I haven't been riding fixed long. I already have a fairly low gearing. There's a hill near where I live that I just cannot get up. So, should I just keep riding with the gear I have and hopefully build strength that way, or, would it be better to go to a lower gear? Most hills around here I can get up, but its slow and out of the saddle a lot. Also, for what it's worth, I'd characterize the hills as short but steep.
