Consider these wheels as the most versatile of our road lineup.

They are an excellent combination: stiffness, lightness, quickness and aeodynamics for a really wide range of uses.

The low-mass 46mm medium-high profile rims give excellent reactivity under acceleration and help you mantaining the quickly reached speed with a considerable aerodynamic effect.

Razor edge handling with predictable reaction under change of direction.

Internal Nipple layout reduces air resitance during wheel rotation and enhances the overall areodynamic effect of the wheel.

The hexagonal Ergal nipples feature nylon thread-lock that enhances lacing stability and minimize trueing maintenance.

The surface material of Edge Composite rims enables unparalleled braking performance, dry or wet.


Straight pull spokes increase sprinting reactivity and wheel stiffness with considerable weight reduction.

Both front UltraFront SPM and UltraRear SP hubs feature external "Micro Tuner" system.
The precise "Micro Tuner" action is very easy to operate, it ensures perfect hub bearing setting.

Result: low bearing friction and no-play at the rim.

Extra wide camber enhances lateral stiffness with no weight penalty.
