PERTUAL RideNow TPU road bike inner tubes 700/18C-32C 36g 4Pack, Metal 65mm Presta valve, ultra-light puncture-resistant

PERTUAL RideNow TPU inner tubes are ultra-light, puncture-resistant road bike tubes sized 700 x 18C–32C with metal/TPU Presta valves for reliable inflation and lower rolling weight.

These RideNow tubes swap traditional butyl rubber for thermoplastic polyurethane (TPU) to cut weight and improve durability while keeping compatibility with common 700c road tires. Sold as a four-pack, they include valve length options (65mm or 85mm metal/TPU Presta) and a small repair patch kit so you can ride with minimal downtime. The design focuses on airtightness, puncture resistance, and ease of installation for everyday training, commuting, or weekend group rides.

How much lighter are these TPU tubes compared with standard butyl tubes?

TPU construction makes a substantial reduction in mass versus older butyl designs, improving packability and responsiveness. Lighter tubes reduce the rotating weight of your wheels, which riders notice during accelerations and climbs.

• Approximately 70% lighter than comparable butyl inner tubes.
• Sold in a 4-pack to outfit multiple bikes or serve as spares.
• Smaller packed size for easier storage in saddle bags or jersey pockets.

Will these tubes resist punctures and hold air reliably?

TPU offers higher abrasion and puncture resistance than many standard polymers, while the optimized Presta valve assembly improves air retention. The tube material resists oil and water and maintains stable performance even at lower pressures.

• TPU material engineered for wear resistance and anti-aging properties.
• Enhanced valve core and valve pad rubber reduce leakage and friction.
• Includes a small patch kit for roadside or garage repairs.

Which tire sizes and valve lengths do these inner tubes fit?

RideNow tubes cover a common range of road tire widths, making them suitable for most modern 700c setups. Choose the valve length that matches your rim depth or spoke hole position for easy pump access.

• Compatible tire widths: 700 x 18C–28C and 700 x 18C–32C.
• Valve options: metal or TPU Presta valves in 65mm or 85mm lengths.
• Includes tubes sized correctly for road and gravel-adjacent tire profiles.

How should I install and inflate these TPU inner tubes to avoid damage?

TPU behaves differently from butyl during installation; initial careful inflation prevents pinching and deformation. Follow the recommended inflation steps to seat the tube inside the tire before final pressure adjustments.

• Avoid overinflating the tube outside the tire to prevent irreversible stretching.
• Begin installation with a 0.5 PSI partial inflation so the tube fits the tire wall.
• Once seated, gradually inflate to your target pressure while checking bead seating.

Who this is for: PERTUAL RideNow 4-Pack TPU inner tubes suit cyclists who prioritize lower rotating weight, spare-tube convenience, and improved puncture resistance compared with basic butyl tubes. They are a practical choice for road racers, weekend climbers, daily commuters, and cyclists who carry compact spares. Riders using deeper rims should choose the longer valve option, and anyone new to TPU tubes should follow the installation guidance to avoid pinch damage. The included patch kit and multiple valve lengths make this set a straightforward upgrade for most 700c road tire setups.
