The most refined yet.
If you thought Shimano's Dura-Ace ST-9000 shifters couldn't get any better, its ST-9001 11-Speed STI Shifters will take you by surprise. The 9000 series was a complete redesign from the 7900, with unparalleled feel, lighter weight, and crisper shifting, and the 9001 takes all of these one step further. The interface between you and your bike has never been more seamless.
While we are still excited about the ST-9001's 11-speed shifting option, we know that the extra gear no longer defines the tier. And while the original 9000 improved greatly upon touch-point experience, the 9001 series enhances the comfort, reach, and feel. Knowing that you spend 95% of your time in contact with the hoods or the levers, Shimano further refined the shape of the levers and the hoods. The hoods are smaller and narrower. Made from a dual-compound rubber composite, the low-volume hood design is reminiscent of Di2 and makes lever accessibility easy. The lever blades have also received a sleek redesign. Their outward curve and feel is more pronounced than in prior iterations, which makes for a more positive interaction from either the hoods or drops. And when you're buried in the drops on long descents, you'll be happy to know that Shimano included 10mm of reach adjustment for the levers.
Dwarfing all other advancements to the ST-9001, however, is the shifting itself — this is where Shimano's "Rider-Tuned" philosophy really makes itself known. This is the title given to Shimano's campaign of providing you the best rider experience of your life. Throughout the group, every component has been given little custom touches, but the levers have received several. To start, Shimano has shortened the lever stroke. In fact, it's reduced the stroke by around 30%. Obviously, the less distance that you have to push the lever, the faster your shift will move up or down the cassette. And during the act of shifting, the required effort has been lessened by around 47% for the rear derailleur and 43% for the front derailleur. In tandem with the reduced stroke, the shifting experience has been minimized to light touches that pit mechanical and Di2 shifting speed toe-to-toe against each other.Not surprisingly, the mad scientists at Shimano weren't satisfied with simply making the smoothest mechanical shifting in their history when they redesigned Dura-Ace. Instead, the bar was set even higher, and Shimano aimed to make the shifting effort seamless across every sprocket of the cassette. That's right, effort has been equalized, regardless of if you're moving across the bottom or moving across the top of the cassette. With Vivid Index Technology, down-shifting feels just as crisp, engaging, and as smooth as up-shifts. This is due in part to superior mechanics, but in the larger scheme of things, it's more attributable to something as simple as proprietary shift cables. ST-9001 uses Shimano's exclusive polymer-coated shifter cables. We know that it doesn't sound like a big deal, but the cables play a key role in the near-elimination of mechanical drag, and they also provide a flawless shift performance. The 9001 feature even lighter action than the 9000 series for faster, more effortless shifting.
The Shimano Dura-Ace ST-9001 11-Speed STI Shifters are available in one color and one size. Please note that these shifters are specifically designed for use with Dura-Ace 9000 and 9001 components and Shimano's polymer-coated and PTFE cables.

Are these compatible with 6800 ultegra FD and brakes?
DA9000 is the best
- Familiarity: I've put it through the wringer
Personally against everything else out there it is my favorite. It is crisp, smooth, reliable, I never have to worry about them it's a natural part of my bike.
Iterative, not new?
- Familiarity: I've used it once or twice and have initial impressions
Am I incorrect in understanding that the 9001 was simply a reactionary product to the failure of the 9000 shifters, where the shifters were shearing shifter cables very quickly?
