The SRAM PC-X1 is an 11-speed chain built for 1x MTB drivetrains — designed with the geometry of SRAM's XX1 platform for dependable, lightweight performance across the full cassette range. Solid pin construction keeps the chain stiff laterally, and the 11-speed PowerLock master link makes installation and removal clean and tool-free.

Highlights

  • 11-speed chain for SRAM 1x MTB drivetrains (XX1, X01, X1, GX 1x11)
  • XX1-derived geometry for smooth, efficient chain engagement
  • Solid pin construction for lateral rigidity and resistance to stretch
  • Includes PowerLock master link — tool-free chain connection
  • Compatible with X-SYNC chainrings for clean chain retention

1x-optimised geometry

SRAM's 1x chain geometry accounts for the wider lateral angles a chain traverses when running a single chainring and wide-range cassette — from the smallest cog to the 42 or 50-tooth large end. The PC-X1's plate shape and pin profiles maintain efficient engagement across that full range without excess noise or drag.

Fit and compatibility

11-speed chain. Compatible with SRAM 11-speed 1x MTB drivetrains (XX1, X01, X1, GX 1x11). Pairs best with X-SYNC chainrings. Not compatible with 12-speed Eagle drivetrains — use an Eagle-specific chain for those. Replace before 0.5-0.75% chain wear.
