Rohloff has a decal, not engraved label on it. Not sure when they changed that but my 2013 has the engraved hub, not a decal. So, older than 2013.
Tires are Marathon XR from the photo. I do not recall how long ago the XR were taken out of production, but I recall reading of several long distance cyclists that wanted to stock up on them upon hearing that they were out of production. That might be close to a decade ago.
I bought one folding XR soon after that, put it in a plastic bag in storage and about a year ago when one of my (now discontinued) Hutchinson Globetrotters had a casing failure, put the XR on the front wheel of my Lynskey.
That bike on Ebay is in great shape. Looks like it was stored carefully indoors.
