I know it's a bit small for my height but it felt good, didn't really feel too cramped. Anyways. I'm deciding to pick up a cervelo p2t track frameset drone someone local here in hawaii. But its also a 52cm frame. Just wondering if I should picl it up, or should I find a frame size 54cm? I'm afraid that if I get it, it won't feel the same as my 52cm leader 721.
Unfortunately, you are comparing slightly different frame types. Cervelos have road TT geometry. Slack head tub angle, slack fork rake, steep seat tube angle, small head tube. You will just have to build the bike and see.
There is no real way to "do the math" and figure out how it will feel.
If the bike is currently built by the current owner, ask him/her if you can ride it first. If not, it's a gamble.
