If you have time and enjoy some free technology you could draw your current bike on
BikeCAD free then compare that to Brand X RD-01 52 and 54cm; I've just drawn those up and added them to their
Design Archive.

If that appeals before you do anything
create your free account so that you can save your drawing when finished. You can start with either their
quick start drawing, or any from their design archive that includes mine above. Whatever drawing you start with in each case you can edit and save to your free account as your own drawing and keep it 'private' or make 'public' as desired. When you have found the drawing you want to start with simply click on the green "open in BikeCAD' tab, note as they correctly state "it can take several minutes to load". Although the free version as you'd expect offers less than their Pro Version if you draw up your current bike you may find it of use.
Normally the free version works best if you do not display the chain and rear derailleur, plus even though technically you can I would not try and upload any
brand logos as it is inclined to crash; adding text to frame and components as I have done in the example above is not a problem. I have a few tips on my own
BikeCAD blog that may help, there is also quite a lot of useful Videos they publish on
