Front brakes DO deliver waaaaaaaaaaaaaay more stoping power than the rear brakes BUT, if I had to choose one or the other, I'd definitely choose rear brakes ANY day... I'm way more use to slowing down and skidding to stops with rear breaks then with front brakes... Ex: Say an asshole driver cuts you off when you're biking... generally your instincts are to immediately slam on the brakes, right? slamming on front brakes wont help you much in a case liek that... that's just me personal opinion tho
