The Shimano DURA-ACE ST-R9270 is a 12-speed Di2 shift lever featuring a wireless connection for a clean cockpit and lightning-fast shifting. Engineered with pro rider feedback, the design includes a raised hood peak for improved ergonomics and a longer hood body for increased hand support. The lever is constructed with carbon fiber and titanium hardware, delivering a lighter and smoother action while reducing overall weight.

For braking performance, the ST-R9270 utilizes Servo-Wave technology to optimize hydraulic control and an expanded braking area for enhanced modulation. Powered by easy-to-change CR1632 batteries, the shifters offer 1.5 to 2 years of battery life and remain compatible with satellite shifters. Designed for use with mineral oil, this hydraulic lever represents the pinnacle of Shimano’s road drivetrain engineering.
