SRAM X-Sync Steel Direct Mount Chainring - SRAM Direct Mount - 3mm Boost - Round - Grey - 28T Virtual Parent Made from stainless steelGenuine, budget replacement chainrings for SRAM direct mount compatible cranks. By making the chainring from steel, SRAM were able to bring the price of their X Sync technology down to a whole new level. As a bonus, these also last substantially longer than the alumium chainrings, they do weight a bit more though. Works great for 10 or 11 speed.
