The XR-One® Ultra Light TPU Inner Tube is engineered for cyclists who demand maximum performance with minimum weight. At just 36 grams, this next-generation tube delivers exceptional puncture protection, improved rolling efficiency, and dramatically reduced rotational mass compared to standard butyl tubes.

Constructed from high-resilience TPU (Thermoplastic Polyurethane), it offers a compact pack size, making it the ideal choice for road and gravel riders who want a reliable spare tube that fits easily into any pocket or saddle bag.

With compatibility for both disc and rim brakes, this tube fits 700C wheels and tire widths 18–32 mm. Available with 65 mm,  valve length, it is perfectly suited for modern aero rims (recommended for rims 38–50 mm).

Whether you're chasing lower weight, faster acceleration, or a cleaner backup solution for tubeless setups, the XR-One® TPU Inner Tube delivers elite performance for every ride.

65 mm, for rims with a height between 38 and 50 mm

• Valve type: Fina (Presta) SV, ideal for optimal compatibility.
• Application: Suitable for 700/18C-32C tires for road use.

CRUCIAL WARNING: Ensure the inner tube is properly installed before inflation. Premature inflation can cause irreversible damage.
Inflate moderately until the tube takes on a slightly rounded shape.
Specific precautions:
CO2 cartridges are prohibited due to pressure and temperature fluctuations.
The use of compressors is not recommended to preserve the integrity of the inner tube.
Reduce the pressure by 1 kg compared to a standard butyl inner tube when inflating to minimize risks associated with temperature variations.
