Fulcrum Racing Zero Clincher Wheelset

The 2013 Racing Zero is the top wheelset of the Fulcrum aluminium range. Its extraordinary performance features and high impact aesthetics make it stand out from the crowd. Also new, is the mega-drive hub flange and a great new graphics makeover. Features:

• Racing Zero wheels are compatible with Campagnolo®, Shimano Inc. and Sram Co. drivetrains and are supplied with the new Fulcrum® quick releases
• Lightened/Milled rim
• Front/rear differentiated rim profile
• USB ceramic bearings: Lower friction, lower power loss, longer service life, corrosion-proof, simple fast maintenance
• Lightened aluminium spokes and nipples
• Dynamic balancing: Greater stability at high speeds
• Aluminum/Carbon hubs
• Oversize hubs: Light and stiff
• 2:1 Two to One spoke ratio: More effective transmission of the drive torque and appropriate distribution of the stresses
• Rim: Aluminium - 28"
• Hubs: Carbon/Aluminum
• Quick release: Dual pivot
• Nominal Weight: 1435gr

The rims are made of extremely high precision aluminium extrusions that make it possible to eliminate all the excess material, so they are ultra-light but at the same time very strong. The front and rear wheel profiles are differentiated: the 26 mm height for the front guarantees excellent aerodynamic penetration, while the 30 mm of the rear wheel means extremely effective transmission of your pedalling power. Both rims feature the special Fulcrum lightening between the anchoring points of the spokes and the patented Dynamic BalanceTM system that guarantees the maximum stability of your bike even at high speeds. The hubs have a carbon fibre body and aluminium flange; the special bearings combined with a larger number of balls compared to the standard version place the Zero at the top in terms of smoothness and service life. But we wanted more, so we decided to substitute the high quality steel ball bearings with the ceramic USB (Ultra Smooth Bearing) specially developed by Fulcrum®. This solution significantly increases the smoothness of the wheels, reduces servicing needs, and further decreases the weight. The spokes are aluminium aero spokes arranged in a radial pattern on the front wheel for better aerodynamic penetration and in the Fulcrum® 2:1 pattern on the rear wheel for immediate transmission of pedal stroke with no dissipation of energy. The nipples are also aluminium, further reducing the peripheral mass of the wheels and thereby increasing their performance.
