Vittoria Standard Butyl Inner Tubes - Inner Tubes for Road and Track Bikes - Presta Valve - Synthetic Rubber - 0.9mm Thick Inner Wall - Black

Product Information

If your wheels are even deeper than the longest valve you can find, you can buy valve extenders to add length to your valve. There’s a range of lengths available: Zipp for example makes extenders from 27mm up to 98mm long. On the other hand, they’re much more fragile and more awkward to fit as they’re floppier than butyl tubes. The former are simpler to use, but add a dead space above the valve, making inflation harder, while with the latter you need to make sure that there’s a fully airtight seal to the inner tube’s valve stem, or your tube will leak air.

In a nutshell 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. On bikes, Schrader valves tend to be used on lower pressure tyres, such as kids's bikes and mountain bikes. These are the same valves used on all motor vehicle tyres and are often referred to as ‘car type’ valves. Schrader valves have a core that is sprung loaded, and the central pin can be depressed with a narrow object to release air from the tube. The spring mechanism keeps the valve closed.

Valve extenders come in a range of sizes, types and even colours. These ones simply screw over the top of an open Presta valve, but you can also get ones that allow you to place the valve core at the top. Simon Bromley/Immediate Media 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.

Inner tubes are simple but essential – unless you’re riding with tubeless tyres, you’ll always need an inner tube. Carrying spares is always a good idea, even if you are running tubeless, as a large slash or hole will not seal easily.

They’re relatively expensive though and heat build-up can cause issues if you’re using rim brakes on long descents. Simon Bromley/Immediate Media
