absoluteBLACK Oval 104 BCD Chainring for Hyperglide+

• While designed for any cranks that use a 104 BCD mounting interface, this chainring only works with Shimano CN-M9100, 8100 and 7100 Hyperglide+ chains
• This is due to the different thickness and shape of the teeth needed for compatibility with these chains
• Oval shape helps reduce stress on knees without changing your ride feel; also helps maintain a better cadence while climbing
• Ovality has been optimized for each chainring size, ranging from 10.2 to 14.4%, with timing of 110.5 to 116.3° after top dead center (TDC)
• Crafted from CNC-machined 7075 aluminum with an anodized finish for excellent weight-to-strength ratio and exceptional durability
• 12-speed compatible
