Shimano Dura-Ace Di2 ST-R9180 TT / Triathlon Rear Control Lever
The Shimano Dura-Ace Di2 ST-R9180 rear is the control lever designed for Time Trial and Triathlon bikes, where integration, aerodynamics, and shifting precision are key factors. The absence of traditional mechanical cables eliminates the routing complexities typical of time trial bikes, enhancing aesthetic cleanliness and overall efficiency.
Thanks to integration with the SHIMANO Di2 electronic system and “plug and gap” technology, the ST-R9180 lever offers extremely smooth and reliable shifting, combined with the safety of hydraulic disc brakes, even at the high speeds typical of TT and Triathlon competitions.
Electronic Precision and Advanced Control
The rear Shimano Dura-Ace ST-R9180 lever ensures optimal power transfer thanks to a solid and ergonomic grip, designed to maximize control at every stage of the race. The shifting control is intuitive, allowing quick and precise shifts even under effort.
The integrated shift button, without manual release, further improves aerodynamics and safety, minimizing rider distractions.
Shimano Synchro Shift Technology and E-TUBE Project
The system is compatible with SHIMANO SYNCHRONIZED SHIFT: the single button on each side of the lever enables intelligent shift management, automatically optimizing the use of the rear derailleur and front derailleur.
Through E-TUBE PROJECT, all functions are customizable according to the rider’s pedaling style, including the option to enable or disable multiple shift function on all switches.
