SRAM XX1 Eagle X-Sync Direct Mount Chainring The SRAM X Sync Eagle direct mount chainrings are characterised by a much quieter running of the chain and better self-cleaning in muddy conditions compared to their 11-speed predecessors. With the proven alternating thick-thin tooth profile, which is matched to the XX1 and XO1 Eagle chains, the X-Sync chainrings keep the chain always securely in place. The chainrings are available with 30 to 38 teeth as well as with black or golden SRAM Eagle logos.
