SRAM X-Sync Steel Direct Mount Chainring - SRAM Direct Mount - 3mm Boost - Round - Grey - 30T Virtual Parent The BBT-49Genuine, 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.
