Screw the brakeless mentality. If you want a brake, do it. Ceya! has posted before that the (true) Keirin racrs never train on the road w/o a brake. Either they use the clamp system or they drill the fork.

I run a front brake but have only used it a handful (pun intended) of times. Sometimes its hard to account for the stupidity of cagers, myself included.

It is your bike, with your butt on the saddle, don't let the non-owner/non-riders of your bike dictate your comfort level.
