I'm getting a fixie on Friday, I know for a fact that it doesn't currently have brakes. I would like to have at least one brake on this bike as I will be riding it around campus and people/cars jump out from nowhere and I'd rather not hit them. Does anyone have suggestions for brakes and levers that are reasonably cheap (I'd like to spend less than $60 total)? I'd rather have a brake lever that's somewhat low profile and can be operated in the drops (I'm there most of the time, more control you know). Thanks for the suggestions.
