Good day all;

I very recently picked up a used TMR01 Ultegra 6800 from eBay. There is some question as to the year. Judging from the color scheme I want to say it's a 2013, but, the seller claimed he purchased it new within that last two years making it a 2015? It's not vital to know by any means because the bike is in great shape and I'm very happy. More of a curiosity.

Is there a way to decode the serial number?

TIA.
