The Shimano Tiagra RD-4700-GS rear derailleur represents the perfect balance between pro-level performance and accessible reliability. Designed for 10-speed road drivetrains, this medium cage (GS) model offers consistent, smooth, and light shifting action, inherited from Dura-Ace series technologies. With its architecture specific to the Tiagra 4700 group, it is the ideal choice for demanding cyclists seeking a low-maintenance drivetrain without compromising on precision.

Technical Architecture and Innovations

• Revised cable path: ensures increased shifting precision and durable performance over time, with minimal adjustments required
• Wide link design: the wide link construction significantly increases structural rigidity for more precise and firmer gear changes
• Optimized 11-tooth pulleys: reduce pulley wear and chain noise while improving rotation smoothness
• Two fluor bushings: ensure minimal friction at pivot points for maximum longevity and silent operation

Compatibility and Capacities

This medium cage (GS) derailleur accepts cassettes from 11 to 34 teeth in double chainring configuration (11-32 teeth in triple chainring). Its total capacity of 39 teeth allows accommodation of a wide range of drivetrain configurations. Warning: due to its specific cable pull ratio, the RD-4700-GS is exclusively compatible with Shimano Tiagra 4700/4703 and GRX 400 components – it does not work with other generation groups.

Construction and Materials

• Aluminum body: ensures lightness and resistance to mechanical stress
• Steel structural elements: guarantee durability in high-stress areas
• Contained weight: approximately 275-277 grams depending on measurements
• Compatible chain: HG-X 10-speed directional, with outer face optimized for front shifting and inner face for rear
• Integrated cable adjuster: facilitates precision adjustments on the road
