  • Shimano Dura Ace Di2 ST-R9270 STI brake/shift lever

    In order to take account of the progress in professional sport, which not least also influences riding and grip positions, Shimano has worked closely with top athletes in the development of the current Dura Ace Dual Control levers. The result is lightweight controls that use the latest materials to provide an outstanding level of ergonomics, whether sprinting, on mountain stages or in time trials.


    UNIQUE ERGONOMICS. The ST-R9270 STI levers for hydraulic disc brakes are characterised accordingly by higher, slightly inwardly inclined horns. In addition, the clearance between the brake lever and the handlebar has been slightly increased for an optimal balance between comfort and control. The shift buttons have also been redesigned to be larger for easy access from the lower handlebar position, and better spaced to ensure intuitive operation even when riding with gloves.


    LIGHTNING-FAST SHIFTING. Another feature of the disc brake version is the Wireless functionality, which not only ensures a clean cockpit but also lightning-fast and precise shifting. Nevertheless, the shift/brake levers still offer a cable connection (EW-SD300) for the use of additional shifters in the drops or the top of the handlebar. For numerous customisation and configuration options, compatibility with the improved E-Tube Project app, which, like previous versions, allows you to adjust shift modes (Synchro-/Semi-Synchro-Shift, Multi-Shift), shift speed and button assignment on the fly.


    CONTROLLED BRAKING. But the Dura Ace R9200 Dual Control levers are also impressive in terms of braking performance. With the help of an extended brake control range, the Servowave technology ensures excellent dosing that offers optimum comfort and control even in challenging conditions. Of course, for individual adjustment, the levers feature the option of reach and free stroke adjustment.


    Shimano Dura Ace BR-R9270 disc brake caliper

    Its one-piece Mono-Body design not only makes the Shimano Dura Ace BR-R9270 brake caliper incredibly light, but also gives it outstanding stiffness values. At the same time, the Flatmount brake made from a single, cold-forged aluminium block proves that high performance is also possible with compact dimensions.

    A 10 % increase in brake pad spacing also allows for a significant reduction in noise during braking. In addition, when the RT-MT900 brake disc rotor (sold separately) is used, its deformation-resistant design, even with increasing heat, helps to create an extremely quiet and smooth braking system.

    To simplify maintenance, the hydraulic 2-piston brake caliper not only features the proven One-Way-Bleeding system, but also a separate arrangement of bleed nipple and opening screw. On the one hand, this minimises the risk of the bleed kit hose slipping off when opening or closing the system and, on the other hand, makes it unnecessary to dismantle the caliper from the frame for bleeding process.
