The SRAM X-Sync 2 chainring is known for exceptional chain retention, reliable shifting performance, quiet operation, low friction, effective mud-shedding, and long wear life. Now, it's available in a more wallet-friendly version made of steel. The X-Sync 2 Steel Direct Mount Chainring gives you the same performance as the aluminum version at a fraction of the cost. There is a weight penalty, yes, but this steel version is actually more durable than its aluminum counterpart. It fits SRAM direct-mount mountain cranksets and is compatible with Eagle 12-speed mountain drivetrains, as well as earlier SRAM 11-speed mountain drivetrains. This option has a 3mm offset, for Boost chainlines (12x148mm rear spacing).
