The new SC45 evolves the concepts of previous versions and bring the latest version of VISION rims, also used in the METRON range, but with more classic and less extreme construction solutions. In particular, the carbon rim with an aerodynamic profile, available with a depth of 45 or 60mm, features a 21mm internal width with hook to achieve maximum efficiency with tubeless tires ranging from 28 to 32mm. The 24 aerodynamic spokes with a 2:1 cross are laced onto direct-pull hubs. At the rear, the freehub is of the classic pawl type but in an improved version, without bearing preload adjustment but with pressure caps, to make the wheels more reliable and maintenance-friendly.
