The Freedom Thorn Resistant Bike Tubes are a great choice for cyclists who want fewer punctures and more time enjoying their cycling. Designed to suit 27.5 inch (650B) tyres from 1.90 to 2.40 inches wide, these heavy duty bike tubes provide extra peace of mind for commuting, recreational cycling, fitness and trail use.

If you’re tired of stopping to repair flats, these thorn resistant inner tubes are well worth considering. Their thicker construction helps resist punctures caused by thorns, sharp debris and small road hazards, making them ideal for bike riders who regularly cycle on shared paths, roads, parks or light gravel tracks.

Extra puncture protection

The standout feature of these Freedom tubes is their thorn resistant construction. Compared with standard inner tubes, the thicker rubber helps reduce the chance of punctures from common hazards, allowing you to spend more time cycling and less time fixing flats.

Perfect for 27.5 inch (650B) bikes

These tubes are designed to fit 27.5 inch (650B) tyres with widths from 1.90 to 2.40 inches. They’re suitable for many mountain bikes, hybrid bikes and recreational bikes, making them a versatile replacement or spare to keep on hand.

Schrader valve for easy inflation

Each tube features a 48mm Schrader valve, the same style commonly found on car tyres. This makes inflation straightforward with most floor pumps, service station air compressors and many portable bike pumps.

Handy set of two

With two tubes included, you’ll always have a spare ready when you need it. It’s a practical option for cyclists who like to carry a backup on longer rides or keep an extra tube in the garage for quick repairs.
