Diameter x Width The first number is the diameter of your wheel. Longer valves are designed for use with deep section aero rims. Punctures are inevitable.
Instead of having to lug around spare inner tubes with you, you can opt for a self-sealing inner tube. These bike inner tubes are delivered with tube sealant already inside.
When you get a puncture the sealant will plug the gap so you can keep riding. Tredz is a trading name of Performance Cycling Ltd.
All Rights Reserved Company No. Some presta valves come in one piece, while others have cores that unscrew from the valve body.
You can often unscrew them by hand or by wrapping them in a piece of old cloth or rubber and delicately using a pair of pliers. There are also core removal tools available.
A removable core can be replaced if it gets damaged — the screw part can often end up bent. The disadvantage is that you can unscrew the core by accident when removing a screw-on pump, undoing all your hard work pumping the tlre up.
Some tubes have Schrader valves like those used on car tyres. More of a rarity is the Woods valve.
This looks like a presta valve, but has a collar holding the valve core in place. Not all modern pumps will fit onto a Woods valve because of the collar.
Finally, keep an eye on the valve length. Some valves can be as long as 8cm.
If your valve is still not long enough for your deep section wheel, you can buy valve extenders. These screw onto bike tire tube size chart skate bikes and can add enough extra length to fit the deepest aero wheels. The majority of inner tubes will be made of butyl rubber. Schrader valves are the same slze found on most cars and motorbikes.
Larger in diameter they require a larger opening in rim than Presta valves. Dunlop or Woods valves have the same diameter valve as Schrader types but use a removable flange to secure the valve in place. They can be aize by Schrader valves without modifying the rim.
For comparison a standard length tends to be around 40mm. These little widgets add length to the valve stem.
Some screw over the top and others require you to remove the valve before fitting. If you buy posh wheels they usually come with them included.
Most tubes are made of butyl rubber.
