How To Buy Mountain Bike Tubes
Buying mountain bike tubes is not an easy task because there are many factors to consider like the size, type, quality, and the price.
The size of the tube depends on the tire size of your bike. The type of tube depends on how you want to use it. For example if you want to use it for racing then a lightweight tube would be good but if you want to use it for a casual ride then a heavy duty one would be better. The quality of the tube also matters because high-quality tubes last longer and are more durable than low-quality ones. Finally, you should consider your budget when buying mountain bike tubes because some tubes are expensive while others are cheaper.
How do I know what tube to buy for my bike?
The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.
How do I choose an inner tube for my mountain bike?
MTB tubes must be the correct width as well – also measured in inches. This is to allow the tube to expand to the correct size for your tires, and can range from as narrow as an inch right up to a tire width of 2.5″ or greater. If you had a 26 x 2.3″ tire, you would need a 26″ tube that can expand to a width of 2.3″.
Do bike tubes need to be exact size?
While your diameter measurement needs to be exact, your width measurement does not. Because inner tubes stretch, they typically come in a range of widths. For example, one of our most popular tubes is the 26 x 1.75-2.125” which means it fits a 26-inch diameter tire with a width in the range of 1.75 to 2.125 inches.
How do I choose a tube size?
The average size of the tube for an adult male is 8.0, and an adult female is 7.0, though this is somewhat an institution dependent practice. Pediatric tubes are sized using the equation: size = ((age/4) +4) for uncuffed ETTs, with cuffed tubes being one-half size smaller.
Will a 27.5 tube fit a 29 wheel?
Mountain bike tyre sizes are usually stated in inches. So a 29 inch MTB tube will have the same diameter as a 700c road wheel, while a 27.5 inch tube will be the same diameter as a 650b road wheel.
Will a 26 inch tube fit a 27 inch tire?
In real world applications, a 26″ tube will work perfectly fine in a 27.5″ tire.
What size valves do I need MTB?
According to this rule of thumb, low-profile rims that measure around 25mm require a 40mm valve stem. For those wheelsets measuring 35-45mm, a 60mm valve stem will normally be long enough, while anything taller than 50mm demands an 80mm valve stem.
Is the inner tube the same size as the tire?
The tube should match the tire size diameter closely. However, tires that are close in bead diameter may use the same inner tube. For example, an inner tube for an ISO 630 tire (27-inch) will also fit an ISO 622 (700c) tire.
What does 700c mean?
700C tires The “700” refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern. The “C” means NOTHING; it does not stand for “centimeters.” Think about it–a 700-centimeter tire would be HUGE, over 21 feet tall!
What happens if you use the wrong size inner tube?
With a diameter that is too big (e.g. a 29” tube for a 27.5” wheel), the tube will be too loose on the wheel rim and you may end up with bunching in the tube rubber. This can lead to punctures. If the diameter is too small (e.g. 24” for a 27.5” wheel) it is unlikely that the tube will stretch around the wheel rim.
Can you put 25 tubes in a 28 tire?
Re: 20-25 tubes in 28mm tires?? It’s basically a no-no because as you pump up tyre the inner tube will stretch to fill the void of the wider tyre making it more likely to fail (or so the explanation went).
Are Presta valves better than Schrader?
Presta valves also perform better over time compared to Schrader valves, in that they hold air more effectively and don’t degrade as quickly. They can also hold higher pressures, which makes them a must for track cycling where tyre pressures typically exceed 120psi.
