Ok guys in need of some help here.... Went to my LBS today to place the order for my 2013 TCR advanced SL 4, while looking at the inventory we realized there is a closeout on the 2011 TCR advanced SL 2 and would be roughly the same price. Looks to me that the major differences on this 2011 are the ISP, sram red components, and nicer DT Swiss wheelset. (also no internal cable routing on the 2011 which isnt a deal breaker for me) My question; has the frame changed enough since 2011 to justify sticking with the 2013? Which is the better deal here? Links below to both bikes, thanks a ton! 2011 tcr advanced sl 2 http://www.giant-bicycles.com/en-us/bikes/model/tcr.advanced.sl.2/7294/44032/#overview 2013 tcr advanced sl 4 http://www.giant-bicycles.com/en-us/bikes/model/tcr.advanced.sl.4/11488/55794/#overview
