Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Road bike vs TT bike

I ride a 56 in a road bike..meaning the 56 top tube is perfect...

what would I be riding in a TT frame? I see they are sometimes different for effective TT for the size I would think I am...

Was looking to get a leader this year and have no way to try it out...

So you are saying that your 56cm bike has a 56cm top tube? It almost sounds like you are saying your size 56 in a bike is talking about the length of the top tube, it is not.

sigh. I ride a 56cm Top tube.

It could me a Medium frame sized from the manufacturer, but the effective TT is 56. It could be a sloping 52, but if the effective TT is 56 - it will generally work for my road position.

it is my rule of thumb...

So giving you a little shorter top tube for the aero position you would need a 57cm leader TT frame. That has a 54cm top tube.

Go get fit by someone that knows what they are doing. Even Pro's get tweeked every time they change manufacturers. But if you want my opinion, (mind you I have only fit people on Trek's TT bikes) I would say a Medium TTX or a 56cm Equinox 7 for Trek
