QITUEX Ridenow 700C x 32-47C TPU Inner Tubes 2-Pack — 65mm Metal Presta Valves, Lightweight Puncture-Resistant

QITUEX Ridenow 2-pack TPU inner tubes are lightweight, puncture-resistant bicycle tubes sized 700C x 32–47C with durable metal Presta valves and a detachable brass core, supplied with a repair patch kit for on-road fixes.

These tubes use modern thermoplastic polyurethane (TPU) to deliver a low-weight, long-lasting replacement for standard butyl tubes. Designed for gravel and road bikes in the 32–47mm width range, the set includes two tubes with 65mm aluminum-alloy Presta valves whose cores can be removed for easy pumping or tubeless-style adapters. The package also contains a small patch kit so you can repair minor punctures without extra tools.

How does TPU help performance compared with traditional butyl tubes?

TPU offers an improved strength-to-weight ratio, meaning these tubes are lighter while resisting abrasions and temperature extremes better than many rubber alternatives. Riders notice reduced rotational mass and a more supple ride feel, while still keeping acceptable durability for everyday use and racing.

• Weighs roughly 45 g per tube for lower rotating weight.
• High elasticity reduces pinch flats when properly installed.
• Resistant to high and low temperatures for consistent pressure hold.

Are these tubes compatible with my wheelset and pump?

The tubes cover 700C wheels with tire widths from 32mm to 47mm, fitting most gravel, cyclocross, and wider road tires. The 65mm metal Presta valve suits deeper clincher rims; the valve core is removable so you can use CO2, high-flow pumps, or valve extenders without issue.

• Valve length: 65mm fits most deep-section rims.
• Removable brass core works with inflators and liquid sealants.
• Universal fit for 700C tires sized 32–47C.

What should I watch for when installing and inflating these tubes?

TPU tubes are stretchier than butyl when first mounted, so take care to seat the bead and center the tube before full inflation. Inflate briefly at low pressure to set the tube in the tire, inspect for pinches, then pump to your recommended riding pressure. Avoid overinflating the bare tube outside the tire to prevent permanent deformation.

• Initial fill: about 0.5 PSI to shape the tube inside the tire.
• Do not exceed 5 PSI during off-tire inflation checks.
• Ensure rim walls and tire beads are clean to prevent pinching.

What does the included patch kit cover and when should I use it?

The small repair kit is intended for temporary on-road repairs to keep you riding to a safe stop or a service point. It handles small punctures from thorns, glass, or wire, but larger tears or significant cuts will need a replacement tube. Always clean and dry the puncture area before applying a patch for best adhesion.

• Contains adhesive patches for quick roadside fixes.
• Best for small, clean punctures rather than large rips.
• Use as a temporary measure until you can replace or professionally repair the tube.

Who is this product for: Cyclists who want a performance-oriented, lightweight tube for gravel and wide-road tires — racers trimming rotating weight, commuters who value durability, and weekend riders seeking a reliable spare. These QITUEX TPU tubes suit anyone running 700C x 32–47C tires and who prefers the security of a metal Presta valve with a removable core, plus the convenience of a compact patch kit for emergency repairs.
