If you're trying to stop in the shortest distance possible in an emergency, over clean and dry pavement, using only the front brake does the job best, if not, with the most reliable results.

Just because the hypothesis had the misfortune of being presented by LarrySellerz does not discredit it.

There's many reputable sources on the internet saying the same thing about front brakes.

I'd still have rear brake on my bike though. If you're not braking hard enough, the weight transfer won't be huge and it would be better to use the front and rear brake together so you don't over-use the front brake.
