R28 Supersonic 700×20-25C Inner Tube 42mm Valve Bundle

Continental R28 Supersonic 700×20-25C Presta 42mm Valve Inner Tube Bundle

The Continental R28 Supersonic inner tube is a super lightweight inner tube 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 weight of the inner tube can make a remarkable difference. Continental is a tried and tested brand when it comes to tyres and the trend definitely extends to their ever reliable inner tubes.
