well, here's just my opinion on bike brakes, I use the back brake only when im trying to bleed of speed, like while in a corner, and both when im just trying to stop (more in the front). I always shift my weight back to compensate the stopping power of my front brake (a habbit from MTBing and not wanting to faceplant on a rock) and I'll even sometimes go to the extream of putting my saddle in my gut on a steep decent when stopping fast is important. It's amazing the stuff you can apply from a single track on the road, ever hop a pothole? Guess where I learned it. Just hope I don't have to get over a log in the road
