BUCKLOS 700C TPU bike inner tube is engineered for modern road and gravel riding, delivering reliable performance with versatile sizing and flexible Presta valve configuration. It comes in two core size specifications: 700C x 23‑32C compatible with 23C, 25C, 28C, 30C, and 32C tires, and 700C x 33‑45C fitting 33C, 35C, 38C, 40C, 42C and 45C tires. This inner tube adopts a removable‑core Presta valve and provides three valve‑length options: 45MM, 65MM and 80MM. The 45 mm fits standard‑depth rims, the 65 mm fits mid‑depth rims, and the 80 mm fits deep‑section carbon rims. For a seamless fit, measure your rim depth before purchase; select a valve roughly 20 mm longer than your rim depth for optimal installation. Built with premium‑grade 0.25 mm single‑layer TPU material, this inner tube greatly cuts rotating weight while maintaining compact footprint, excellent air retention and long‑lasting durability. The 700C 23‑32C model weighs around 35g, whereas the 700C 33‑45C weighs approximately 40g. Nearly 75% lighter and 85% more compact than standard rubber inner tubes, it features an 18% improvement in inflation efficiency and stows effortlessly in saddle bags or jersey pockets — ideal for light packing on long rides, weekend adventures and race days. Riders can replace worn valve cores as needed or swap to a click‑style valve to build personalized riding setups. Suitable for beginners trying TPU inner tubes for the first time as well as seasoned cyclists chasing speed, BUCKLOS TPU bike inner tube acts as a practical lightweight replacement for road and gravel bikes across road races, gravel outings, daily commutes and high‑intensity training sessions. Important installation guidance: Give the inner tube slight pre‑inflation before fitting to check air tightness. Never inflate beyond 5 PSI / 0.3 Bar until the tire is fully seated on the rim; exceeding this limit will cause permanent irreversible damage to the TPU inner tube.
