Okay, the gears are wide. Is there an advantage to setting up gearing so that one uses the middle gear (1:1 at the hub) mainly, or the high gear?
I'm commuting, it's fairly flat terrain, and using a bike with 7 rear, 2 front, I don't shift a lot; just depends on if I'm feeling perky/competitive or lazy/old, whether I'll use 52 or 42, and I stay mainly in the middle gears like 17, 19, 21. But even that 52/42 shift is a smaller change than between any two gears on the S-A hub. And, I prefer a fairly high cadence, compared to most people I see cycling.
