BTW, on the seatpost issue, I own and race a 2014 variant of the Specialized Venge. It has an "aero" seatpost, with an odd clamp, and the saddle perch is secured to the seatpost with one bolt. Even though I am small, I had a few fights with that seatpost/saddle mount the first few months I had that bike. The bike shop finally got Specialized involved, and they replaced the clamp and replaced the cones that hold the saddle perch in place. That and carbon paste (each time the post or saddle is fiddled with) equaled "problem solved".
