ShimanoGRXRxHydBrake&Shift-DropBarRt-llSpeed

Engineered for Gravel Performance
Shimano’s GRX RX600/RX400 system combines precision braking and shifting in a rugged design built for mixed-terrain adventures. Ideal for gravel racers and endurance cyclists seeking reliable road-gravel versatility, this integrated lever/caliper setup delivers race-ready control without compromising durability on rough roads.

Key Features
– Dual-Control Integration: Effortless 1:1 brake-to-shift ratio mirrors premium road systems, ensuring crisp gear changes and confident braking even in wet conditions.
– Gravel-Specific Ergonomics: Textured lever surfaces and optimized lever sweep accommodate gloved hands during long rides or technical descents.
– Customizable Fit: Micro-adjustable reach settings (15mm–25mm throw) adapt to hand sizes from XC riders to full-grip commuters.
– Low-Maintenance Hydraulics: Mineral oil fluid resists temperature fluctuations better than DOT-based systems, maintaining consistent performance across seasons.
