27.5" Nimbus Oracle MUni Unicycle - Racing Green
27.5" Disc brake Muni ready to go! This unicycle is both light and strong with a brake that does not grab in the way that rim brakes do so offering great enhancements in performance.
The 27.5" Oracle Unicycle with a Disc brake installed as standard. The design is aimed at the serious unicycle rider, offering design advantages that help exceed riders current performance. The Oracle has a lightweight but very stiff Aluminium frame with a durable powdercoated finish and smart looking decals to finish it off. At the heart of the Unicycle is the Nimbus disc hub, which allows the disc brake rotor to be mounted inside the frame, keeping it as far away from your foot or rocks as possible. With the super strong deep box section of the Dominator II rim this Unicycle will take anything you can throw at it.
