Shimano Ultegra Di2 ST-R8170/BR-R8170 Juego Frenos De Disco Trasero, negro (black)
ST-R8170
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 optimised ergonomics, even more precise brake dosing and wireless, electronic shifting function. Thanks to these three improvements, road cyclists can now fully concentrate on the next sprint, the next descent or the next joke from 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 fastest and most reliable wireless shifting. Time in the saddle is precious for every rider and thanks to SHIMANO it gets even better.
BR-R8170
To the great delight of riders and mechanics alike, the new ULTEGRA BR-R8170 caliper offers improved dosing, a quieter braking system and an extremely simple bleeding process.
The ULTEGRA R8170 disc brake caliper offers road cyclists a whole new sense of control thanks to its improved dosing and faster-gripping initial braking force. Despite the flatter design, the system produces less brake noise than ever before and is easier to maintain.
