The Shimano ST-R9250-L Dual Control Lever brings top-tier Di2 precision to rim brake setups, delivering a wired, 12-speed interface tailored for competitive road cyclists. This left-side lever integrates seamlessly with Shimano’s R9200 series, offering crisp front shifting and refined braking control. Its carbon fiber lever and composite body trim weight without sacrificing strength, making it a standout upgrade for riders seeking the lightest and most responsive cockpit feel.

Designed for mechanical rim brakes, this lever employs Shimano’s Super SLR short-pull actuation, ensuring smooth modulation and confident stopping power. The hood shape and textured surface enhance grip, even in wet conditions, while the ergonomic lever profile provides a tactile, clearly defined click with every shift. Two SD300 ports allow flexible wiring options—either daisy-chained between levers or routed through a junction box to the BT-DN300 battery—keeping your cockpit clean and efficient.

The ST-R9250-L also supports satellite shifters via an additional SD300 port, offering customizable control for sprinting or climbing positions. With reach adjustability up to 16.4 mm, it accommodates a range of hand sizes and preferences. Firmware updates and shift customization are handled through Shimano’s E-Tube Project app, enabling riders to fine-tune performance to match their riding style.
