Setting the bar for mechanical shifting.
Prepared to be wowed by Shimano’s sleek redesign of the Dura-Ace group, as the ST-9001 11-Speed STI shifters offers unmatched feel, lighter weight, and the smoothest mechanical shifting in Shimano’s long history.
Outfitted with Shimano’s Vivid Index Technology, the ST-9001 uses exclusive polymer-coated shifter cables, coupled with superior mechanics, to practically eliminate mechanical drag. The result is faster and lighter action, with downshifts feeling just as crisp, engaging, and as smooth as upshifts.
With ST-9001, Shimano advanced the shape of the levers and hoods by making them smaller and narrower than their predecessors. Shimano’s low-volume hood design (reminiscent of Di2) makes lever accessibility effortless, and they’ve also given the lever blades a more pronounced outward curve and included 10mm of reach adjustment, which improves contact whether you’re on the hoods or in the drops. Most importantly, Shimano has shortened the lever stroke by around 30% with the ST-9001, trimming shifting effort considerably (a claimed 47% for the rear derailleur and 43% for the front derailleur). It’s simple: the less distance the lever has to travel, the faster your shift will move up or down the cassette. It’s ingenious touches like this that show Shimano’s “Rider-Tuned” philosophy in action.

- Q & A
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?
Are these compatible with 6800 ultegra FD and brakes?
