The Racing Zero wheels are pretty much the gold standard for high-level aluminum road bike wheels. They convince with a unmistakable character, an extreme riding precision and the ability to transmit energy almost lossless onto the asphalt. Race after race, Zero wheels have become a synonymous for quality, performance, reliability and victory!
A special triple milling makes it possible to reduce the weight of these rims as far as possible. Due to the low weight the acceleration will be further improved. The rim height amounts 30mm at the front and the rear wheel. Furthermore the internal rim width has grown to 19mm, allowing a up to date setup.
The front hub has been redesigned, it is now smaller and lighter. The smoothness is ensured by the famous USB™ ceramic bearings. The front carbon hub and oversize aluminum flange provides an innovative mix between torsional rigidity and agility. The cap and cone technology maintains the most efficient angle of contact between the bearings and bearing seat, ensuring smoothness and durability for many years.
The aluminum spokes have been precisely chosen to ensure optimal rigidity and a improved aerodynamics. Thanks to the light weight aluminum nipples the peripheral mass was further reduced.
The Anti-Rotation System™ is designed to make sure that spokes will never lose their initial tension and remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
2:1 Two-to-On™: Doubling the spokes in the critical zones avoids slackening of the spokes and loss of rim tension.
Rim dynamic balance: The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. It is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.
One Hub Fits All: Different adapters mean that the wheel is ready to fit the various axis standard on the market.
Plasma Freehub: The Plasma treatment makes the aluminium especially hard and resistant to surface abrasion and wear.
Oversized flange on the drive side: Provides greater torsional stiffness, increases reactivity at each change in rhythm of the pedal stroke.
