Three years. That’s the approximate shelf life of a major-brand product in the bicycle industry. Whether it’s a carbon frame or an entire groupset, it has proven to be a consistent number. And that number has been overdue for the market leader, with Shimano finally unveiling its much-rumored Dura-Ace 9100 mechanical and Dura-Ace Di2 9150 groupsets.
While those expecting wireless 12-speed shifting are likely to be left wanting more, the new top-tier road groupsets showcase Shimano’s continued efforts towards greater efficiency and easier operation. Component integration, aerodynamics and ergonomics were also terms thrown around at the official product launch.
Much of the new groupset carries familiar features, but key standouts include Shimano’s first power meter, overhauled aerodynamic wheels, the first ever Dura-Ace hydraulic disc brakes, ANT+/Bluetooth connectivity, and a little automated shifting for Di2 users. All of that, plus a rather fancy black-to-silver fade aesthetic.
With it all being released at once, there’s plenty to tell. And remember, what starts at Shimano’s top-tier almost always trickles down shortly after.
