You have 35 mm of spacers on your current bike I think? Reach is at top of headtube, so given headtube angle, adding spacers for a given stem length moves the bars towards you. Without info on your stem angle as well, it’s hard to give you the exact numbers.
The geometry there is saying 15 mm of spacers and and 80 mm stem would put you in the same position relative to your saddle as your current set up.
So a 56r would require a big spacer tower (more than 35mm)? Or just 35mm with a 100mm stem…? Therefore being almost exactly the same in appearance to the Genesis
