A practical choice for 27.5-inch bike owners who want a reliable everyday replacement or spare tube for 2.1–2.4-inch tyres.
The Pirelli SporTUBE is a classic cycling inner tube built around reliable butyl air retention. This version fits 27.5-inch tyres from 2.1 to 2.4 inches, making it suitable for a broad range of mountain bikes and everyday bikes using this wheel size.
The 48mm Presta valve suits rims drilled for Presta valves and provides practical pump access on standard 27.5-inch wheelsets. At 200g, it is a sensible choice when you want a dependable replacement or a spare without moving to a more specialised lightweight tube.
We recommend checking the size printed on your tyre before ordering, then matching it with this tube’s 2.1–2.4-inch range. It is compatible with bikes using disc or rim brakes, so it works across a wide selection of 27.5-inch setups.
