Bike Tubes

As every cyclist knows, flat tyres are a common problem. Don't get caught out by not having either a spare tyre or puncture kit with you! If you are looking for a new inner tube, make sure you know what the correct diameter and width of your tyres are, as they vary from bike to bike.

With both branded and universal bike tubes at Anaconda, you will be able to find the right sized tube for your bike's wheels. If in doubt, refer to the side wall of your tyre or the product details of your bike for information on sizes.

Can I purchase bike tubes at Anaconda?

Yes, you can. If you are new to the world of cycling however, you will need to do a little bit of homework to make sure you get the correct inner tube for your particular bike. If that sounds like too much trouble, it is best to leave it to an expert, like your local cycling shop, to repair your punctures, as fitting the wrong inner tube can lead to even more problems. However, if you are keen to have a go, here are some of the things you need to keep in mind:

What is an inner tube?

An inner tube is a balloon-like structure, which can be inflated and deflated using a valve. The inner tube is like an air-cushion, and when inflated beneath the tyre, it is what provides you with a comfortable, safe ride. Unless you've converted your bike to tubeless tyres, the chances are that your bike has inner tubes. However, with so many wheel and tyre sizes out there, you need to make sure you identify the correct size for your bike.

Which inner tube do I need?

Inner tubes come in a range of sizes as well as two main valve types. These are the two key issues to consider when finding the right inner tube.

Size: Inner tubes vary in size depending on the circumference of the wheel and the width of the tyre:

1. Wheel diameter or circumference: Depending on whether your bike is a road bike, touring bike, mountain bike or child's bike, the diameter/circumference of the wheel can vary.

2. Tyre width: To add to the variety, you also have different tyre widths. There are wide road tyres and narrow road tyres; wide downhill mountain bike tyres and narrow cross-country mountain bike tyres.

To ensure that you get the correct size of inner tube for your tyre, check the sidewall of your tyre. Printed onto the tyre you should see something like "700x23c" on a road bike, or "29x1.9" on a mountain bike. The first number refers to the circumference of the wheel; the latter refers to the width of the tyre. If you cannot see the printed text on your tyre anymore through dirt or wear, you can usually find the details on the paperwork that came with your bike at the time of purchase.

Valve: The valve is used to inflate/deflate the inner tube. There are two main valve types available; Schrader and Presta. It is quite easy to identify from looking at your existing tube what kind of valve you have. Presta valves are narrower and longer, while Schrader valves are shorter and fatter (also found on car and wheelbarrow tubes).
