Canyon Aeroad model?

Hi all,

Doing a deal with an old friend to buy his hardly ever used Canyon Aeroad, but I just want to work out the model as he’s not fully sure. It’s Di2 ultegra and an upgraded Rotor front crank with upgraded Hunt Wheels.

I’m going to see it next week but just want an understanding of it beforehand! But I’m buying it regardless as it looks beautiful and I’ve wanted a Canyon for a long time now!

Any help would be great! Thanks
