  • Product Description

    At only 65g each (approx 50% lighter than a regular tube), Panaracer’s R-Air ultralight innertubes weigh less than many latex inner tubes.

    The R-Air 700c tubes are produced with a special Butyl compound, so unlike latex or other manufacturers lightweight tubes R-Air tubes do not loose air and do not sacrifice puncture resistance.

    Key Features:

    • 3 valve lengths for suitability with various top end wheel sets for the weight conscious roadie.
    • Size: 700c x18-23c
    • Valve lengths (32mm, 48mm, 60mm)
