Road bike rims - Red Wind XLR 50

The Rim:
  • Integrated aluminium/carbon rim structure: the exclusive coupling system of the aluminium rim and carbon structure makes these road bike rims extremely rigid, it allows for excellent responsiveness levels and durability of the wheel.
  • Exclusive pressing system for the rim in unpainted carbon enables an extremely limited weight and a smooth surface free from imperfections.

Hubs and Flanges:
  • CULT™ ceramic bearings, the maximum in terms of smoothness thanks to the use of special reduced lubricant bearings.
  • The cone and cup technology with absolute performance: easy ball/bearing adjustment – reduces possible ball/bearing play – precision operation – maintains performance over time.
  • Aluminum hub body (gives the wheel a high degree of lateral stiffness and reduces weight to the minimum) 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.

Oversize Flange:
  • Increases the torsional stiffness, increasing reactivity at each change in rhythm of the pedal stroke.

Spokes and Nipples:
  • Aerodynamic profile in steel ensures the maximum aerodynamic penetration and, thanks to the material employed, lower weight and greater reactivity.
  • Self-locking oversize aluminium nipples: they reduce the peripheral mass of the road bike wheels to a minimum, thus increasing responsiveness.
  • The nipples' self-locking system gives the correct tension of the spokes and does not require any maintenance.
