The Odyssey Springfield U-brake turns the installation and adjustment of U-brakes into a quick and easy process that requires nothing more than a 5mm Allen key. By using a small center pull coil spring to attach both brake arms together, the Springfield brakes require no further spring tension adjustment. Cast aluminum arms help keep cost down without sacrificing brake stiffness and include Odyssey Ghost brake pads with integrated toe-in to further ease installation. Straddle cable, cable hanger and all necessary hardware included. For rear brake only.
