Shimano ST-R4020 Tiagra 2-speed STI bled with BR-RS405 flat mount calliper
Upgrade your bike with the Shimano Tiagra ST-R4020 hydraulic disc brake and shift lever, designed for cyclists who want smooth, precise shifting and dependable braking. The slim, ergonomic dual control lever delivers intuitive gear changes with a short, natural shift arc, while the hydraulic system provides powerful, consistent stopping with minimal effort, especially from the hood position.
