X-DirectDisc are the brand-new single chainring MTB direct mount in AL7075-T6. They are compatible with the current SRAM T-Type 12s (SRAM XX and X0) groups and chains. These chainrings are available with an 8-hole or 3-hole interface with different offsets, ensuring perfect integration with your transmission. The high-quality aviation alloy ensures a longer life than the aluminum alloy used on other chainrings. The "AERO" design ensures structural stiffness and lightness at the same time. The X-DirectDisc single chainrings have synchronized teeth (Narrow/Wide), which don't need a chain guide. The innovative tooth processing makes them optimal even in extreme mud conditions. Chainring available in 30, 32, 34, 36 and 38 teeth
