There are many different types of inner tube available so it is important that you get the right tube for your bike and to suit the riding that you are doing. How would I choose the best inner tube for my tyres? The Dunlop valve, also known as a Woods is a variation of pneumatic valve that is rarely used on modern bikes. However they were once popular. They look like a cross between the two valves, with a wider lower section, like the Schrader, then a collar and a narrow top section, like the Presta. As the rim drilling is the same for both Woods and Schrader, it is easy to replace the older tubes with the more modern variety. How can I choose the right valve length? DO NOT use the size on the inner tube, always use the tyre specification on the side wall of the tyre. It's mainly because the tube inside the tyre may not actually be the right size (especially with second hand bikes). So, you'd be replacing the wrong tube again. Also, manufacturers can use a tube with limited size range (because it's cheaper) which then would limit your options of which other tubes you could use. So always get your inner tube size from your bike tyre! Butyl rubber is the industry standard for common replacement inner tubes, offering a relatively cheap and readily available replacement product. Butyl is strong and resistant, and there are lightweight versions for those looking for weight savings - the Specialized Turbo range and Continental Supersonic tubes are popular versions. What are the differences between Latex and Butyl rubber tubes?You must make sure you replace your inner tubes with a tube that is the right size according to the diameter and width for your tyre. The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125", indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches. On the tyre wall are usually two sets of numbers. Traditionally, English or Imperial Sizing has been used to find inner tube and tyre sizes. However, the best inner tube sizing method is done by using ETRTO sizing. ETRTO is an International Sizing Standard making it clear and simple to understand. For those who are interested it means European Tyre and Rim Technical Organisation. In our example we have both sizing versions. Other common conversions of Imperial to ETRTO sizing are below:

It’s highly frustrating to go to the trouble of replacing a tube…only to find that it punctures because your tire is too damaged to protect it. You’ll find a LOT of bike tires that ‘kinda look similar’ but, in practice, will likely not be the correct size for your bike. Best bet is to get a tire that has the exact reference number as on your existing tires (i.e. 26×1.95). Tire size differences can lead to problems down the road (literally).
