I got lazy on geared. When I started riding fixed on my 18 mile commute my time improved by around 5 minutes. My explanation for this is that I tend to try to maintain momentum on the flat to carry into the inclines, and when on the inclines I dig in and get on with them rather than finding a lower gear. I'm in no doubt that commuting on fixed has made me stronger when I return to gears. On a geared bike I find myself further down the block than I used to be. 48x18. The only downside is when theres astout headwind, it gets a bit gnarly on those days.
