Shimano Dura-Ace Di2 Electronic Shifting

The ST-R9270 right lever is part of Shimano’s top-tier Dura-Ace 12-speed Di2 platform, engineered for fast, accurate and consistent gear changes. Electronic shifting removes traditional mechanical cable stretch and contamination issues, giving riders reliable shift performance across racing, training and long-distance riding.

Wireless Cockpit Design

The lever transmits shift commands wirelessly, helping create a cleaner front end with fewer visible wires. This is especially valuable for modern aero road bikes and integrated cockpit builds where clean cable routing improves both appearance and aerodynamic efficiency.

Servo Wave Hydraulic Braking

Servo Wave technology changes how braking force builds through the lever stroke. The result is fast pad engagement followed by a broader modulation range, giving riders better control when braking hard, descending or riding in wet conditions.

BR-R9270 Front Hydraulic Disc Brake Caliper

The BR-R9270 front caliper uses Shimano’s compact mono-body construction, designed to reduce weight while maintaining stiffness. This improves brake response and helps create a consistent, confidence-inspiring lever feel.

Wider Pad Clearance

Shimano increased pad clearance by approximately 10% compared with the previous generation. This helps reduce rotor rub and brake noise, particularly after hard braking, wheel changes or long descents.

Carbon Lever and Titanium Hardware

The carbon fibre brake lever and titanium hardware help reduce weight while giving the component the refined feel expected from Shimano’s flagship Dura-Ace range.

Adjustable Ergonomics

Reach adjust and free stroke adjust allow riders to fine-tune lever position and brake feel. This is useful for different hand sizes, riding styles and handlebar setups.
