SRAM XX1 Eagle chain features smooth-radius links with no sharp edges or chamfers — a design choice that reduces friction and noise as the chain engages with X-SYNC cog teeth. The result is one of the quietest, most efficient 12-speed chains available, running cleanly across the full 10-52 Eagle cassette span.

Highlights

• 12-speed Eagle chain at XX1 grade
• Smooth-radius link design — no sharp edges, reduced friction and chain noise
• Engineered for low noise and efficient power transfer across the full Eagle range
• Includes PowerLock master link for tool-free installation
• Compatible with all SRAM Eagle 12-speed drivetrains

Smooth radius links

Where lower-tier chains have chamfered plate edges to assist chain engagement, XX1 Eagle uses a smooth radius — the chain slides onto X-SYNC teeth cleanly without the micro-impacts chamfered edges can create. This reduces chain noise and friction at the point of engagement, contributing to the notably quiet running of high-end Eagle builds.

Fit and compatibility

12-speed Eagle chain. Compatible with all SRAM Eagle 12-speed drivetrains (XX1, X01, GX, NX Eagle). Replace before 0.5% chain wear to protect Eagle cassette and chainring longevity.
