• High Compatibility for SRAM Eagle Groups: Designed for XD driver body, compatible with SRAM Eagle 11/12-speed drivetrains (SX, NX, GX, XX1), perfectly matching mountain bike rear derailleurs and chains for smooth shifting.
• Multiple Cog Ratios for Versatile Riding: Available in 12-speed 9-50T, 10-50T, 10-52T and 11-speed 9-42T options, covering a wide gear range for steep climbs, fast descents and cross-country riding.
• Durable High-Strength Steel Construction: Made of high-tension steel plate with multi-layer electroplating for rust resistance, precision-cut teeth with anti-mud design ensure long-lasting performance and consistent engagement.
• Lightweight & Optimized Design: Optimized structure reduces weight (526g-547g for 12-speed, 419g for 11-speed) without sacrificing strength; reinforced large cogs improve durability under high torque loads.
• Precise Shifting & Easy Installation: CNC-machined teeth provide crisp, fast shifts; easy to install on XD driver hubs, no modification required. Note: For cogs larger than 42T, a derailleur extender is recommended.
