Description Fulcrum's Racing Zero is the top wheel of the 2011 Fulcrum® aluminum line. Its extraordinary performance features and new stealthy aesthetic make a perfect addition to any race machine.
The rims are made of extremely high precision aluminum extrusions that make it possible to eliminate all the excess material, so they are ultra-light and 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 pedaling 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 fiber body and aluminum 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 Fulcrum wanted more, so they 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 aluminum 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 aluminum, further reducing the peripheral mass of the wheels and thereby increasing their performance.
Racing Zero wheels are compatible with Campagnolo®, Shimano Inc. and SRAM. drivetrains and are supplied with the new Fulcrum® quick releases.
Campagnolo: 1420g. per set; SRAM/Shimano 1465g. per set (weighed without quick release skewers).
