The humble inner tube may be one of the simplest parts on your bike but with a wide range of sizes different valve types and a choice of materials choosing the right tube isn t necessarily as.
Bicycle inner tube valve types.
These valves are quite narrow and have a screw at their valve tip.
Presta valve inner tube.
Most bikes come with wheels that use presta valved tubes.
Bicycle tubes with presta left and schrader right valves.
Bicycle inner tubes have two major types of valves.
The first two models are the most common among bike tubes and they function in the same style.
Schrader presta and dunlop or wood style.
If you have deep section rims make sure the valve is long enough to extend through the rim hole and still leave enough valve stem showing to fit the pump onto.
Bicycle inner tubes are divided according to their valve types and there are three of them available in the market.
Wider than a presta valve and typically the same circumference top to bottom.
Presta schrader and woods valves are each most common on particular types of bikes but they function largely the same and are frequently but not always interchangeable on wheel rims.
A third rarer type of valve is the woods or dunlop style.
