This listing is for a brand new AbsoluteBlack inner chainring. It is black in colour and oval shaped with 39 teeth and sold as photographed. To be used, this will require an outer chainring of suitable size.
The image shows the compatible groupsets but broadly speaking it's the Shimano 11 speed ones from r7000, r8000 and r9100 including the Di2 iterations. Will also fit the older 9000 and 6800 crank arms.
Has never been bolted to a bike so perfect condition.
