High profile rims - Racing Speed

The rim

High profile rim for 50mm tubulars, enables the maximum aerodynamic penetration, reducing friction.
The design of the profile details makes the wheel extremely manageable even in a crosswind.
Exclusive pressing system for the rim in unpainted carbon enables an extremely limited weight and a smooth surface free from imperfections.

Hubs and flange

The cone and cup technology system with absolute performance.
Easy ball/bearing adjustment – reduces possible ball/bearing play – precision operation – maintains performance over time.
Aluminum hubs with oversize aluminum flange and Two-to-One™ technology to transmit all the power to the ground.
Aluminum axle reduces the overall weight of the wheel.

Racing Speed - Oversize flange

Oversize flange

Oversized flange on the drive side provides greater torsional stiffness, increasing reactivity at any change of the rhythm of the pedal stroke.

Spokes and nipples

Aero spokes (18 front, 21 rear) in stainless steel with variable cross-section, doubled on the drive side(Two-to-One™).
Aerodynamic profile in steel ensures the maximum aerodynamic penetration and, thanks to the material employed, lower weight and greater reactivity.
Aluminum nipples.
