QITUEX 2 Pack Ridenow TPU Inner Tube 700C x 32-47C Gravel 45mm Valve | Brass Core & Patch Kit

Meet the QITUEX Ridenow TPU inner tubes, designed for gravel rides and everyday cycling. At roughly 45 grams each, they offer a lean silhouette without compromising durability, helping you maintain speed and control across mixed surfaces. The TPU elastomer behaves like a cushion, smoothing micro-rough patches so your tires feel more responsive on rough pavement and dirt roads alike. While lightweight, the tubes are built to resist puncture tendencies and to perform steadily under varied weather conditions.

A metal valve built from high-strength aluminum adds a secure seal while keeping weight down. The valve core is detachable, enabling simple maintenance and compatibility with threaded extensions if needed. Two valve lengths are offered, 45 mm and 65 mm, so you can tailor the tube to your rim's profile and ensure the valve stands upright with your tire bead. This flexibility makes the tubes practical for riders who switch wheels or ride across different setups.

The TPU material contributes anti puncture properties and broad temperature tolerance, supporting reliable performance across hot sun and chilly mornings. The tubes are designed for universal wheel compatibility, which helps riders mix and match rims without worrying about fit. The package also includes a repair patch kit, enabling quick field fixes if a minor puncture occurs. The combination of lightweight design, durable construction, and thoughtful details makes these tubes a versatile option for gravel routes, commutes, and training miles.

Inflation guidance and care: avoid inflating before seating the tire, and perform the first test at a conservative level, not exceeding 5 psi. After seating, inflate to your normal riding pressure following tire width and rider weight guidelines. With proper care, these inner tubes can be a practical part of a maintenance routine rather than a frequent replacement.
