700 vs. 700c
I'm looking for tires for a set of 700c Zipp 808 tubular rims.
Looking at PBK they have the Vittoria Corsa Evo CX 700 x 21mm in black, while some other colors are listed as 700C x 21mm. I thought the letter (width designator) no longer mattered for tubulars. These are the same sizes, yes (700 vs. 700C)?
Thanks

The "C" designation is a left over from many yeas ago when 700A and 700B wheels/tires were also available. These days 700C is the only survivor so the "C" is really redundant.

Mr Riggs (my chem teacher) always said that numbers without units are just numbers.
I guess that they aren't actually tires at all, just numbers...

Bassplayinbiker....that is absolutely correct. In order to have a measurement one must have a number and a unit. I'm a HS chem teacher. That was actually a test question I gave them. lol!!!

These days the terms "700C", "650C", 26", etc. are really titles, not measurements. They define a wheel or tire type, not it's true dimensions.
