I decided to retire my VB-168 frameset and rebuild my VB-177. My current fleet is already filled with aero bikes that I ultimately prefer, and I just found myself not really liking the 168 even for what it is.
Now having ridden the 168 and 177 back to back, I think the 177 might be the better value.
That's interesting. The descriptions on VB say both are "2021" frames, but only the 177 talks about carbon (T1000) and build tech (EPS & latex moulding). The 168 just says nothing. That would support the theory that the layup / build quality on the 177 is better.
I was assuming the 168 would be stiffer because of its shape, but you're saying the 177 is in fact stiffer and just rides better?
You're clearly a specialized fanboy, how did the 168 disappoint? I realize your Allez Sprint is not the geometry of an SL7, but it's fairly close. You're saying you could tell them apart?
Did you measure the weight difference between the 2 frames?
Can you fit 32mm on the 177?
