Great speed means great responsibility. That’s why, faced with the task of making the new ULTEGRA groupset even faster, Shimano decided to take a holistic and 100% performance-focused approach. Shimano’s new 12-speed road groupset delivers unparalleled control and comfort anytime, anywhere – whether you’re competing in an amateur race, chasing your personal best, or out for a social ride. That is “Science of Speed”. And it’s what sets SHIMANO apart from the rest.

The completely redesigned ULTEGRA BR-R8170 brings new levels of control, optimised modulation and unmatched braking power to the road bike world. The new design minimises brake friction. In addition, despite its compact size, the new system is quieter and easier to maintain than ever before.
