The regulation frame made of 28 mm diameter tubers has a traditional shape and carefully designed accessories that are machined from solid. Particular attention (involving computer analyses and track tests) has been paid to the construction of the moveable pedalboard, which is essential for adapting the chassis when drivers grow taller. The pedalboard is secured to the box that supports the steering column, moving back and forth along it depending on the driver’s height: an essential characteristic in a class like the Mini in which racers are growing constantly.
