Which is the appropriate top-tube length?

Hi to all,

im relatively new in road biking and i want to upgrade my frame to a better one in order to use as a fitness (and maybe later with my dropbars) road bike. My main concern is what frame size to choose and on what measurements i should count on. My height is 170cm with a standover height of 76cm. My previous road frame has 46cm seat tube and 52cm horizontal tube (both tube and effective length) and a sloping geometry but i dont feel comfortable on it. What should i measure in order to calclulate the neccessary top-tube length?

I am now in light of buying a Cube Agree Pro (alum) frame and im between (theoritical) sizes 50 and 53.

Any ideas?

The only way is to go to a Cube stockist and size yourself up for an Agree -> you need to find the size that your are comfortable on.. which you can't do by other peoples recommendations.


For example i'm 6ft so i could have either gone for a Large sized giant, or a medium/large sized giant... if i had bought it blind online i would have bought a large which would have been too big for me... one trip to the bike shop to have a sit on a few different sizes and it was clear the M/L was the best size.

This. You are probably a 53 but go to.a shop. Cube sizes are a bit funny.
