Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

a logical jump would be to a 15 tooth cog in the rear.

Unless your gear is way too easy I'd be wary about that big a jump. You'd be adding 5 gear inches by dropping one tooth in back (6.7% increase). If you instead went to a 45 in front it would be a 1.7 inch increase (2.3% increase) or a 46 for 3.3 more gear inches (4.5% increase). More expensive to change chainrings than cogs (unless you run road rings and can find something cheap or semi-used, etc.) but gradual changes tend to be better for the body.

yeah, even if it's fine, work on your spin and eventually you'll just feel the time to move. part of why i'm into the idea of singlespeeds and fixed gears--even with my geared bike, i rarely ever change gears for this reason. stick with it, move up sometime later.

Winter slows you down ... keep the gear and move up by mid spring

My winter gear is 71" ... my summer gear is 86"

thanks dub! see this is the **** i don't know all that much about bein' mathematically illiterate. i look in forester's book and sheldon brown's site but i just need it put into plain english. guess i'll get a 45 since like you say it's a more gradual change. again, thanks.
