Sram XX1 11 Speed Chain
The SRAM XX1 Chain 11-speed represents the latest breakthrough line of precise, light-weight chains from SRAM. It's guaranteed to deliver the greatest strength and reliability to a drivetrain. The XX1 chain has 4 times the 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.
