The Henry's Vision diabolo is mounted with a 'Free-Hub' bearing kit to create a sophisticated prop, ideal for people advancing up the diabolo trick ladder. The Free-Hub kit uses covered, grease-free bearings with a smooth roller to ensure optimal play. The extended spin times that this diabolo will provide mean far more complicated, technical trick sequences are possible. This Vision diabolo can also be retro-fitted with a fixed axle or any of the Circus Tuning kits if desired. Vision shells are made from hard-wearing urethane - the same material used on skateboard wheels. The cups are frosted, opaque colours apart from Black and White.
