Wireless Dual Control Levers with Hydraulic Disc Braking

Overview

The Shimano Ultegra ST-R8170 Dual Control Levers bring pro-level performance to everyday riders. Featuring the new Di2 wireless platform, these levers deliver Shimano’s fastest and most reliable shifting yet, eliminating the need for shift wires and giving a clean, streamlined cockpit.

Enhanced Modulation with Servo Wave: Employing Shimano’s proven Servo Wave technology, the ST-R8170 levers provide improved modulation and control. This ensures quicker engagement, more responsive braking and precise feel on every descent or sprint, making braking more intuitive and efficient.

Smooth 2x12-Speed Shifting: With a 2x12-speed setup, the Ultegra ST-R8170 integrates seamlessly with Shimano’s latest drivetrains. The levers are ergonomically refined for comfort, giving riders effortless access to shifting and braking even during the longest rides.

Compact, Quiet and Powerful Braking: The BR-R8170 hydraulic disc brake calipers set a new benchmark for road braking. Despite their more compact design, they offer a quicker initial bite point and enhanced modulation. The calipers run quieter than ever, minimizing pad rub and ensuring smooth performance in all conditions.

Combining smaller caliper construction with Shimano’s refined bleed system, these brakes deliver both pro-level stopping power and everyday practicality.

Features
  • Clean Cockpit: Wireless connection enhances aerodynamics and simplifies maintenance for a clutter-free cockpit.

  • Enhanced Modulation: Expanded braking control area ensures precise modulation and responsive braking on every descent.
  • Versatile Compatibility: Supports wired and wireless connections, with ports for additional satellite shifters.
  • Long Battery Life: CR1632 batteries power the shifters for 1.5–2 years, ensuring reliability during long-term use.

Technologies

  • Reach Adjust: Customizes lever reach to fit different hand sizes and riding preferences for improved control.
  • Servowave Action: Provides fast initial pad contact followed by progressive power multiplication for enhanced braking control.
  • Ice Technologies: Multi-layer rotor and finned pad design reduce heat buildup, extend pad life, and minimize brake fade.
    Ice Technology Pad:     Resin or metal compounds with aluminum fin back plates improve cooling efficiency and consistency.
    Ice Technology Rotor: Clad stainless steel–aluminum–stainless steel rotors dissipate heat for quieter, more reliable braking.
  • One Way Bleeding: Simplifies hydraulic oil routing for easy air removal and clean, efficient maintenance.
