Shimano Dura-Ace Di2 ISWR9160 electric time trial shifters

The Dura-Ace Di2 SW-R9160 Shimano (ref. ISWR9160) are electronic satellite shifters for triathlon and time trials, designed to control an 11- or 12-speed Shimano Di2 drivetrain from the aerodynamic handlebar extensions.

They attach to the ends of the handlebar extensions and allow you to change gears without leaving the aero position – a major advantage in time trials and triathlons where every second counts.

Operation and use

These shifters operate using a single-button system per control. In practice:

• one press = rear gear change (or front, depending on configuration)
• fully customisable configuration via Shimano E-Tube
• can be integrated with Synchronised Shift mode, where the system automatically manages the chainrings to optimise the gear ratio

They are designed for use with Di2 main shifters (ST-R9160, ST-R9180, etc.), but can also operate independently on a properly configured CLM cockpit.

Key benefits

These SW-R9160 shifters are designed for pure performance:

• Gear changes whilst in an aerodynamic position
• Very compact design on handlebar extensions
• Wide Di2 compatibility (11- and 12-speed depending on setup)
• Advanced customisation via E-Tube Project
• Immediate responsiveness of the electronic system

The minimalist, single-button design minimises errors and facilitates quick actions during maximum effort.

Compatibility

The SW-R9160 is compatible with:

• Shimano Dura-Ace Di2 (11- and 12-speed)
• Shimano Ultegra Di2 (depending on generation)
• Triathlon/time trial handlebars with aerobars
• Shimano E-Tube systems (Di2 cabling)

They connect via the Di2 network and can be integrated into various set-ups, with or without main brake/shift levers depending on the configuration.
