I understand the logic behind this statement, but think that cyclists are better served to use both brakes. First, there is a period of time for the weight and traction to be transferred to the front wheel. During this period of time, the rear wheel is rolling and in contact with the road, available for braking. Why ignore it? it might be 40% of your braking power very early on? Secondly, lets say you are going 25 mph and need to stop quickly. Do you really think you can do a "stoppie" from 25 mph down to zero? I know I can't. The best I can do is get the rear wheel off the ground for the last few feet. Up unitl the end, that last bit where I finally get the wieght and traction all the way onto the front wheel, that rear wheel is helping me stop.

But I whole heartedly agree that if you are going to use only one wheel, it should be the front. And if you can ride one wheel all the way to being stopped, then I guess you know what you are doing, and are just worlds better at it than me.
