Sector 9's Gullwing Sidewinder trucks have 10" axles. The patented design of the Gullwing Sidewinder Trucks have been turning heads since they were first introduced. What makes these trucks so special is that they have two pivot points which allows the trucks to turn twice as sharp and fast as a standard truck. This double action pivot allows the rider to generate speed using their own turning momentum. The Gullwing Sidewinder trucks are a sidewalk surfers dream. Ask anyone that has ridden them and the truth will be told.
