Shimano GRX 11-Speed Rear Derailleur

** engineered for Gravel Precision & Road Reliability**

Tackle mixed-surface adventures with confidence using Shimano’s GRX 11-speed rear derailleur—a powerhouse built for gravel grinding and road endurance alike. Its Shadow RD+ clutch system offers adjustable tension control (0-3 clicks), silencing chain slap on technical descents while maintaining crisp shifts across loose gravel or paved roads.

Key Performance Enhancements
– Gravel-Tuned Shifting: Optimized clutch tension reduces derailleur bounce on uneven terrain without sacrificing speed
– Direct Mount Compatibility: Securely integrates with Shimano-compatible frames (10×1 standard spacing)
– 40T Chain Wrap Capacity: Smoothly handles 34T cogs for steep climbs while maintaining precise gear transitions
– Durable Construction: Black anodized finish resists abrasion from muddy rides; forged alloy components withstand harsh conditions
