The idea dates back to the old days when you would ride out to the track on your racing bike, the bars would be on top of the stem to give you a more upright position for riding on the road.Your racing wheels were carried on 'sprint carriers' alongside the front wheel. When you got to the track you would change the wheels, take the brake off and move the bars underneath the stem and further forward. Then you were ready for racing.
