That’s a fair comparison, as the SuperSix I am looking at is NOT the Hi-mod version (so also lower grade carbon). However, the SuperSix DOES include decent wheels, whereas the BMC does not IMHO. Also, I would not want eTap. I want Shimano (just personal preference).
5700 euro’s is way better, but it is still 2000 euro’s above budget. I can spend a little more than 3500-3800 euro’s, but not 2000 more. That’s a different league for me, unfortunately.
