Disc Shimano Dura Ace Di2 BR-R9210
The flat-mount brake caliper for the new Dura Ace 12-speed 9200 series. Compatible with all Shimano hydraulic road bike disc brake levers.
The components of the pros: the high-end Dura Ace wireless 12-speed series, crafted from the finest materials – titanium, carbon and aluminium.
The new Dura Ace ST-R9270 Di2 Disc Dual Control shift and brake lever offers improved modulation and control thanks to Shimano’s proven Servo Wave technology. The brand-new Di2 platform is used in Dura Ace and Ultegra, where it ensures the world’s fastest and most reliable wireless shifting.
The new Di2 platform for Dura Ace 12-speed components requires no cable connection between the shift levers and the rear derailleur and front derailleurs. The Di2 Dual Control shift levers ST R9270 have the necessary wireless module integrated. Power is supplied by CR1632 batteries, which have a service life of up to 2 years. The Di2 12-speed rear derailleur, with its additional wireless unit, acts as a receiver and distributor of shift signals and is connected to the battery and front derailleur for power supply and shift command transmission. Additional wireless components, including those from third-party manufacturers, can also be paired with the rear derailleur. The shifting logic and speed of the shifting operations, semi-automatic or fully automatic shifting, etc., can be personalised using the E-Tube app.
Shimano Dua Ace Disc Brake Caliper BR-R9270:
The BR-R9270 road bike disc brake calipers for the 12-speed Dua Ace groupset. These calipers are compatible with all Shimano disc brake levers. Recommended brake discs: RT-MT900. Thanks to the 10 per cent greater spacing between the brake pads, the brakes can be adjusted more effectively and noise is minimised.
The new Dura-Ace BR-R9270 brake caliper offers improved modulation, a quieter braking system and an extremely simple bleeding procedure. The Dura Ace R9270 disc brake caliper offers road cyclists a completely new sense of control thanks to its improved modulation and faster-acting initial braking force. Despite its flatter design, the system produces less braking noise than ever before and is easier to maintain. The bleeding system has been redesigned and made significantly simpler.
Flat Mount Standard:
The new Flat Mount caliper standard for road bike brakes reduces weight and offers a significantly sleeker look. With the Flat Mount Standard, the rear brake caliper sits directly on the chainstay; no adapter is required for mounting the brake caliper. The bolts pass through the chainstay from below directly into the brake caliper. A flat adapter is still required on the fork. The adapter is screwed onto the rear of the fork leg, with the brake sitting directly on the adapter.
