Technologies

Dual Control Lever
DCL stands for DUAL CONTROL LEVER. The lever performs braking and shifting functions and is easy and intuitive to use.
Ergonomic innovation is fundamental to the higher standards of Dura-Ace performance compared to additional ratios. The new internal shifting mechanisms owe their robustness to our MTB technologies, and are so efficient that it is possible to change gears or chainrings at the touch of a finger.In fact, the shifting action represents the ultimate fulfilment of the SHIMANO TOTAL INTEGRATION philosophy, and only those who have experienced it can understand its advantages.

Lever travel adjustment
The brake lever is equipped with a mechanism for adjusting the travel. The distance between the handlebar grip and the lever can be adjusted to suit hands of any size and the rider's individual style and preferences.
