I'm looking to buy a Giant TCR 2016/2017 frameset, and through a 10-speed dura ace groupset I have in a box. A craigslist ad I was texting was explaining to me that the Advanced and Advanced Pro framesets are identical, but the "pro" frameset is the only one for sale because Giant thought it would seem better.

Is this true? I want the best TCR frameset without ISP, and hopefully get it for a bargain!
