I commute with 76 gear inches. My commute has some gnarly hills, so I don't want to gear it any higher. However, that other side of my hub is beggin for another cog. I sometimes do flatter rides where it seems I'm just spinning out and I'm sure I would be going faster with a few more gear inches. Trouble is, I'd actually have to stop and flip it around...OK so maybe I'm whining, but I'm just curious if any of you actually ride around with two cogs on your flip/flops and how often you switch em around.
