Jake Seeley's signature frame is designed to complement his progressive, technical street riding. The Street Sweeper evolves directly from Jake Seeley's original Broadcaster frame by using shorter chain stays, a steeper head tube angle, a taller bottom bracket and smaller hollow dropouts with integrated chain tensioners. Built with versatility in mind, the Street Sweeper features removable u-brake hardware and Gyro tabs. The frame's front triangle makes use of traditional round Nightshift style top and down tubes with proven internal gusseting.100% 4130 Chromoly Frame.
