The junction between the seat tube and seat stay seems to be wider than SL8 for Aero (it gives me a BMC R01 and Benge feeling).
BCG will probably be more expensive, and it seems like they've reduced it by a few grams and increased it by a few watts~ It seems like this is the case. Technological innovation has been the same up to SL8, so now I really don't know the difference. I wish Specialized would try various things like Factor One... Hmm... ㅠㅠ
To be honest, S5 was already so well-made that it only managed to reduce 1@@g in the new model and the wattage difference was only 9w. This is a problem that can be solved by lowering the posture by about 2 degrees.
What do you think? I think it's become too perfect like Giant TCR, so there's nothing left to change.
