SRAM X01 Eagle Rear Derailleur

Yes, the X01 Eagle rear derailleur is fully compatible with both 10-50T and 10-52T SRAM Eagle cassettes.

The IP69K rating means this derailleur is completely sealed against dust and can withstand high-pressure, high-temperature water jets. In practical terms, it is exceptionally durable and will hold up well to aggressive trail riding, mud, and frequent washings.

This derailleur is designed specifically for the SRAM Eagle 12-speed ecosystem. While it may physically mount to other systems, it is optimized for SRAM's pull ratio and shifting geometry, so it is best used with a complete SRAM Eagle drivetrain.

The updated cage design is engineered to hold the chain more securely under high tension. This reduces chain slap and prevents dropped chains, providing a more stable and quiet ride, especially on rough, technical terrain.

While it is robust enough for the demands of enduro and trail riding, its lightweight construction makes it a popular choice for cross-country racers who want a reliable, high-performance component that doesn't add unnecessary weight.
