How do you guys manage those crazy hills on the uphill journey with anything 48x16 or over? Legs of steel and super hard mashing or what? Or do you walk your bike up (shame on you). I roll 49x19 in Portland and it seems to be a good uphill and downhill gear though I'd like something higher for downhill (but it's great uphill), but it's all a matter of knowing your technique / limits when you reach higher RPM's, and small skip stops on the really long hills help too. There is a few really big hills here that I think could rival SF, too.
