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? As well as coming in pretty colours, latex inner tubes offer lower weight and rolling resistance than butyl inner tubes. They’re relatively expensive though and heat build-up can cause issues if you’re using rim brakes on long descents.

Tyre Size Guide

You’ll probably see loads of tire sizes available when you look online. Unfortunately, as we’ve seen, tires that are only ‘close enough’ to your actual tire size most likely won’t fit your wheel rims correctly. This will often lead to issues such as punctures. You may need to choose between (i) which brand to buy and (ii) how much ‘tread’ or grip you want the tires to have. For bikes that will just be used on the road, I’m normally a fan of smoother tires. These will be much faster-rolling and give you less vibration as you ride along. However, if conditions are likely to be slippery, it’s a good idea to swap to more knobbly tires for extra grip. If you have carbon rims on a bike with rim brakes, you also need to be careful not to drag your brakes on long descents because overheating can cause latex tubes to fail. Some wheel makers recommend against using latex tubes with their rims. There is some overlap in sizes between 650b gravel and mountain bike tyres, but gravel tyres are usually sold in metric sizes as listed above. Bigger tyres naturally require bigger inner tubes. On the left is a 700×32-47C inner tube, while the right is a 700×18-28C. Simon Bromley/Immediate Media For even more weight saving, latex tubes are significantly lighter than butyl tubes, plus there’s less friction against the tyre, resulting in lower rolling resistance.

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?

There’s a range of lengths available: Zipp for example makes extenders from 27mm up to 98mm long. Please Note: any reference to 'Royal Mail 24 ™' and 'Royal Mail 48 ™' are Official Royal Mail Service names and should not be interpreted as '24 Hour Delivery' and '48 Hour Delivery'. The following sizes are common for mountain bike tyres, regardless of whether your bike has 26in, 27.5in (650b) or 29in wheels.

There are a range of excellent 700x35c bike tires and the one shown in the picture above is a great example. This is the perfect size for your tires, and has low rolling-resistance combined with high puncture-protection. An excellent combo.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? Valve extenders screw onto the top of the Presta valve. Some are just hollow tubes, others include a valve at the top, which means that you need to remove the valve core from your inner tube before screwing on the extender.
