Chorus Aero Seatpost - Saddle Angle

I didnt find any similar query using the search. Bear with me, I dont find this the easiest thing to explain.

Ive got what i believe to be a Campy Chorus Aero seatpost - this one. I havent seen many Campagnolo seatposts with this sort of recessed bolt, but im no expert.

I have an old Flite on this post. When tightening the bolt, you have to sort of slot your Allen key into that recess there that runs vertically along the seatpost. This means theres not a lot of room to adjust saddle angle; it can be done, but if your looking for anything more than horizontal, the angle at which you have to introduce the Allen becomes almost impossible.

Putting the saddle at the angle I want makes the bolt more or less inaccessible, and as I tighten, it brings the saddle back down to horizontal as it catches.

This wrecking my head, as I like a little more support in the grundle area.
Ill try throwing up some pics of my own particular clusterfuck tomorrow.

My guess would be that you're using an allen key set?

Try with an individual key.

I know what you mean. Get one of those long park tools Allen keys (or another brand) with the ball end to get it almost tight, then a standard Allen key for final tightening.

Initially i tried with a set, then tried in my LBS today with a single key. It gave me a bit more traction, but the problem remains.

This could work... will give it a shot if i can get my hands on one of those. Nice one.

I use a ball end (oo er) allen key type on my Campag aero seatpost, it works fine at the angle I have.
