on multiple tubeless conversions and it seats cleanly every time when needed in a pinch."

The Continental TPU Tube 29 x 1.6–2.4 is built for riders who demand every performance edge: it's lightweight, compact, and engineered with precision. This thermoplastic tube uses a proprietary seven-layer construction to ensure exceptional air retention, abrasion resistance, and durability, all while weighing just 43 grams. It's the perfect solution for backup use, race-day setups, or minimalist packs where space is at a premium.

The smooth, conical valve base reduces movement and creates a stable seal against the rim, while the internally threaded valve core accepts extenders or replacements. Its ultralight design is best suited for disc brake applications, and Continental even includes a repair kit, so you're never caught off guard. Designed for modern 29-inch wheels, this TPU tube is everything you want in a high-performance spare.
