    Inner tubes

    Most inner tubes are made from butyl. Some delicate lightweight ones are latex. Like tyres, tubes come in different diameters (26, 27.5, 29 inches for mountian bikes, 700c for road bikes) and different volumes. It’s best to get the inner tube volume that matches your tyre width. Inner tube valves come in two sorts: schraeder and presta. Most keen cyclists prefer presta as they’re more precise in operation. Schraeder valves are more common on entry level bikes. Some rims won’t accept schraeder valves. All rims accept presta valves. We have lightweight tubes, tubes with extra long valves for deep section rims and multiple bundle deals for saving money by stocking up.
