Its odd that its got more setback, especially since setback is further exacerbated when the post is working to absorb the bumps and jolts. There again, Trek's seatpost Domane principle, as well as any flexible post (eg; Richey Flexlogic) also alters the angle when working as intended. But I'm not sure the reason behind Specialized putting more setback on this particular post unless it was a necessary approach to meet the vertical displacement number. Extra setback would not affect me since I run 9.8cm due to my leg and femur length. But I still don't like it being different from the others.
