Hi all,
I am considering one of these two beauties- the s works 2013 with ultegra di2 and the r5 2012 vwd with either ultegra (di2) or dura ace. Does anybody have any thoughts on the relative merits and differences of these two frames? I ride mostly for pleasure but love to climb and feel the need to treat myself. I am not sure how di2 would fit the r5 frame but as these are half price at the moment i am interested.
many thanks in advance
