Dura-Ace ST-R9120 Hydraulic STI Lever & Disc Brake Caliper

We’ve seen quality, highly tested components in the Dura-Ace line that we can’t get enough of, and Shimano’s ST-R9120 Hydraulic STI Lever & Disc Brake caliper has it all. Featuring an improved design with the rider in mind for comfortable hand placement, and a redesigned internal shifting unit that improves shifting performance and shortens your lever stroke, making this an optimal upgrade.


The ST-R9120 lever is similar to the 9170 in profile with its slim silhouette and refined grip. For the 9120, this super-light shifting operation makes for a comfortable grip with an adjustment range of 10.9mm reach. This improvement benefits the rider, and you’ll see a more customizable and precise lever position with added control. Quick and intuitive shifting comes with this model thanks to a shortened lever stroke that accompanies the redesigned internal shifting unit. And, hydraulic brakes will only help you with easy brake control for consistent braking performance in all weather conditions, so you don’t have to worry when those afternoon showers hit.



Flat mount brake calipers are a benefit to most road bikes and are becoming increasingly more popular due to the drop in grams we’re seeing in these lightweight models, and you’ll see them more on newer cross-country, road and gravel framesets. These brake calipers reduce drag thanks to the reduced impact on aerodynamic performance, as opposed to to post mount calipers. The result is a drag-reducing machine.



Paired with the ST-R9120 Hydraulic STI Lever, these brake calipers are low-profile with a finish that aligns with the remainder of the Dura-Ace group. Super quiet resin pads work with Shimano’s Ice-Tech technology to deliver maximum braking power and reliability for racing and grueling rides. Shimano uses mineral oil as fluid, which is a benefit thanks to the fact that it is safer for the environment, and it won’t harm your frame’s finish.
