What, if anything, do you put on the threads of a 2 bolt Campy seatpost?

VeloBase.com - Component: Campagnolo 1044, Record

I have one of these, never a problem for decades...also have a Zeus clone on a bike and last night one of the bolts on that one came loose on a ride. Of course I didn't have a 10mm spanner with me, so I limped home with it rattling, stopping every so often to get it finger tight.

I think I put a little grease on the threads when I assembled the bike. Was that a mistake? Perhaps I just didn't have it quite tight enough, or got the clamp angle slightly wrong? Any other ideas? I'm not sure I'd want to put loctite on it, as it's nice to have it adjustable.

Hmmm. I never put anything on mine. Maybe I'm making a mistake.

Perhaps you just didn't have both torqued down quite enough.

A little grease shouldn't do any harm. Your bolts just weren't tight enough.

OK, thanks everyone. Probably it will never happen again, just thought I'd double check my assumptions. Yes, there is now a tool in the seat bag just in case.

Grease on the threads was correct, Loctite not.
Getting this type of seatpost adjusted to level and properly tight is a bit fiddly w/o the Campagnolo "dogleg" wrench designed for the purpose.
Even better are the new rotating head 10mm spanners now available. Used one to change saddles on my FG last season, something I do every decade or so, worked a treat.

+1 to all of this. I didn't know the funny wrench in the tool kit was for the seat and managed it with the ratchet box wrench. The set I have is a less expensive one with more slop, and honestly that seemed to help too.

I would/will use anti-seize. Not a lubricant but by the fact that it is a liquid, does provide some lubrication. Helps get to a higher torque too, so be careful.

You mean one like this?

I haven't tried one but it looks like it would be excellent. I do have the Campy offset one, but honestly I find it easier with a standard open end spanner. I just have to flip it after each engagement of the bolt head.

That's actually one of the options I had considered. If it loosens again I'll clean it up and do that.

Yes, grease is good. The Campy offset wrench designed for these posts is only marginally better than useless, in my experience. The best tool I've found is a 10mm flex-head ratchet, and the finer the ratchet, the better. It's still a fiddly job compared to single-bolt posts, but it does allow you to get the bolts adequately tight and once set, they stay put.
