Road cycling has never been so much fun. The reason for this is the new ULTEGRA ST-R8170 DUAL CONTROL shift/brake levers with their optimized ergonomics, even more precise modulation of the brakes, and the wireless electronic shifting function. Thanks to these three improvements, road cyclists can now fully focus on the next sprint, the next descent, or the next joke from a fellow rider. The new ULTEGRA ST-R8170 brake lever offers improved modulation and control on every ride, thanks to SHIMANO's proven SERVO WAVE technology. The brand new Di2 platform is used in DURA-ACE and ULTEGRA, where it enables the fastest and most reliable wireless shifting worldwide. Time in the saddle is valuable for every rider, and with SHIMANO, it becomes even better.
