Overview
Shift/Brake Set Shimano Dura-Ace ST-R9270/BR-R9270 Di2 Left, 2-speed
The Shimano DURA-ACE Di2 ST-R9270 + BR-R9270 is a left-hand 2-speed electronic Dual Control shift and hydraulic disc brake set representing the pinnacle of Shimano road technology. Wireless Di2 connectivity ensures lightning-fast, ultra-precise front shifting while maintaining a clean, race-ready cockpit.
Refined with feedback from professional riders, the updated ergonomics, raised hood peak and extended lever body improve grip and control under maximum effort. SERVO WAVE technology enhances braking modulation and control range, while 10% wider pad clearance reduces rotor rub. A carbon brake lever, titanium hardware and one-piece construction maximize stiffness, reduce weight and deliver uncompromising race performance. With the E-TUBE app, shifting modes and button functions can be fully customized.
