The Science of Speed. Speed was the mainspring in the development of this 12-speed road bike series of a new generation. Several years of research produced those innovations that make the Shimano Dura Ace R9200 even faster. Every component has been revised, refined and optimised to enable the decisive seconds of advantage – whether as a breakaway from the peloton or in the finish sprint on the Champs-Élysées.
The electronic Di2 parts rely on Wireless technology where it matters to make shifting even faster and more reliable. Smooth shifting is also the aim of the Hyperglide+ system, already known from the MTB segment, which is designed to bring out maximum performance and the full potential of every racer.
Additional, individual shifting options not only improve control, but can also make that decisive fraction of a second at the finish line.
The compact Dura Ace Di2 SW-RS801 remote shifter enables road bikes with Shimano 12-speed drivetrains to perform lightning-fast shifting operations, thanks to two different versions, either from the sprinter position in the drops (SW-RS801-S) or from the the top of handlebar (SW-RS801-T).
The connection to the E-Tube system is made via compatible STI brake/shift levers using the EW-SD300 cable (100 mm for SW-RS801-S / 260 mm for SW-RS801-T). The additional switch is attached directly to the handlebar using the integrated clamp (SW-RS801-T additionally fixed by cable tie).
