Complete Control with Hydraulic Precision

Description

The Shimano Tiagra ST-R4020/BR-RS405 brake set delivers a complete hydraulic braking and shifting solution for modern road bikes. Designed as a full assembled system, it ensures seamless integration and reliable performance right out of the box.

Refined Ergonomics for Better Comfort: The ST-R4020 dual control levers feature an updated shape inspired by Shimano 105, offering improved ergonomics for a wide range of hand sizes. The shorter reach distance enhances comfort and control, especially during long rides and varied terrain.

Smooth Shifting with Integrated Design: Combining shifting and braking into one unit, these levers provide intuitive gear changes with consistent braking feel. The 2x11-speed Tiagra system ensures precise and reliable shifting performance across all riding conditions.

Powerful Hydraulic Braking Performance: The BR-RS405 calipers deliver strong and consistent braking in all weather conditions. With hydraulic disc technology, you get better modulation and control, allowing confident braking on descents and technical sections.

Heat Management with Ice Technology: Compatible with Shimano Ice Technology pads and rotors, this system effectively dissipates heat during prolonged braking. This ensures stable braking performance and reduces fade, especially on long descents.

Low Profile Design with Easy Integration: The flat mount caliper design keeps the setup clean and compact while improving aerodynamics and frame integration. Pre-assembled J-Kit configuration with hoses simplifies installation and setup.

The Shimano Tiagra ST-R4020/BR-RS405 Hydraulic Disc Brake Set offers dependable braking, smooth shifting and rider-focused ergonomics in one complete package.
