48/31 chainrings. Approximately 2,300 miles on this. Happy to provide more pictures, but it’s in about the shape you’d expect - i.e. it looks fine but up close it has scratches and wear. Everything works.
Honestly no idea how much to ask for this. I have this on eBay for $350, but I gather that’s too much. New this would be $325 (Stages factory install) + $235 (MSRP for crank) = $560. Obviously this isn’t new, though.
What’s fair? $300? 
I’d rather sell it here for less than on eBay for more.
