What is the difference between a road bicycle tire size 700 x 23c and I 700 x 23 I've been riding road bikes for years but really wasn't too aware that there appear to be two different tire sizes, for example a 23C and a 23. ( 700 x 23. And 700 x 23c )
700x23 and 700x23C and 700C x 23 and 700x23c and 700x23c all mean the same size of tire.
