absoluteBLACK 1x Oval Direct Mount Chainrings for SRAM are designed for SRAM cranks that have a 3-bolt direct mount interface and removable spider, and will only work with 12-speed Hyperglide+ chains. Direct mount chainrings provide significant weight savings over a standard spider and chainring combination. They are crafted from CNC machined 7075 aluminum, and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2 - 14.4%, with timing of 110.5 - 116.3 deg. after TDC (top dead center).
Note: These chainrings will only work with Shimano Hyperglide+ CN-M9100, 8100 & 7100 chains due to different thickness of the teeth.
