The SRAM CN-PCXX1 Chain 11-speed represents the latest breakthrough in a long line of precise, light-weight chains from SRAM. It's signed to deliver the greatest strength and reliability to a drivetrain that doesn't have to make compromises for front shifts. The XX1 chain has 4 times the elongation (wear) resistance to our 10-speed chains. This is due to the new finishing process on the inner links and rollers. Push pin strength, and ultimate strength are equivalent to our current chains. The XX1 chain lasts longer and is just as strong. (118 link)
