this seems such an obvious query (to you lot) i feel stupid asking, but i really don't get what CTC and CTT mean in frame sizing. Can anyone help. I mean I've read the descriptions i've found on google, but i still don't quite get it. How can they both be the same, as they are on some bike ad listings?
