A real race bike (made for competition) is unlikely to have a pump peg brazed on.
And there's nothing worse than needing to stop for a wizz during a race -- better to be a little thirsty than water-logged.
People tend to drink too much -- something I've learned after years living in deserts with nomadic tribes.
One bottle is good for 100 miles if used right and with some food.
