Thanks Ben
My new bike does have a little slope to the top tube, so that makes sense why I am measuring it a 57.5cm and not 60cm

My old bike (Felt 45) is horizontal
Guess it is a 56cm after all

I bought a 60cm based off of the idea that my old bike was a 58cm
All if fine though, I like the fit of my 60cm

I just want to make sure I am listing the size properly for whoever buys it
