Dura Ace ST-R9120 STI

The R9120 Dual Control Lever offers a shorter lever stroke, an expanded reach adjustment range for precise lever position, and lighter front shifting operation for quick and intuitive shifting (and braking) in all situations. Further improvements are its renewed hood cover material and its comfortable ergonomic shape with more grip. 

The ST-R9120 are compatible with hydraulic disc brakes, while the ST-R9100 are suitable for rim brakes. 

Dura Ace BR-R9170 Hydraulic Flat Mount Disc Brake Caliper

The all-new DURA-ACE hydraulic disc brake caliper was redesigned for the highest level of road performance. Utilizing a lightweight and minimalistic Flat Mount design, the R9170 caliper features stopping power ideally tuned for road applications. The new RT900 rotor offers even greater heat management capability than Shimano’s SM-RT99 industry-leading ICE TECHNOLOGIES FREEZA rotors, resulting in unparalleled braking performance and reliability in the most demanding conditions.
