What does the C mean on inner tubes?

The first value, 622, is the bead seat diameter in millimetres. The second value, 19, is the inner rim width. The letter “C” indicates that the rim is the crochet type – the most common rim these days. (Note that those parameters describe the rim rather than the tire.)

What does 700×25 28C mean?

At one point in time, “700c” was a standard tire/rim size, where “c” indicated the bead seat diameter and “700” was the diameter, in millimeters, when the tire was installed and inflated. That “700c” tire size has a 622 millimeter bead seat diameter.

IS 700C same as 29?

29″ (ISO size 622) is actually the same rim diameter as 700C, although most 29″ tires will not fit 700C road rims because they’re too wide. 29″ tires are popular with mountain bikers; search for 29″ MTB. 650B (ISO size 584) is used for some randonneur bikes and other specialized bikes.

What’s the difference between 700x25c and 700x28c?

In short – the 700x25C is a French nomenclature for tire size meaning tire diameter of 700mm and tire width 25mm and C is the width of the rim (A is very narrow, D is wide). Thus the number between “x” and “C” is the tire width in mm.

What does a 700c bike wheel mean on a tire?
