Elite road racers demand reliable and precise shifting, 12-speed Dura-Ace R9150 delivers with its super-lightweight and compact designSynchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur,The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur,The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load,The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts,The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead,Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available,12-speed E-tube SD300 wire compatible.

The new wider C17 rim design of the Zonda ensures a more efficient shape of the tyre, improving cornering grip and safety while reducing aerodynamic drag and rolling resistance. A seemingly small increase in width offers a surprisingly different riding experience, one that is sure to leave any cyclist convinced that a wider tyre size is the way forward. The differentiated rim height offers superior aerodynamics without sacrificing stability, the precision milling eliminates excess material reducing weight, the Rim Dynamic Balance Technology ensures that every point of the rim is counter-balanced by an equal weight on the opposing side, providing maximum stability even at high speeds and the MoMag Technology creates a tyre bed free of spoke holes, eliminating the need for rim tape and offering structural superiority. The front wheel is laced with 16 aerodynamic radial spokes and the rear is laced with 21 aerodynamic radial spokes in the MEGA G3 Pattern, creating the perfect balance of spoke tensions on both sides of the wheel, reducing stress, increasing transversal rigidity and improving the transmission of power to the wheel.
