Compatibility
- These rings fit any SRAM 76 BCD spider or Specialized Stout crankset. Here are instructions on how to measure your BCD.
- Threaded for standard M8 chainring bolts. For the XX1 spider, we recommend the 6mm bolts (or any short M8 chainring bolt). For the Stout crankset we recommend the 10mm bolts or the bolts that come with the crankset.
- If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention).
