Shimano Dura-Ace Di2 ST-R9180 TT / Triathlon Front Control Lever
The Shimano Dura-Ace Di2 ST-R9180 is the front control lever specifically designed for Time Trial and Triathlon bicycles, where aerodynamics, control, and shifting precision are essential. Thanks to the absence of traditional mechanical cables, it eliminates the routing complexities typical of time trial bikes, offering a clean and extremely efficient setup.
Paired with the electronic system SHIMANO Di2 with “plug and gap” technology, this lever guarantees a smooth, fast, and reliable shifting experience, combined with the safety of hydraulic disc brakes, even in the most extreme race conditions.
Advanced electronic shifting and total control
The Dual-Control ST-R9180 lever allows you to operate the derailleur directly from the brake lever, enabling shifting from multiple positions and even while braking. This ensures maximum efficiency and pedaling continuity, reducing distractions and improving overall performance.
Made from CFRP (carbon fiber reinforced plastic), the lever offers lightness, structural rigidity, and the ability to adjust the grip width, perfectly adapting to the rider’s style and morphology.
Shimano Synchro Shift Technology
Thanks to the SHIMANO SYNCHRONIZED SHIFT mode, only one button per lever is needed to automatically and intelligently manage the rear derailleur and front derailleur. The system autonomously decides which derailleur to operate, optimizing the gear ratio in every situation.
