Fulcrum Speed ​​Combo 42/57 DB wheels

The new Fulcrum Speed ​​Combo 42/57 are Fulcrum's first step into a new era and dimension of the brand, Form, Function , Fulcrum, in which form and function are the fundamental concepts.
An evolution without compromises: the new rims - taller, wider, lighter and more aerodynamic - the new hubs and the new spokes make up a perfect wheel system.
The new wider rims, coupled with 28 mm tyres, are able to offer an uncompromising performance combination, in which aerodynamic penetration, rolling resistance and comfort find their best expression.
The rim is made using resins and fibers made to Fulcrum specifications where, unlike previous versions, a new composite mix of unidirectional FF100 high modulus fibers is used for Speed ​​Combo 42/57. Thanks to numerous experiments, the perfect mix of fibers has been achieved, which combined with the correct positioning of the same and a very precise control of the resin, allows us to obtain a product that works in the correct elastic range, guaranteeing performance characteristics at the top of the category and a sensation superior driving.
