How to Choose the Right Bike Inner Tube
Your tyre size is printed on the sidewall of your tyre. It will normally appear as two numbers, such as 700 x 28, 26 x 1.95, or 20 x 2.125. Match those numbers to the tube size to ensure a safe fit. The valve type also matters: Presta is common on road bikes, while Schrader is the car-style valve used on most kids and mountain bikes.
Presta vs Schrader
Presta valves are narrow and usually found on higher pressure road tyres. Schrader valves are wider and used on bikes with wider tyres. If your rim has a small hole, it will only accept Presta. If your rim has a larger hole, it will usually accept either.
When to Choose Thorn Resistant Tubes
Thorn resistant tubes are thicker and designed for riders who frequently deal with punctures. They add durability and are ideal for commuting, e-bikes and off-road riding.

Frequently Asked Questions
How do I know which tube size I need?
Check the writing on the side of your tyre. Match those numbers to the tube size range shown on each product.
What is the difference between Presta and Schrader valves?
Presta valves are narrow and common on road bikes. Schrader valves are the same as car valves and used on most kids and mountain bikes.
Can I use a different size tube than the tyre?
Tubes have a size range. As long as your tyre size falls within that range, the tube will fit.
Do thorn resistant tubes stop all punctures?
No, but they significantly reduce flats from thorns and debris.
Are your tubes suitable for all brands of tyres?
Yes. All tubes are universal as long as the size and valve type match.
