<< Need help. What does the 700 c actually mean, as they don't seem to measure out at 700mm. How does this size compare to a 27"? Are there diameter variations to the 700c size as there were in a previous string regarding the 650's? Variations to the 27"? Would most any Campy rim be 700c, or 27"? >>
I am sure that you will get a more scientific response but I am under the impression that 700 c actually was originally meant to be 700 mm in diameter but tires have become smaller these days and are really more like 680 mm in most popular applications. I do not believe that there ever were any Campagnolo labeled rims in 27" size.....
