First from John J., and followed up by Steven M., see my comments below it all: Date: Wed, 10 May 2006 11:41:32 -0700 From: John Jorgensen <designzero@earthlink.net> To: classicrendezvous@bikelist.org Subject: Re: [CR]Campy SR 2-bolt seatpost
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.

I find the 2-bolt seatposts quite easy to use and set up. John's description of how to best make it work corresponds very closely to mine. The sole thing that I would add is that I have a 10 mm wrench with a closed head with 12 indents (which doubles the chances of finding a perfect fit even if only tightening from behind between the rails.) Personally, I find it to be better than the purpose-built Campagnolo wrench. Using this wrench the Campagnolo design becomes simple, fast and permanent. I can't ask for anything more.

Steven says he couldn't ask for more, but indeed more is available. I got this idea here, from the CR list, quite some time ago.
Sears carries a ratcheting 10 & 9mm combo closed end wrench, for probably still under $10. They have it in a straight version, as well as an off-set version. I purchased both, thinking that the off-set wrench would be perfect for getting over the rear bolt and more easily accessing the front bolt, however this usually proves to be best done with the straight wrench. Simply keep your finger on top of the wrench wile in use, and it never slips. Some models have a little forward and reverse switch for each side. Others may simply be turned upside down, to change direction. Both the 10mm and 9mm sides are handy for a lot of brake caliper applications as well, so my pieces are kept in the "primary tool" drawer of my bike tool box, in my shop. Lotsa bang for the buck, and I no longer have to keep re-placing my wrench, anymore.
