The longer, positive-rake tooth shape on the 3 mm SRAM X-SYNC 2 Eagle Cold-Forged Direct Mount chainring increases chain retention and pedaling efficiency while decreasing friction, noise and wear.

The longer, positive-rake tooth shape on the 6 mm SRAM X-SYNC 2 Eagle Cold-Forged Direct Mount chainring increases chain retention and pedaling efficiency while decreasing friction, noise and wear.

Used with an Eagle chain, the radical tooth profile on the SRAM X-Sync 2 Eagle Direct Mount chainring increases chain retention and pedaling efficiency while decreasing friction, noise and wear.

Based on intense study of chain and chainring wear patterns, the black and gold SRAM X-SYNC 2 Direct Mount chainring's radical tooth profile lasts longer, runs quieter and improves chain retention.

Based on intense study of chain and chainring wear patterns, the Polar Grey SRAM X-SYNC 2 Direct Mount chainring's radical tooth profile lasts longer, runs quieter and improves chain retention.

Based on intense study of chain and chainring wear patterns, the SRAM X-SYNC 2 Direct Mount Oval chainring's radical tooth profile lasts longer, runs quieter and improves chain retention.

Designed for peak performance and durability even in muddy conditions, the SRAM X-SYNC Direct Mount chainring features taller all-terrain teeth, exceptional retention and mud-clearing recesses.
