absoluteBLACK Oval Direct Mount Chainring - 30t SRAM 3-Bolt Direct Mount 3mm Offset Requires Hyperglide+ Chain Black. 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° after TDC (top dead center).

This chainring will only work with Shimano Hyperglide+ CN-M9100 8100 & 7100 chains due to different thickness of the teeth

Teeth have been 3D-machined for ultimate mud shedding and quieter operation

3mm offset converts any SRAM crank into Boost setup needed in Boost equipped bikes
