How big do you choose for your own mountain bike inner tube, and what do you think?

The model number of the inner tube of the bicycle will be marked on the outside of the inner tube of the bicycle.

What size the inner tube is used depends on how thick the outer tire is. It's not about the size of the circle. The size of the outer tire can be found on the side of the outer tire, which is the diameter (inches) of the inner and outer tube.

The diameter of the 26-inch rim should be about 66 cm, 26 inches (rim diameter) x inches (the diameter of the inner and outer tubes after full inflation).

Indicates a 26-inch rim that can be fitted or included with inner and outer tubes.

Brown's rule for tire size:

If two tires are mathematically equal in size, and one uses the decimal system and the other uses fractions, then the two tires cannot be used interchangeably.

Sometimes tire manufacturers even make a fuss about this issue. In particular, some European models were also mislabeled, using fractions incorrectly when they should have used decimal nominals.

The purchase of the size and specifications of the bicycle inner tube: the size and specifications should be matched with the outer tire, and the tire wall will indicate the size, such as: 26 refers to the matching wheel diameter, mountain bikes are generally 26 inches, and children's mountain bikes are generally 24 inches, referring to the cross-sectional width), 700 23C such words, to choose the inner tube according to the size of the outer tire.

Generally, there is a suitable range for the size of the inner tube, for example, the inner tube marked with 26 means that the inner tube can be used with 26-inch outer tires with a width range.

The wheelset is generally pasted with a sticker, which will say 26 xx, this is the size of the wheelset, how big the wheel is to choose how big the inner tube, and some outer tires will also write the size.

On the side of the outer tire, there are some numbers, such as the like, that represent the size of your inner tube. Look at it, you look like you're going to change your tires.

The model number of the inner tube of the bicycle will be marked on the outside of the inner tube of the bicycle.

For example, the following diagram illustrates a set of numbers: 20; 20 of them means that the inner tube is used with 20-inch wheels (rims); Indicates that this inner tube is suitable for use with tires with inch widths.

Here's how to choose a mountain tire size

1. The first thing to know is how big your tires are. The normal tire number is.

2. The number of braids per inch, the braiding density is worth noting the tpi, the higher the tpi value, the smaller the rolling resistance.

3. In order to withstand low air pressure and high pressure, PSI uses a cylinder with a barometer to pump out air. Moderate pressure will make for a good riding experience.

4. bar: 1bar=It is what we often say that several gas tires are also marked, which is also an important data.

5. KPA: 1KPA= is also a reference value of KPA.

Tread selection:

Off-road: Choose a dispersed layout with large particles rising on both sides. This will increase the momentum of cornering.

City: Choose a granule with a compact layout. There is not much resistance to cycling in the city.

It refers to the height of the rim frame, as shown below.

The higher the number, the higher the frenzy, and the heavier the weight in theory.

Generally low frame high, tan sail suitable for undulations and climbs.

It is a comprehensive frame height, aerodynamics and inertia are moderate, suitable for flat road cruising.

Summary. Hello, the size of the inner tube should match the outer tire.

Hello, the size of the inner tube should match the outer tire.

My bike inner tube diameter 64, how to buy it.

Whether it's a mountain bike or a regular bike.

Ordinary bikes.

It can be used with a 26-inch inner tube.

It is possible to fit the width of the outer tire in the range.

Generally speaking, the larger the diameter of the wheel frame, the more stable it is when driving at high speed (the greater the angular momentum), and the smaller the diameter of the wheel frame, the more sensitive the response will be. The wider the tire width, the more stable it is when driving, and you don't have to be afraid of small stones on the road; The narrower the tire width, the less friction and the faster the speed. There are particles on the tires that can conquer more terrain, and the friction is relatively small; Although the friction of a textured tire is greater than that of a slick tire, it is less likely to make a splash.

The model number of the inner tube of the bicycle will be marked on the outside of the inner tube of the bicycle. For example, the following diagram illustrates a set of numbers: 20; Its 20 old dismantling in the middle hall means that this inner tube is used with 20-inch wheels (rims); Indicates that this inner tube is suitable for use with tires that are inches wide in jujubes.
