Has Aerodynamics Gone Too Far? Discover the Wilier Supersonica SLR
The Wilier Supersonica SLR is the ultimate speed, engineering, and aerodynamics machine in the world of professional time trial bikes.
Available in two versions, with rim profiles of 42 mm and 57 mm, the Speed Team represents an evolution of the previous Speed 42 and 57 models. While maintaining their established technical specifications, the new wheels introduce a crucial improvement: a lightened freewheel body with USB™ (Ultra Smooth Bearings) ceramic bearings. This competition-derived solution has been developed to further increase smoothness and efficiency, eliminating friction and guaranteeing an unparalleled ride feel.
The essence of the Speed Team wheels lies in technological innovation, while their bold design fully celebrates the competitive spirit. A new oversized logo with a metallic effect embodies energy, daring, and strength. The distinctive graphics express the passion for racing without compromise, from gran fondos to the most demanding stages of Grand Tours, underscoring the emotional connection between those who live to race and those who race to live.The technical foundation of the Speed Team wheels originates from the previous Speed 42 and 57 mm models, the result of over 4000 hours of research, development, and testing. Every detail has been meticulously designed to offer maximum reliability and racing-level performance. Key technical features include:
with an internal width of 23 mm, ideal for 28 and 30 mm tyres, which improve aerodynamic penetration by up to 10% and handling by up to 16% compared to the previous generation with a 19 mm inner rim width.
with an undrilled inner rim channel, which increases the resistance and stiffness of the rim, eliminating the need for tubeless rim tape for the use of tubeless tyres.
that provides an elegant look and ensures a perfect tyre fit
arranged with the Two-to-One™ system, which doubles the number of spokes in the areas of greater stress to optimise torsional stiffness and maximise power transfer.
with an adjustable cup and cone system, which guarantee superior smoothness thanks to the perfect alignment of the forces at play.
also equipped with USB™ ceramic bearings.
Each Speed Team wheel is assembled by hand in Europe, in compliance with the strictest quality standards that have always distinguished the Fulcrum brand.
