TPU(Thermoplastic polyurethane): the newest technological advance in bicycle inner tubes – as the fastest rolling, the most durable, and the lightest weight. It also appears to be more sustainable as it requires less raw material and is readily recyclable.

High-Strength: It offers durability and wear resistance, extending its lifespan for different road conditions.

Fastest Speed: With superior rolling resistance compared to butyl and latex inner tubes, it entices a faster and more exhilarating ride.

Safe and not easy to burst: The special new TPU material has excellent resistance to puncture.Seamless construction, with a mold-cured vulcanization, to ensure uniform roundness and give a smooth ride and handling.

Good airtightness : The bike inner tube is equipped with a high airtightness 45mm/65mm/85mm French /Schrader nozzle, which will not leak and can be used for half a year with one inflation.

This inner tube cannot be inflated a lot when it is not installed in the outer tire, otherwise it will cause irreversible damage!

Please use a manual air pump instead of high-speed air filling equipment such as air compressors or pumps.

Before inflating the RideNow tube, turn the valve inward (towards the center of the tire circle). Inflate a small amount until the inner tube is round; this pressure should be less than 0.5 bar/8 PSI.

If the vacant inflation exceeds 6PSI, the inner tube will expand beyond repair!
