All the best. All together.

When Shimano's Dura-Ace 9000 came onto the scene, we expected a few bits and pieces to be revamped. Not so with Shimano. Its engineers took an eraser to the drawing board and redesigned the complete component package. Every part is lighter and stronger, with an emphasis on aesthetics. Not to be overlooked, however, is the seamless integration of the components to achieve perfect symbiosis between your body and your bike.

Sure, the 11-speed shifting makes the Dura-Ace 9000 Groupset awesome, but it's not merely the addition of a cog that defines the success of the set. Starting with the shifters, the previous 7900 version slimmed down by 14 grams for the 9000 edition. And while weight savings is always impressive, the new design of the hoods, which improves on touch-point feel, is the real focal point. Comfort, feel, and reach have also been enhanced. The hoods were constructed of a dual compound rubber composite, and their new, lower volume makes the levers more accessible. Speaking of the levers, they have a more pronounced curve and feel than previous iterations, which makes for a more positive interaction with the hands from either the hoods or drop position. A 10mm reach adjustment in the levers will have your hands happy on long descents.

Although the redesign of the shifters is eye-catching, Shimano's "Rider-Tuned" philosophy is what is responsible for Dura-Ace 9000's rider-connecting experience. "Rider-Tuned" is the philosophy of providing added touches throughout the group, such as a shortened lever stroke. In fact, the lever stroke has been shortened by a full 30%. This shorter distance increases the speed at which your shift moves up or down the chainrings or cassette.

Moving down the drivetrain, the redesign of the front derailleur matches the new shorter stroke lever action of the shifters. To achieve this, Shimano had to revise the actuation ratio. This was done by giving the derailleur body a heightened profile, with the leverage point at the top of the body. The larger pull arm creates more leverage, which strengthens the pull, eases the actuation, and thus lessens the shift stroke. In a similar manner, the rear derailleur was redesigned to also change the leverage points. To this end, the cable bolt anchor rests at more of a forward angle than on the 7900. In the 9000 series, you'll see the return of the carbon cage, which not only reduces weight by 6 grams, but it also helps to reduce vibratory interference and produces light, crisp shifting over the cassette. The new 9000 shifting experience creates an equal, positive sensation regardless of the direction of shifting, unlike the more familiar Shimano "snap" moving up the cassette, and "drop" sensation on the way down. The combination of new levers and re-engineered derailleurs creates a reduction of 43% in shifting effort in the front and 47% in the rear. The groupset includes the CS-9000 11-speed cassette and Dura-Ace chain.

Tying the drivetrain together is the venerable Dura-Ace crankset, which, in the 9000 style, was completely redesigned. It features a revolutionary design that allows the use of either standard or compact chainrings on the same crankset. Voila. The first thing you will notice are the aesthetics. Gone is the 5-arm spider; it is replaced with a 4-arm that not only matches rigidity with the 7900, but it also shaved about 52 grams in the process. Like the 7900, it also uses Shimano's Hollowtech II construction. Hollowtech is a strategic placement of hollow aluminum throughout the crankset and chainrings, which allows more structural material to be used. When the FC-9000 is coupled with Shimano's BB-9000 bottom bracket, an unrivaled stiffness-to-weight ratio is created.

All the smooth gearing and shifting is for naught if you can't stop smoothly once you get rolling. The Shimano Dura-Ace 9000 brakeset receives accolades from riders who insist it's the best Shimano has ever made. Shimano began the design from the ground up. They used a dual-pivot design, so the mounting bolt is no longer also the pivot. As a result, the brake arms are now located symmetrically over the wheel and work independent of the mounting due to an integrated rolling cam. The cable stop is still to the side, but the new dual-pivot design allows any pull to apply equal tension to both arms. In addition, the arm placement is closer to the rim, which, coupled with the equal pull, drastically increases modulation. And if you run larger tires, Shimano is now producing a thinner brake pad for tires up to 28mm wide.

The Shimano Dura-Ace 9000 Groupset is available in three crank lengths: 170mm, 172.5mm, and 175mm, with either standard or compact chainrings. Each is available with either 11-25t or 11-28t rear cassettes.
