Description
SHIMANO Dura Ace Di2 switching | ST-R9270 brake lever + BR-R9270 flat mount disc brake | individually
With the components of the 9200 Dura Ace series, Shimano also offers you the best that is currently available on the market. In every detail you can see the years of experience of the Japanese. Regardless of functionality, durability or weight, top values are achieved everywhere.
With this top group Shimano revolutionizes the Di2 components. From now on, the switching commands are passed on without cabling. The wireless technology with the transmission protocol developed exclusively for this guarantees you the fastest switching processes that have been possible in the bicycle sector up to now. A push of a button and the gears are quickly and reliably inserted. The precise pressure point of the lever ensures that the shifting processes are only triggered when the driver shifts consciously. Accidental operation is not to be feared.
In addition, the wireless chip scores with its low energy consumption. The lifespan of the CR1632 button cell is over 1.5 years. This system can be fully personalized with the Shimano E-Tube app. In addition, the switching logic is adapted to the preferences of the driver. Among other things, the switching speed can be set, a fully or semi-synchronous switching mode can be selected and the program buttons on the lever can be assigned specific functions.
When braking, you have optimal control over your bike at all times with the SERVO WAVE technology. This offers controllability and sufficient power that is second to none.
But not only the inner values convince. The ergonomics have also been significantly improved. The recessed grip is better formed and the rounded brake handles lie securely under your fingers even on long descents. In addition, the grip width is individually adjustable.
The lighter BR-R9270 caliper offers greater pad clearance and reduces noise levels. In addition, the peak of high braking performance has been reached with the brand new monoblock construction. Finally, a new venting technology makes maintenance easier than ever.
