SET ROTI FULCRUM RACING ZERO DB C19 2WF AFS 28" SHIMANO HG11 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._x000D_ The front hub has been redesigned, it is now smaller and lighter. The smoothness is ensured by the famous USBâ„¢ 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._x000D_ 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._x000D_ Further features of the Fulcrum Racing Zero DB wheelset_x000D_ The Anti-Rotation Systemâ„¢ 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._x000D_ 2:1 Two-to-Onâ„¢: Doubling the spokes in the critical zones avoids slackening of the spokes and loss of rim tension._x000D_ 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._x000D_ One Hub Fits All: Different adapters mean that the wheel is ready to fit the various axis standard on the market._x000D_ Plasma Freehub: The Plasma treatment makes the aluminium especially hard and resistant to surface abrasion and wear._x000D_ Oversized flange on the drive side: Provides greater torsional stiffness, increases reactivity at each change in rhythm of the pedal stroke._x000D_ Material: rims: aluminium 6082 T6 Pre-Aging_x000D_ spokes, nipples: aluminum_x000D_ hub FW: carbon with aluminum flange_x000D_ hub RW: aluminum_x000D_ bearings: ceramic_x000D_ Weight supplement: per set | manufacturer infromation 1590g_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
