Continental R28 Supersonic 700x20-25C 60mm Valve Inner Tube Bundle
The Continental R28 Supersonic is a super lightweight inner tube weighing a paltry 62 grams (claimed) to match the Supersonic tyre range. One of the most overlooked areas for weight conservation is the inner tube. Rolling weight can be almost tripled at speed and thus cutting down on something as simple and as cheap as the inner tube's weight can make a remarkable difference.
The high-quality butyl rubber construction of these inner tubes is realised via a seamless, mould-cured, vulcanised construction that guarantees consistency, reliability, air retention and low rolling resistance. They are designed to be compatible with 700c sized tyres with a width of 20mm to 25mm while the 60mm Presta valve is suited to shallow and mid-depth, aerodynamic rims.
This bundle includes five inner tubes.
