From www.sinz-racing.com; ''In Spring 2008 SINZ is proud to offer the most technologically advanced fork in BMX racing. Our R&D team has developed the Stealth Fork from the ground up. This fork just oozes style with hand laid carbon legs, forged dropouts, forged crown, and 1-1/8” CNC steer tube''. These forks are also lighter than the Answer Scythe.
