While the Record/Super Record two bolt seat posts are finicky, they are not impossible.

Sometimes the special Campagnolo wrench for this works well, other times it will get in the way.

I set the front bolt to get the best guess at saddle tilt first, then work the aft bolt to secure as the bolts should balance themselves. I always test the forward bolt later for insurance. I have seen saddles fall off bikes before, with the rider/mechanic in training looking for clamp parts along the road. A bit of grease at the pivoting parts helps a might.

I slide the fore/aft placement when under some tension.

Be sure that the lower side clamps are facing the correct direction, the relieved inner track faces forward 99.5% of the time for the best assembly. For the upper clamps, the bridge with the wider "slots" is forward. All this assumes you are not using the rare special narrow clamps for the Brooks narrow rail saddle.

The type of saddle you are using will make a difference as to how much trouble it all is, fortunately once done it does not get much attention after that.

Leave the simpler designs for the guys who need Simplex or 3ttt.
