I've just been doing some hill repeats and killing the boredom I got thinking, what is the best position to be in when braking hard (emergency stop, coming downhill etc.)? Obviously you want to keep the back wheel from lifting off the ground.
For example, I could lean over the handlebars (stupid but its illustrative) sit in the middle of the saddle, sit on the back of the saddle, or hang off the back beyond the saddle...
What is the most effective way to transfer weight on to the back wheel?
