Effortless Maintenance
Say goodbye to complex maintenance routines. The Dura Ace Di2 ST-R9180 + BR-R9270 features Shimano's proven One Way Bleeding concept and the Easy Hose Joint System. These innovations simplify brake hose exchanges and ensure trouble-free maintenance, keeping you on the road and away from the workshop.

J-Kit for Easy Installation
With the J-Kit hose joint, installation and removal of the brake hose are a breeze. The integrated olive in the brake lever streamlines the process, making it hassle-free. Spend less time fiddling with your brakes and more time doing what you love - riding.

State-of-the-Art Technology
The electronic Shimano Dura Ace Di2 ST-9180 Dual Control lever is engineered for Time Trial and Triathlon handlebars. Its Synchro-Shift mode allows you to shift effortlessly with just one button on each shift/brake lever, controlling both the rear and front derailleur. The brake lever is also designed with reach adjustment for a tailored fit, ensuring maximum comfort during your rides.

Lightweight and High-Performance
The Dura Ace BR-R9270 disc brake caliper boasts a one-piece Mono-Body design that's incredibly light and stiff. Compact in size, this Flatmount brake delivers exceptional performance. A 10% increase in brake pad spacing reduces braking noise, providing a smoother, quieter ride. Plus, when paired with the RT-MT900 brake disc rotor (sold separately), you'll enjoy an incredibly quiet and efficient braking system.

Effortless Maintenance
Maintenance is a breeze with the hydraulic 2-piston brake caliper. It features Shimano's trusted One-Way-Bleeding system and a unique bleed nipple and opening screw arrangement. This design minimises the risk of hose slippage during maintenance and eliminates the need to dismantle the caliper from the frame for bleeding.
