The ultimate structural accuracy of Mobirolo's expertise materialises in the shape that connects the two flights: a curve designed to let you change direction seamlessly. Harmonious shapes and a combination of curved features, the fruit of state-of-the-art technology and skills. Form and function: the harmony of the main construction is enhanced by the steady tread that makes for an easier climbing experience, with constant tread steps, a solution that translates into a one-depth tread, identical in the turning steps as well, with a constant gradient for a safe and comfortable use.
