Continental Race 28 Supersonic Inner Tube 700x20/25 60mm Presta 50g

The Continental Race 28 Supersonic is the inner tube you reach for when every gram counts. At just 50g, the ultra-thin butyl walls shave weight without sacrificing the reliability you need mid-race or on a fast training ride. Less rotational mass, lower rolling resistance — it's a straightforward upgrade for any performance road build.

The 60mm Presta valve handles deep-section rims with ease, and the profiled stabilising nut protects the valve during inflation while fitting both 6mm and 8mm rim holes. Fits standard 700c road tyres in the 20–25c range.
