Carbon bike rims - Racing Light XLR clincher


The Rim:
  • Low profile full carbon: extremely limited weight.
  • Very high lateral stiffness and reactivity values for 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.
  • Carbon 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.

Oversize flange
  • Oversized flange on the drive side gives greater torsional stiffness, increases reactivity at any change of the rhythm of the pedal stroke.

Aerodynamic profile in steel
  • Aero spokes (22 front, 24 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.
