Engineered for the passionate road cycling enthusiast, this component represents the perfect balance of pro-level performance and everyday functionality. As a core part of the revolutionary 12s Ultegra groupset, this right-hand lever brings SHIMANO´s most advanced wireless shifting and hydraulic braking technologies into a single, beautifully sculpted unit. Enjoy an uncluttered cockpit and the most intuitive riding experience available, whether you are climbing a mountain pass or sprinting for the line.
Unparalleled Wireless Shifting
At the heart of the ST-R8170-R is SHIMANO´s proprietary Di2 wireless shifting platform. This technology delivers lightning-fast, precise, and consistent gear changes with just a light touch of a button. By eliminating the physical shifter cable to the derailleur, you benefit from a cleaner aesthetic, simpler installation, and an incredibly responsive connection to your drivetrain. This lever is designed to flawlessly operate the 12s rear derailleur within the complete 2×12-speed Ultegra system, ensuring you are always in the perfect gear without a moment´s hesitation.
Refined Ergonomics for Superior Control
SHIMANO has meticulously redesigned the ergonomics of the Ultegra lever to provide unparalleled comfort and control on long rides. The taller, slightly curved hood shape offers a more secure and comfortable hand position, reducing fatigue and improving your grip and confidence when descending or navigating technical terrain. The updated button placement makes shifting more intuitive and distinct, minimizing the chance of mis-shifts, even when wearing thick gloves. The lever´s reach is also adjustable, allowing you to fine-tune the fit for your specific hand size and riding preference.
Advanced Braking Power & Modulation
Confidence in your brakes is paramount. The Ultegra R8170 lever incorporates SHIMANO´s proven SERVO WAVE ACTION technology. This innovative feature provides a shorter free stroke, meaning the brake pads engage with the rotor more quickly. Beyond this initial quick engagement, the power ramp-up is more gradual, offering superior modulation and finer control over your braking force. This results in smoother, more predictable stopping power in all conditions, from dry, fast descents to wet and winding roads. This combination of shifters and brakes gives you the ultimate command over your speed.
