Latex-like performance with butyl-like durability. The R'Air is Panaracer's flagship racing inner tube, engineered to provide the supple ride quality and high elasticity of latex while retaining the air retention and easy maintenance of butyl rubber. It is a favorite for weight-conscious road cyclists and racers seeking a significant performance upgrade.

Key Features:

• High-Elasticity Compound: Features a specialized proprietary butyl compound that is 47% more elastic than standard tubes, allowing it to better absorb road vibrations and conform to the tire for reduced rolling resistance.

• Ultra-Lightweight Performance: Significantly reduces rotational weight (approx. 77g–78g) compared to standard butyl tubes, providing faster acceleration without the fragility associated with pure latex.

• Flexible Valve Options: * 48mm Valve: Ideal for standard and semi-aero alloy rims.

  • 60mm Valve: Extended length designed for deep-section aerodynamic rims, eliminating the need for valve extenders.

• Easy Maintenance: Unlike latex tubes, the R'Air can be easily repaired using a standard butyl patch kit, offering a professional-grade ride with everyday practicality.
