    I'm not from boston, but why not go to 44/15?

    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.

    Keep it how it is. Work on your spin.
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    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.
