Hi,

This is a 26 tooth absoluteBLACK oval narrow/wide chainring.

It is a 64mm BCD fitting so is designed to go on the inside tabs of a 2x or 3x crankset with 110mm BCD outer tabs. From the info on the AbsoluteBlack website it gives a chainline of around 46mm.

More info here – https://absoluteblack.cc/oval-104bcd-chainring.html

It has only been on my bike for a couple of rides and will have done less than 50 miles with a new chain so has minimal wear.
