wet-weather brakes
so here's the problem:
i'm a student and don't wanna spend much money.
but i want my bike to have at least one brake that'll work well when i get snow or rain on my rims. (i've got old-style rim brakes right now, and recently found myself using my shoe on the pavement to help slow myself down on a rainy day)
i'm sure i'm not the only one with this problem. any suggestions regarding cheaply getting my bike set up with a good wet-weather brake? know of any sources for cheap used bikes/wheels/whatever with drum brakes? or discs?
