    Hydraulic flat mount disc brake consisting of ST-R9170 shift and brake lever + BR-R9120 hydraulic disc brake.

    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. 

    Dura Ace BR-R9170 Hydraulic Flat Mount Disc Brake Caliper

    The all-new DURA-ACE hydraulic disc brake calliper was redesigned for the highest level of road performance. Utilizing a lightweight and minimalistic Flat Mount design, the R9170 calliper 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.
