Shimano Dura-Ace Di2 ST-R9170 Shifter/Hydraulic Lever with Assembled BR-9170 Disc Brake Info
The Shimano Dura-Ace Di2 ST-R9170 Shifter/Hydraulic Lever with Assembled BR-9170 Disc Brake bundles Shimano's flagship hydraulic lever and flat mount disc caliper into a single purchase — so your brake and shift hardware arrives matched, bled, and ready to build around. The lever profile sits slim enough that it's barely distinguishable from a rim brake unit, while the integrated fluid reservoir and Di2 shift mechanism keep the cockpit clean and uncluttered.
Each kit includes the hydraulic hose and Shimano mineral oil brake fluid, meaning the hydraulic side of your build is complete out of the box. Available individually as a left or right unit — note that Di2 shift wiring and electrical components are sold separately and not included.
