Shimano Dura Ace R9270 Disc Di2 Växelreglage

The Shimano Dura Ace ST-R9270 Disc Di2 shifters + BR-R9270 brake calipers is the perfect combination for extremely fast and precise shifting and the best braking power and dosage possible. The ergonomics of the Shimano Dura Ace R9270 shifters have been further optimised thanks to feedback from riders on various professional cycling teams.

The shifter covers have been improved in terms of grip and it is easier to place your fingers under the shifter. It is also easier to adopt different hand positions. The stroke of the brake levers is adjustable. The difference in height of the DI2 shift up and down buttons has also been increased by 1.5 mm. This makes it easier to operate the buttons correctly even with gloves or a cold.

Servowave
The brakes use Shimano's Servo Wave Action. This technology means that the speed at which the pistons go in decreases as the pistons get closer to the disc. This maintains the torque Shimano brakes are known for, but greatly improves the brake delivery.

Brake maintenance
Maintenance of the brakes is simplified. It is possible to bleed the brake without removing the caliper from the frame, thanks to a separate bleeding port and rotary valve. A new funnel and spacer for bleeding the caliper help optimise the bleeding process.
