ST-R8170-R NEW

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.
