Riding a road bike 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 brake modulation and wireless, electronic shifting function. Thanks to these three improvements, road cyclists can now concentrate fully 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 all-new Di2 platform is used on DURA-ACE and ULTEGRA for 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.
Battery life: 1.5 to 2 years with easily replaceable CR1632 batteries in the shift/brake levers (included)
SERVO WAVE technology for optimum brake control
