Frame sizing
Hi folks, a quick question for you... how would you determine a frame size if you were upgrading from say a 56cm trek to a pinarello prince? I want to order online but don't know what size i would need seeing as it's a different design. any help appreciated! Greg

Go to the websites. Compare geometries.

Post respective geometries and we will try to help sort it out. Also report any fit issues you may feel with the Trek. Trek's run a bit different in size generally because of where they take the seat tube measurement which will be apparent if you post their picture with geometry table.

The most important thing is the virtual top tube C-C measurement.
Also important is the seat tube and head tube angle.
Also important is the Head tube length.
What part is confusing you?
They both measure the seat tube length from different places.
It looks like the Trek is going from the center of the BB to the top of where the seat tube clamp is.
The Pinarello looks like they take it from the center of the BB to the middle of the top tube.

Try https://www.bikesuperhub.net/bikefit/form2.html. If you know your current bike setup and the measurements of a new frame size, it will help you calculate the correct stem length, stem angle, spacer height and seat tube length for the new bike.
Or if you have the patience try https://www.bikesuperhub.com/bikedesigner which will allow you to draw the bike and rider and display all the dimensions.
