Shimano Ultegra R8170 Front Disc Brake Caliper

SHIMANO Ultegra R8170 Front Disc Brake Caliper

Elevate your road cycling experience with the SHIMANO Ultegra R8170 Front Disc Brake Caliper, a masterpiece of engineering that delivers unparalleled control and confidence on every ride. As a core component of the celebrated 12-speed Ultegra R8100 series, this caliper embodies the perfect synthesis of race-proven performance and everyday reliability. Designed for discerning cyclists who refuse to compromise, the BR-R8170 provides refined stopping power that allows you to brake later, corner harder, and descend with absolute certainty.

Experience a new standard in quiet operation. One of the standout advancements in this model is a 10% wider pad clearance compared to previous generations. This significant design improvement drastically reduces the chance of disc brake rotor rub, ensuring a quieter, drag-free ride so you can focus purely on your performance and the sounds of the road. The one-piece mono-body construction maximizes stiffness while minimizing weight, resulting in a firm, responsive feel and incredibly direct power transfer from the lever to the rotor.

Maintenance has been streamlined with a more user-friendly bleeding process. Thanks to a separated bleed port and screw, you can service your hydraulic system with greater ease and less mess, making it an ideal choice for both professional workshop mechanics and dedicated home mechanics. This self-service package contains everything you need for a front brake upgrade or build.

Key Benefits:

* Exceptional Control and Modulation: Enjoy finely-tuned braking power that inspires confidence, allowing for precise speed adjustments in fast-paced pelotons and on technical descents.
