im a (typically) a designated roadie (i like gears) but i live in the northwest. and it rains. ALOT. i've heeeeaard...that fixies/single speeds are good in wet or icy weather, and they just handle better than bikes w/gears. also, what is the difference between fixed gears and single speeds? i've seriously been thinking about getting a fixed gear, or making a road bike into a fixed gear. what would i have to do to accomplish this? im pretty darned tachy with bikes, it sounds easy enough to 'convert'.
