Years back living near hilly places 52-36 doubles were OK.

Now the old road rig got the same drivetrain ratios as the touring bike .. 50.40.24
just 13-28 freewheel rather than the 13-34..

just dont ride the roadie bike much , any more .. IGH convert..

Rohloff is at its minimum , 16:38 in a 26" wheel..

20" wheel 16:53 is comfortably with in the min range , could be lower..

11th [1:1 in the hub] is about the same relative with the ratio/wheel size ..
