Inner Tubes

Bicycle inner tubes of quality are worth having!

Inner tubes are available in three value types:

• Presta / Racing
• Schrader / Car / Auto
• Woods / Dunlop (these are actually still the most popular worldwide, but not used much in the UK)

Good quality air tight tubes have to be inflated less. This means you can get straight on with your ride, rather than messing around inflating the tyres before you can start. (or have an extra 10 minutes riding / in bed)

Schwalbe tubes use the following prefix for different type of valve:

AV = Auto Valve - The wider valve generally used on lower end bikes and on Brompton folding bikes - these are in a blue box
SV = Sclaverand Valve - Referred to as a racing / presta valve in the UK - these tend to be used on higher end bikes where thinner / lighter wheels needed a narrower valve - these are in a red box
DV = Dunlop valve - not so common now, as they are a bit more fiddly to look after - these are in an orange box and are becoming less available

Presta valves come in different lengths (they may vary slightly by manufacturer):

40mm - the normal / common presto valve length
50mm - long length
60mm - extra long length
80mm - extra extra long length - for deep carbon rim wheels
