Product Information

The Shimano 105 ST-R7120 Dual Control Lever offers impressive ergonomic updates derived from extensive hand shape studies, making it a comfortable and intuitive choice for road cyclists. This mechanical 12-speed lever seamlessly integrates shifting and hydraulic disc braking, providing reliable performance and excellent control in all conditions. The internal shifting mechanism borrows robust design elements from Shimano's mountain bike technology, ensuring smooth and precise gear changes.

With a focus on rider comfort and performance, the ST-R7120 features a revised hood shape and blade position, shortening the reach and improving leverage for both braking and shifting. Its adjustable reach mechanism allows for personalized setup, accommodating a wide range of hand sizes. Paired with BR-R7170 flat mount calipers, you get confident stopping power with reduced rotor rub thanks to wider pad clearance and easy maintenance from the one-way bleed system.
