Positz inner tubes are a simple way to keep your bike rolling without fuss. Made to fit a wide range of 700c tyres from 28mm up to 45mm, plus older 27-inch wheels, they give you reliable performance at a fair price. With Schrader valves, they’re easy to inflate at home, at the servo or with a standard pump.

Every rider knows punctures happen, so having a pair of spare tubes ready saves the hassle of getting stranded. These tubes shine on road, commuting and gravel bikes where versatility matters. With two in the box, you’ve got a back-up for today and a spare for the next ride.

Who is this for?

Ideal for riders who want a no-nonsense spare tube that just works. Great for commuters who need a dependable option, weekend road riders looking for an easy swap, and gravel cyclists who like the peace of mind of carrying an extra.

Who is this not for?

If your bike runs on skinny racing tyres under 28mm, or if you’re using presta-only rims, this isn’t the right choice. Riders chasing the lightest-weight performance tubes or tubeless setups should look elsewhere.

Why we love it

We like these because they cover so many tyre sizes in one go, making life easier when you’re grabbing spares. Plus, the Schrader valve means you’re never stuck looking for a special pump – it’s the same as a car tyre valve.

Hot tip!

Keep one tube in your saddle bag and the other in your garage or backpack. That way you’re covered on the ride, and you won’t forget to restock after your next puncture.
