What Size Inner Tube Do I Need?
Follow these three simple steps to find the right size inner tube for your bike.
1. Wheel Size
Inner tubes are made to fit specific wheel sizes, so you need to know what size the wheel on your bike is.
The easiest way to do this is by looking at the tyres on your bike. On the sidewall you'll see a combination of digits such as:
700 x 28c (road bike wheel) or 27.5 x 2.4 (mountain bike wheel)
It’s the first figure that shows the diameter of the wheel or the wheel size.
The next figure is tyre width which is the other measurement you need to know.
2. Tyre Width
Inner tubes are designed to fit a range of tyre widths, so the next thing you need to know is the width of your tyre.
This is shown in the second number that’s printed on the side of the tyre.
700 x 28c (road bike wheel) or 27.5 x 2.4 (mountain bike wheel)
When choosing an inner tube you need one with a width range that covers your tyre width as well as exactly matching the size of the wheel. See the tables below for examples.
Note: Sometimes metric sizes are shown as c instead of mm. This is just a different way of saying the same thing. A 25c tyre is the same width as a 25mm tyre.

3. Valve Type
There are two types of inner tube valve; Shrader and Presta. The easiest way to see which one you need is to look at the tube on your bike.
Schrader Valve
Easily identified by the 'car type' stubby profile.
These valves are often found on entry-level hybrid, mountain and kids bikes which run on lower tyre pressures.
It is worth noting that Schrader valves require a slightly larger hole in the rim. This means that you can use Presta valve tubes on a Schrader compatible wheel rim but not the other way around.
Presta Valve
These have a long and narrow profile. They have a central core you unscrew before inflating the tube.
Presta valves are often used on road bikes which run at higher tyre pressures as well as mid to high-end mountain bikes.
These valves come in a range of lengths. Longer valves are designed for use with deep section aero rims.
My tyre size looks different - ETRTO Sizing
Sometimes tyre size on the sidewall of your tyre is shown in the ETRTO format like this 54-559 or 23-622. ETRTO size tyres are the same size as Imperial / Metric tyres, it’s just that the measurements are shown differently.
All our inner tubes are listed in Metric or Imperial sizing but you can use the table below to convert your ETRTO size to Imperial for MTB tyres or Metric for road bike tyres.

The Benefits Of Self-Sealing Inner Tubes
Punctures are inevitable. Instead of having to lug around spare inner tubes with you, you can opt for a self-sealing inner tube. These bike inner tubes are delivered with tube sealant already inside. When you get a puncture the sealant will plug the gap so you can keep riding.
