Abstract
The paper describes a novel Clench-and-Release Device (CRD), which can be used to quickly replace the rear wheels of bikes equipped with disk brakes, while also being suitable for front wheels. Since a quick wheel replacement is a pressing demand during competitions, the CRD reduces time wasted in situations like flat tire replacement. At the same time, it can be useful also for amateur bikers, who desire a simple way to lock/release a wheel without the risk of getting dirty or being unable to properly align the brake’s disk and pads. In fact, thanks to the CRD, both brake and pinion packs are kept in place at all times and the chain remains engaged with the gears, even after wheel removal. Although similar devices can be found on the market, the proposed CRD provides an improved design since: (i) pinions and brake are placed on the same side with respect to the wheel symmetry plane perpendicular to the wheel axis of rotation; (ii) the front and the rear wheel share the same hub; (iii) manual operations are definitely easier; (iv) the wheels are compatible with different types of transmission; (v) the brake discs are more protected in case of crashing. A patent for the Italian region has been filed.
