I've read some reviews about this bike or that bike and some of the responses about the brakes got me wondering. What do people expect out of their bikes brake system? Do people want a quick controlled stop or do they want to have the brakes lock up and get sent over the bars onto the ground tumbling like Evel Knievel? what makes a good/better/best braking system? Pads? Pads and rims? Geometry of the mechanism?
