Valve Type:
Schrader Valve(Length:34mm/48mm)----
Schrader (also called Standard) valves are the most common valve type for bicycles. This short, sturdy valve is also used on car tires and other inflatables. Typically found on BMX,Cruiser, Kids' and most Mountain bikes
Presta Valve(Length:36mm/48mm)----
Presta valves are typically found on performance road and mountain bikes(Tires that require high air pressure). They have built-in valve locks which you twist to open before inflating.
Tube Size:
26" x 1.9-2.125, 27.5" x 1.95-2.125, fit 26-inch/27.5-inch wheel, tire width between 1.9-2.125. To determine the size you need to check the side wall markings on your tire where you’ll see two numbers separated by an 'X'. The first number refers to the tire’s diameter. The second number refers to the tires width. Select the tube that has the exact same diameter as your tire. Your tires width should fall into the range of widths listed on the tube packaging
Attention:1.Please kindly confirm the size of your bike tire before you buy.
2.Before changing the tube, please check whether have some stones or sharp things that may broke the tube that stay in your tire.
3.Remember to always add a little air (to give the tube form) to the new inner tube before installing. This will prevent it from bunching up and/or causing a pinch flat or possibly blowing the tire off the rim (when you immediately and fully inflate) which ultimately will pop the tube.
4.Never over inflate past the recommended tire pressure.
