Q & A
* What size inner tube should I choose for my bike?
You must make sure you replace your inner tubes with a tube that is the right size according to the diameter and width for your tyre. The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125", indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.
* What Are The Different Valve Types?
-【Schrader Valve (A/V)】 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. If you plan fast downhill riding, there are tubes designed for slamming into rocks and obstacles. -【Presta Valve (F/V)】 Presta valves are valves which have a slimmer stem, sometimes threaded to accept a locking ring, which holds it tight in the rim drilling. They are usually found on higher pressure tubes such as on a road bike. To inflate or deflate a Presta Valve, the top section must be unscrewed, allowing the core of the valve to be free to move. This will allow the valve to open and close. In this high pressure valve, it is the air pressure that shuts the valve and then the closing of the top section that keeps it shut.
* How can I choose the right valve length?
Inner tubes are available in different valve lengths to be appropriate for use in deep section rim profiles. 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. Valve extenders can be purchased to make a shorter valve fit and are also a good idea to carry as an emergency spare if you know your tubes require it.
