What size inner tube do I need for a 26 wheel?

The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125″, indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.

What are the 2 types of bike valves?

The two standard valve types are Schrader and Presta (photo). Schrader valves are identical to those found on car tires. These valves are generally used on hybrid and children’s bikes.

What’s a Schrader valve look like?

A Schrader valve consists of an externally threaded hollow cylindrical metal tube, typically of nickel plated brass. In the center of the exterior end is a metal pin pointing along the axis of the valve stem; the pin’s end is approximately flush with the end of the valve body.

What’s better Presta or Schrader?

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.
