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.

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 rims
• 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
• Weights:
• Front: 608g, Rear 868g Without skewers
• Front: 692g,  Rear: 934g With skewers

Please note - weight of the wheels is the actual weight of the wheels on our scales - not an average.

Maximum Compatibility:
With the new Fulcrum freehub body dedicated to non-Campagnolo drivetrains you will be able to exploit the maximum versatility of your current system. We have developed a freehub body that is perfectly compatible with Shimano Including 8, 9 and 10 speed systems and Sram 10 speed ones.
