I have a Specialized Allez I bought a few months ago. In my quest to get the fit right I need to tilt the nose of my saddle up a bit(it is almost level to possibly down sloping a bit). I have looked at this thing from 20 different angles and can not figure out how to tilt it up.

There are 2 bolts, one I have access to the head of from the bottom, but all this one does is tension the bracket for forward and aft movement. The other bolt, the head is hidden by the saddle itself. It has a knurled head on it, but when I grab it with some pliers, all it does is spin and does not allow the actual bolt to turn and I cant get access to the top of the bolt head to get an allen wrench on it. Anybody have any ideas? Do I need to completely remove the saddle from the seat post in order to adjust the angle?
