Shimano Dura Ace 12 Speed RIM Brake Time Trial Di2 Groupset

 Shimano Dura-Ace Di2 Time Trial Disc Groupset – 12-Speed (Fully Wired)

A premium Shimano Di2 Time Trial groupset combining Dura-Ace R9100-series TT controls with Dura Ace R9200 12-speed drivetrain components.

Important: Unlike the current Ultegra/Dura-Ace road Di2 systems, this setup is not wireless. It is a fully wired Di2 configuration, purpose-built for time trial and triathlon use, and utilizes a combination of legacy SD50 wiring and current-generation SD300 wiring, linked via the appropriate Shimano converter. This ensures full Di2 functionality while maintaining compatibility with TT bar-end controls.
