The XX1 chain represents the latest breakthrough in a long line of precise, light-weight chains from SRAM. It's designed to deliver the greatest strength and reliability to a drivetrain that doesn't have to make compromises for front shifts since the XX1 system is a 1 x 11 system with a single front chainring.

The XX1 chainring features X-Sync™ which refers to a CNC-machined, wide tooth, narrow tooth pattern that is repeated around the entire XX1 chainring, perfectly mirroring the 1X11 XX1 specific chain's inner and outer links for maximum control.
