Red Bull Quarter Master

Sebastian Keep has built and ridden one of the biggest dirt quarter pipes ever made, reaching heights of more than 45 feet. This September he returns to Wales, to a new course, built to push him and eleven others riders to new limits.Towering at twice the height of a double decker bus and taking around four months to complete in late 2013, the idea to build the quarter pipe came to Bas around five years ago when he approached Red Bull with a sketch on a piece of paper. This year, he has added new features and invited the best riders to come down and ride with him.
