SHIMANO Ultegra R8170 Front Disc Brake Caliper
Elevate your road cycling experience with the SHIMANO Ultegra R8170 Front Disc Brake Caliper, a pinnacle of braking performance and control engineered for the discerning cyclist. As a key component of the new 12-speed Ultegra series, this caliper brings top-tier technology into a sleek and refined package, ensuring you have the confidence to push your limits on demanding descents, in tight corners, and through unpredictable weather. This is the ultimate upgrade for any serious road or gravel bike equipped with a hydraulic disc brake system.
Unmatched Control and Quieter Performance
Experience a new level of braking modulation that allows for finer control and a more intuitive connection between your lever input and braking force. The Ultegra R8170 caliper has been completely redesigned to optimize your ride. One of the most significant improvements is a 10% wider pad clearance compared to the previous generation. This crucial enhancement significantly reduces the chance of annoying brake rotor rub, ensuring a quieter ride and less drag, so you can focus purely on your performance. The result is consistent, silent braking power you can rely on, mile after mile.
Superior Design and Simplified Maintenance
Crafted with a high-rigidity, one-piece MONO-BODY construction, the BR-R8170 caliper is both lightweight and incredibly stiff. This design minimizes flex under hard braking, translating every bit of hydraulic pressure directly into stopping power. The two-piston hydraulic system acts with pincer-like precision, delivering balanced and powerful force to the rotor for smooth, predictable deceleration. Maintenance has also been streamlined with a more user-friendly bleeding process. Shimano’s ONE WAY BLEEDING technology, combined with a separate bleed port and screw valve, makes purging air from the system quicker and cleaner than ever before, a feature appreciated by home mechanics and professional workshop technicians alike.
This front caliper is designed for the modern Flat Mount standard, integrating seamlessly with the clean aesthetics of today´s road bike frames. It comes equipped with Shimano´s high-performance L03A Resin pads, which feature ICE TECHNOLOGIES cooling fins to dissipate heat rapidly, preventing brake fade on long, challenging descents and maintaining consistent performance when you need it most.
