Shimano Dura-Ace ST-R9270 Shift/Brake Lever Left 2-speed

The new lever ergonomics of the DURA-ACE ST-R9270 DUAL CONTROL shift/brake levers offer a new level of comfort and control for road cyclists. Thanks to Shimano's fastest wireless shifting performance and even more precise brake force regulation, the DURA-ACE sets new standards in performance.

Now equipped with SERVO WAVE braking technology, the DURA-ACE ST-R9270 brake lever offers a level of responsiveness and control that is second to none. Wireless shifting provides a clean look on the bike and enables uniquely fast and precise shifting. All this is integrated into a DUAL CONTROL shift/brake lever that is both lightweight and ergonomic thanks to the use of state-of-the-art materials and ensures optimum comfort and control even in challenging conditions.

SEROWAVE Action
The SERVOWAVE brake lever absorbs a lot of brake travel at the beginning of its movement, so that the pads can be guided to the brake disc with little lever travel. After the brake pad is in contact, the power transmission factor increases rapidly. The greater part of the lever travel is thus still available to increase the braking force and to dose it more precisely.

Reach Adjust
The brake lever is equipped with a reach adjustment. This allows the grip to adapt to the size of the rider's hand or to his riding style or personal preferences.

DUAL CONTROL LEVER
DCL stands for DUAL CONTROL LEVER. It has braking and shifting functions and enables easy operation.
The improved ergonomics are probably even more important for the high standard than additional gear ratios. The technology of the new shift levers brings the stability of SHIMANO's MTB technology and works so precisely and smoothly that it becomes possible to shift with just one finger at the front and rear. This is really a highlight of SHIMANO TOTAL INTEGRATION. To understand it, you simply have to experience it for yourself.
