Bora™ Ultra™ 80

SHARC

FEATURES & BENEFITS

• FULL CARBON HIGH PROFILE FOR 80MM TUBULAR: extremely limited weight. Gives the wheel an extremely high level of lateral stiffness and greater reactivity. 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.
• NEW BRAKE PADS MADE ESPECIALLY FOR CARBON WHEELS: the new blend increases the brake performance by about 40% on wet surfaces and 20% on dry surfaces without increasing the wear and tear on the pad. For a more modular and more secure stop.
• DYNAMIC BALANCING ON THE RIM: thanks to a special operation of the production process, the carbon fiber layup is positioned in such a way as to obtain perfect balancing of the rim even at high speeds.
• AERODYNAMIC PROFILE IN STEEL: ensuring the maximum aerodynamic penetration and, thanks to the material employed, lower weight and greater reactivity.
• SELF-LOCKING ALUMINIUM NIPPLES: it allows to maintain the right tension of the spokes and does not require any maintenance.
• CUP AND CONE BEARINGS: easy ball/bearing adjustment - reduces possible ball/bearing play - precision operation - maintains performance over time.
• CARBON FIBRE HUB: provides a high degree of lateral stiffness and reduces weight to the minimum.
• OVERSIZED FLANGE ON THE DRIVE SIDE: increases the torsional stiffness, increasing reactivity at each change in rhythm of the pedal stroke
• ALUMINIUM AXLE: reduces the weight of the wheel.
• QUICK RELEASE: new, completely redesigned and lighter aerodynamic-profile wheel block. Steel spine and eccentric, lever with drill lightening and aluminum die.
  Eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure.
