Just in time for the Pumptrack World Championship, Billy Bonkers is also starting to race. Schwalbe s new pro fil for pump track, dirt jump and slopestyle has what it takes to be the winner: the 490 g extremely light tire not only rolls off extremely lightly, but also runs very playful and agile. At the same time Billy Bonkers offers his drivers a good-natured behavior during landings, even after mock tricks and jumps. Its pro fildesign is designed with maximum micro-toothing on crushing sand and on hard ground and forgives even coarser mistakes.
