I have a Trek X-Caliber 8 with a SRAM SX Eagle 12 speed drive train, but I only have a SRAM NX Eagle chain. What is the exact difference between the two chains, and how can I modify my chain to make it work with my bike?

  • I do not have another Eagle chain
  • The chain is too long, not too short
  • I do have a chain breaker, but the pins seem to be stamped so you can't take them out? My chain breaker might just not be up to the task.

The NX chain is of slightly higher quality, so it will last longer and shift better. That's not relevant here though.

Yes, you need to shorten a new chain in most cases. The riveted pins increase the chain's strength, but do require a decent chain tool to punch out. Hold the new chain up beside the old chain, matching link to link, and break it at the same length/link count.
