Shimano Tiagra FD-R4000 Front Derailleur - Down Swing | 2x11-speed - Braze-On (F)

Tiagra R4000 – Pure Road Riding

Authentic road cycling, enhanced with a wider gear range and more accessible than ever before. That is the 2x11-speed drivetrain system of Shimano’s redesigned Tiagra series. The mechanical shifting components are designed with a focus on practicality and user-friendliness. While the ergonomic and comfortable shift levers form the heart of the groupset, the CS-RS400 cassette provides the foundation for a lightweight road configuration that still offers a sufficiently wide transmission ratio to handle mixed terrain as well as steep climbs.
