I just discovered last night that wheel size isn't really the wheel size???

Rather, it's an approximation of what you get AFTER you put the tire on.

So a 700cc wheel isn't 700cc until after you add a "typically" circumfrenced tire to it.

I discovered it because I was calibrating my kids bike computers and their tire sized didn't appear in the charts, so I had to measure.

Does everyone already know this?

It's a 700mm tire on a 622mm rim.

Do a roll out to calibrate the computers.
