Factor’s thorn resistant bicycle tubes in 27 x 1¼ are built to keep you riding longer with fewer stops for punctures. This two-pack gives you reliable tubes that hold their pressure well and help protect your tyres from thorns, grit and everyday road debris.
If you ride older 27-inch wheels and want fewer hassles on weekend paths, commutes or rail trails, these tubes make life easier. They’re thicker where it counts, so the tube is better at shrugging off the sort of small punctures that usually leave you stranded at the worst moment.
Who is this for?
Ideal for riders who want a simple way to cut down on punctures, especially anyone on a classic 27-inch road bike or commuter that still sees regular use. Great for riders who prefer Schrader valves and want a pair of tubes ready to go, whether for immediate replacement or to keep as spares.
Who is this not for?
Not the best choice if you’re chasing the lightest possible setup or riding high-performance modern 700c wheels. If your priority is shaving grams for racing or fast group rides, a standard lightweight tube may suit you better.
Why we love it
We’ve found these hold up well on typical Australian paths and back streets where thorns and fine wire can ruin a ride. Our favourite part is how much peace of mind they give, especially for riders who just want their bike to work every time they head out.
Hot tip!
When fitting thorn resistant tubes, check inside the tyre for any embedded debris before installing. A quick wipe with a clean cloth or your glove often stops the next puncture before it happens.

Sturdy. Riding in bicycle lanes littered with metal debris and broken glass. Haven’t had a puncture in these new tubes yet. Didn’t anticipate the slightly harsher ride, but worth it.
Haven’t put them on yet, but they are what I ordered.
