VNoïse ATOM TPU bicycle inner tube, 700x18-32

Designed to optimise wheel weight and the bike’s dynamic performance, the ATOM 700x18-32 TPU inner tube from VNoïse stands out for its compact and ultra-lightweight design. Made from high-performance TPU, it offers a modern, lightweight alternative to traditional butyl inner tubes. Thanks to UHD thermoforming, it offers precise and consistent manufacturing, ensuring a technically advanced, thin and uniform inner tube. Its very low weight (between 32 and 35 grams depending on valve length) significantly reduces rotating mass, resulting in better responsiveness and increased dynamism during accelerations and changes of pace.

Ideal for road cycling and triathlon, it is designed for cyclists looking to lighten their bike setup whilst maintaining good pressure retention and ease of use. Its distinctive yellow colour and the valve engraved with ‘ VNoïse TPU ATOM’ provide a neat, easily recognisable finish. Compatible with 25–32 mm tube-type tyres, it is available in several valve lengths (48, 60, 80 and 100 mm) to suit different rim heights. Compact when folded, it also takes up very little space in a saddle bag, making it an excellent choice both as your main tyre and as a spare.

Valve size depending on your rim height:

48 mm valve for rims from 15 to 35 mm.

60 mm valve for rims from 36 to 50 mm.

80 mm valve for rims from 51 to 65 mm.

100 mm valve for rims from 66 to 86 mm.

Fitting tips:

1: Check the rim flange and the inside of the tyre.
2: Inflate the inner tube slightly before fitting.
3: Avoid pinching the inner tube during installation.
4: Use only plastic tyre levers.
5: Inflate using a pump; do not use CO₂ cartridges or a compressor.
6: Adhere to the recommended pressures (= 1 bar less than a butyl inner tube, within the tyre and rim specifications).
7: Avoid exposure to excessive heat.
8: In the event of a puncture, use only a TPU repair kit.
