Shimano Ultegra Di2 ST-R8170/BR-R8170 Brake Lever/Caliper

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. The Ultegra ST-R8170 2x12 speed Dual Control levers with Wireless Di2 connectivity deliver a clean aesthetic and simple setup while reimagined ergonomics bring a new level of comfort and control. Ultegra BR-R8170 hydraulic calipers are the most compact yet. Mono-body construction ensures light weight and rigidity, proving that good things can come in small packages.
