Freno de disco Shimano Ultegra 8170

The Shimano Ultegra 8170 Disc Brake is the hydraulic caliper from Shimano's flagship road groupset for riders who want performance that sits just a step below Dura-Ace. Designed for road disc brake systems, it delivers consistent, modulated stopping power in wet and dry conditions alike — the kind of reliability that matters on long descents and unpredictable group rides. Available individually as a front or rear caliper, it's built to integrate seamlessly into a full Ultegra Di2 12-speed setup.

Shimano's hydraulic disc technology is well-established on road bikes, and the 8170 caliper carries that lineage with a refined feel and precise lever feedback that gives you confidence through the braking zone. Whether you're running flat-mount on an endurance frame or building out a race-ready road disc build, this caliper is engineered to pair with Shimano's own levers and mineral oil hydraulic system for optimal performance.
