Diskiniai stabdžiai galiniai Shimano ULTEGRA ST-R8170(R) + BR-R8170(R)

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. Your time on the bike is precious, let Shimano make it even better. To the delight of riders and mechanics alike, the new ULTEGRA BR-R8170 caliper delivers enhanced modulation, a quieter brake system, and an easier than ever bleed process. The ULTEGRA R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.
