Shimano's Di2 drivetrain continues its evolution and with the release of the Dura-Ace ST-R9170 Di2 Hydraulic STI Lever & Disc Brake Caliper, an entirely new hydraulic disc brake system comprising STI shift/brake levers and new flat-mount calipers. Previous versions of the top-tier Di2/Hydro levers and calipers were handled by the ST-R785 set, a model that wasn't confined to a group and most likely a place holder until the UCI decided its stance on road bike disc brake use in competition. This marks the first time we see hydraulic disc brakes under the Dura-Ace moniker and we couldn't be happier. Shimano's excellent E-Tube project offers customizable shifting set-up so no matter your cycling discipline, you are fully in control in how you program your shifting. Sold as individual right and left levers, the levers include specific BR-R9170 flat mount brake calipers and hydraulic hose kits.
