The same stuff I use for my wheel bearings, etc. Actually ANY grease you have around will work for keeping the seatpost from sticking. The exception is a carbon seatpost in a metal frame where "carbon assembly paste" is a better choice.

I use white lithium for my aluminum and steel bikes and anti seize on my Ti bike. Never had an issue with a post getting stuck.

+1 Just remember to pull the post, clean and reapply the grease/assembly paste every few months or so.

Literally anything that says the work "grease" will work for this. You could probably use Crisco. Just use whatever you use for the rest of the bike.

Grease? I've never used any and never had a seatpost stick in the least. I'd worry about slipping more.

Whatever I have. I have a tube of Phil grease and a tub of some random automotive grease. I use whichever is at hand.

I use good old anti-seize, because that's what I want the post to do. Not seize.

But as everyone else has said, anything will work.

After retiring I admit I over PM my bikes but new grease or paste every few months would be excessive even for me.

Yes... Same that I use for bearings, same tub.

slipping with a 300# riser is different than slipping from a loose fit between post and frame..

You've been very lucky or you remove your seatpost frequently enough to avoid rather than prevent the problem. We get way too many threads here on how to remove horribly stuck seatposts to ever think it can't, and won't, happen. A properly fitting seatpost tightened securely will not slip even if greased thoroughly.

CRC SL3121 Marine Boat Trailer and 4 x 4 Wheel Bearing Grease. On Amazon. I have had to torch my seat post twice now. Must be something more common with vintage bikes like mine?

Anyways Marine Bearing Grease is waterproof and really cheap.

Agree. I built a bike in May of 2002 and greased inside the seat tube with high quality bearing grease. The saddle height was never adjusted for 12 years. I took the bike apart last summer for a new paint job and the post slid right out, still covered with a greasy film. Cleaned the inside of the tube with a long allthread wrapped with a rag. Guess what came out? Lots of clean grease.

Depends on post/frame material. For metal posts in metal frames I uses Phil Wood or any other good quality grease. For carbon posts or frames I use carbon assembly paste and also for aluminum into aluminum if the post is slipping. If the post is slipping I also break out the calipers since I've encountered some undersized seat posts.

+1. Not greasing the post & stem is nutso.

I've been riding bicycles for 50 years, never lubricated a seatpost or had one stick in the least.

I have had trouble tightening them enough to prevent slipping. I had a period when it slipped about 2mm/month. I broke the bolt trying to get it tight enough - keep it around as a souvenir. I solved that by cleaning the inside of the seat tube and the post thoroughly, consistent with grit or corrosion lubricating the surfaces.

Wouldn't an anti-seizing stuff serve this alleged purpose better?

Do you live in a desert? You clearly haven't worked on any old/used bikes. It's gotten to the point that whenever I go to look at a bike for sale I refuse to even consider buying it until I've loosened up the seatpost and stem to make sure they're not stuck. Most I've been able to remove. A couple have gotten the better of me.

It sounds like you're using a seat post that's too small. That's why you're having problems with it slipping (and broken bolts) and yet have never suffered a stuck post. A good fit has slight friction as the post is inserted into the frame. Grease delays the galvanic corrosion that occurs between the two parts.

Shoot, what's that? Less than an inch a year, I thought you might have suggested it was slipping 2mm a ride. I think I might have shrunk that much last year. Where can I find one?
