The inner tube is an essential element of the bike, which is responsible for efficient and smooth ride. The key is to correctly choose the type of inner tube and its size. It is also worth to buy patches for inner tubes, which are a good alternative when cycling for a spare tube.
Tube - how to choose?
Individual bicycle tubes differ in width, size and are made of other materials. Choosing the right inner tube should coincide with your preferred driving style and type of bike - mountain, city, road or city.
In order to purchase a new inner tube:
- verify the size of the inner tube - by checking the size of the tire earlier
- check the type and length of the valve - then select the same valve
How do you check the inner tube?
If you suspect a leak in a bicycle tube, it should be checked immediately. For this purpose, one of two methods can be used:
- inflate the inner tube and listen to where the air escapes from
- dip the tube in the water and observe where the bubbles are coming from
If the inner tube is actually punctured, you should not continue cycling, because it is dangerous and threatens to damage both health and exposes the bike to further damage. It's best to replace the inner tube immediately with a new one, or apply patches to inner tubes. If this is not possible, you must lead the bike on foot.
Inner tube what size?
The size of the inner tube depends on the size of the tire that appears on the side walls of the tires. Sizes are given in two ways: classic - diameter in width, or according to the new ETRTO designation - tire width and inside diameter. The size of the inner tube must be compatible with the tire, as well as the type of valve you have.
The most popular sizes of tubes are: tube 26 and tube 28 in bicycles for adult cyclists and for children's bikes 16 tube.
What patches for inner tubes?
An alternative to having a spare tube on each cycling expedition may be patches for inner tubes in various sizes. In addition to the patch itself, remember to take adhesive for inner tubes, a piece of sandpaper and a bucket for removing the tire. Another option is self-adhesive bicycle patches, which do not require the use of adhesive for inner tubes.
How do I stick a patch onto a punctured inner tube?
- use sandpaper around the hole on the tube
- put some glue in place with the hole and wait about five minutes
- remove the patch from the protective foil and also apply the glue on the patch and wait for a while again
- after the time when the glue is a little dry, stick the patch on the tube and hold it together for two minutes
- a sealed inner tube can be gently put back on the bicycle and then inflated slightly
- after verifying that the air does not go down, all you need to do is put a tube in the tire and inflate it
In addition to patches for tubes, you can also optionally use a tube sealer, a puncture protection band, and even choose an inert tube from FOSS.
In conclusion, the inner tube is an essential element of the bike, which should be well-matched to the specific model. The size of the inner tube depends on the size of the tire and the valve you have. An alternative to the spare tube while driving are patches for inner tubes, thanks to which you can patch the hole. It should be remembered that you should not continue to drive with a punctured inner tube.
