Those seatstays better be pretty heavy and tough, or catastrophic failure of TT / seatstay junction in 3,2,1. They're much less deep than on the similar Madone - although this design obviously does without the stupid 90 degree TT / ST junction and gloryhole.
Presumably the top tube looping round the seatpost is *not* interference fit and has a rubber insert, allowing the seatpost to flex. If it's interference fit, how will the seatpost flex without cracking the TT loop? If it's not designed to flex, then what is the point of this design?
