RCR Fabrication along with Black Cat Bikes have created some really nice chainrings for SRAM X series cranks. The chainrings fit the X series cranks splines for a nice fit and easy installation. They are made out of 7075 aluminum and available in 32T and 34T for $40. Check out their blog post for ordering information.
