Shimano Ultegra Di2 R8170 2 Spd Road Shift/Brake Lever

Road riding has never been this much fun. That's because the redesigned ULTEGRA ST-R8170 DUAL CONTROL LEVERS have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner.

Shimano's new ULTEGRA ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO WAVE technology. The all-new Di2 platform, used on both DURA-ACE and ULTEGRA, untethers the shifters while delivering our fastest, most reliable wireless shifting.
