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