i ride brakeless because there weren't any brake holes on my main bike when i started riding it. then when i replaced the fork i decided to keep it that way for safety reasons. my main bike has a smaller front wheel, and i think front braking only would flip me. it also looks cleaner. on my "rain" bike, i could run brakes, but i just don't out of stubborn-ness and stupidity. there are some days when i wish i had a brake on there, but for the most part my gearing so esy enough that i don't have a problem stopping. i also think that a brake on a fixed gear makes me lazy about paying attention to traffic.
