Why does my inner tube keep splitting?

Punctures are generally caused by a small, sharp object (flint, glass, thorns) poking through the rubber and piercing the inner tube. Quite often the item stays lodged in the tyre – so if you don't locate it and remove it, when you replace the inner tube it'll only be quickly deflated by the very same little blighter.

Can I drill out a Presta rims for Schrader tubes?

You can convert schrader to presta but not the other way around. Don't drill your rims. The metal is so thin on rims I'm afraid you could make some major damage and then your rim will not hold up on rough riding. not true - they make grommets that allow you to put a presta in a schrader hole.

Does Presta valve size matter?

Yes it's the length. Longer valve is for deeper section rims, so look at the valve length you have now and whether it needs to be longer. A longer valve stem than needed won't hurt anything.

How tight should Presta valve nut be?

If you want to use the nut, inflate and lightly tighten it down after inflation with your fingers (there are some other schools of thought on how to use them, but this is probably the simplest). Don't over tighten it or you'll damage the tube.

Why are bicycle tubes so bad?

Most inner tubes are made from rubber and inflate with air, therefore, anything sharp, including thorns, glass, rocks or nails, can cause damage to the inner tube and allow the air to leak out. We've just reduced the price of our 71 page 'Bicycle Commuting Handbook' by 50% for a short time.

What is rim tape?

The purpose of rim tape is to protect the bicycle wheel's inner tube from spoke holes, which will puncture the tube if exposed inside the rim. ... Rim tape is available in a variety of materials (usually rubber, adhesive cloth, or tough plastic), and it comes in various widths and diameters to fit different wheel sizes.

Are Presta or Schrader valves better?

Presta valves are easier to pump than Schrader, because they have no valve spring to overcome. ... In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves. In contrast Schrader valves are more robust, universally used, and have an easily removable core.

Can you convert Schrader to Presta?

Do I have a Schrader or Presta valve?

Presta valves are more commonly used on skinny road bike tires because they are narrower and require a narrower hole in the rim. ... Presta valves adapt to higher pressure than Schrader. Road bike tires often exceed 125 pounds, while Schrader tubes top out at about half that.

What's the point of Presta valves?

So to sum up, the advantages of Presta valves are that they allow a higher air pressure, require a smaller hole in the rim and can be purchased in various lengths to suit the profile of your rims. It's very unusual to see Schrader valves used on road bike tubes and wheels.

Are there different Presta valves?

There are two basic types of valves that you'll find on bikes: Presta and Schrader. For the most part, inner tubes and tubulars on road bikes will use Presta valves, and mountain bikes will use Schrader valves.
