Fulcrum Racing Zero Goes Carbon with new 30mm Tubular or Clincher Rim
Fulcrum’s flagship wheel is getting an upgrade. What can you do to improve a wheel that is already loved by so many? The obvious answer is carbon. Always more carbon. To bring the Racing Zeros to the next level, Fulcrum is introducing a new 30mm carbon rim to the current hub and spoke assembly. The result is a light weight set of tubular or clincher wheels with typical Fulcrum durability and precision.

Offered in both clincher and tubular rims, the Racing Zero Carbons use a unidirectional carbon rim with 3k weave for the braking surface. According to Fulcrum the inside of the rim does not have any spoke holes, though it is not listed as tubeless compatible for the clincher model. To accomplish this, the aluminum nipples are placed inside the rim before the final carbon is applied in a construction process called MoMag. On the front wheel, 16 straight pull aero aluminum spokes are laced to the carbon/aluminum hub. Like previous Fulcrum wheels the hub shell is produced from carbon while the flanges are constructed from aluminum. Inside are Fulcrum’s USB ceramic bearings.
The rear sees a two-to-one lacing pattern with 14 drive straight pull aero aluminum spokes, and 7 non-drive. Rear wheels use the same carbon and aluminum hub construction and see a Plasma Electrolytic Oxidation treatment on the freehub body. Claimed weights for the sets are 1268g for tubular and 1358g for the clinchers.
