if you have a deathwish, run brakeless, unless youre just going to putz out of your loft on like 55 gi and lock up in front of the bar or better yet drive from the suburbs with your bike in the back, park somewhere and take it out and ride around the corner to the bar.... if youre riding fast, and if youre riding distances, id recommend at least a front brake, and also knees get tired, and wallets get tired of buying tires
so basically everything everyone else said but less funny
