Re: [RBW] Seat Post Slippage

['Eric Norris' via RBW Owners Bunch]

FWIW, I have been advised in the past that, for standard (alloy, steel) frames 
and seat posts, you should never have to resort to anti-slip grease. 

A slipping post is a sign that something is mechanically wrong. In one case, 
the seat collar on one of my bikes had a small protrusion that was preventing 
it from gripping the post properly, leading to slipping. Once that was fixed (a 
few seconds with a file) everything worked properly.

The mechanics I trust have said that the proper course of action is to find the 
mechanical problem, not apply friction paste. The paste is a band-aid on the 
real problem, which will still be there.

I found the same on the Appaloosa frame I purchased a couple of years back 
- the 26.8 Kalloy post that came with the frame was a slightly loose fit in 
the seat tube with the binder bolt slackened off. I measured the post with 
my calipers, and it was accurately to size, so I bought a 27.0 Nitto S65 
post from Blue Lug, and used an expanding reamer in the seat tube until the 
27.0 post was a exact fit with no slop and no binding.

Re: [RBW] Seat Post Slippage

[Richard Rose]

This is fascinating. During a saddle swap I took a S83 post off my Clem & put a Kalloy in its place. No slip wig either. Then I got my Gus. Wanted to put the S83 on it. Absolutely could not get it to go in the Gus seat tube. Kalloy slid right in. Both are 26.8. Now I am suspicious the Kalloy might slip in the Gus once I get it on the trail.Sent from my iPhoneOn Jan 26, 2023, at 8:57 PM, Paul M  wrote:My recent Susie calls for a 26.8 seatpost but with the stock Kalloy seatpost there is a fair amount of play.

My recent Susie calls for a 26.8 seatpost but with the stock Kalloy 
seatpost there is a fair amount of play. I had a 27.0 Kalloy seatpost that 
fit snug and solved the problem. I'm not sure a Nitto 26.8 seatpost would 
have solved the problem for this frame.

Re: [RBW] Seat Post Slippage

[Garth]

I'll second the greasing the bolt head and threads. I had a recent 
experience with a Unior Truing stand whose uprights were out not parallel. 
They were adjusted using 2 bolted collars, not unlike Park stands. Neither 
had a lick of grease in the threads, and one wasn't even set. Loosening 
them, I heard that awful sound of metal on metal, so tightening them as 
they were wasn't happening without some lubricant. I applied some 
anti-seize compound on the threads, and then they were easily tightened 
like cutting butter. 

The brand of seatpost has nothing to do with it slipping in the frame, 
given it's the correct diameter. Do measure.

Re: [RBW] Seat Post Slippage

[Mike Packard]

I had this on my Atlantis, took it to my LBS (Cycleast) who used a cordless 
drill with a flex cylinder hone brush attachment for about 60 sec and never 
had another issue.

Re: [RBW] Seat Post Slippage

[Joe Bernard]

I'd go ahead with the Super Grip and crank down on the bolt a little more. 
The worse that happens is you snap the bolt and need a new one but that's 
not likely. If this doesn't work then you just got unlucky with the 
diameter on the post, I've run into this on a couple frames with it.

Re: [RBW] Seat Post Slippage

[lconley]

You need to lubricate the binder bolt because:
1. It can gall if not lubricated, especially if the bolt and nut are 
stainless steel.
2. The lubricant allows more of the force that you apply to go into 
tightening the bolt and clamping the post and less to overcoming friction.

If all else fails, you can knurl the seat post where it fits inside the 
upper inch or two of the seat tube. The fancy tools (Stein) make it easy, 
but a hammer, center punch and finesse & patience work also.

Re: [RBW] Seat Post Slippage

['Slacky Mac' via RBW Owners Bunch]

I did swap my stem out for a Nitto, but did not have issues with slippage 
for the few miles of shake-down use on my new Sam.  It also held the bike 
for it's build, but that is no real test.   I left the binding bolt stone 
dry as it is a nylock.  This is not an area where I wanted to over-torque 
and torque specs are generally fairly low for the post due to the surface 
area involved.  I use anti-seize on the post, and the frame has a ton of 
anti-corrosion goo, so it's pretty slippery in there.

Here is what my Sam Gap look like for comparisons.

Re: [RBW] Seat Post Slippage

Is there grease on the binder bolt threads. Is the head of the bolt greased
where it contacts the frame? If either answer is no, you just may not have
the binder bolt tight enough.

[RBW] Seat Post Slippage

[Drew Henson]

Anyone have any issues with the stock seat post (the one included with the 
frame) slipping with the latest sam frames? Happened to me on my first 
shakedown ride yesterday. 

I have a new nitto stem and some park tool supergrip on the way but was 
curious if anyone else experienced this. Or if there's any advice on using 
the park tool super grip?

Re: [RBW] Seat post slippage

[Jon BALER]

I once had a Steelwoold Tweed with a slightly oversized seat tube, and 
binder bolt wouldn't get tight enough to prevent vertical slipping.  A thin 
paper shim solved the problem.

Re: [RBW] Seat post slippage

[lconley]

I use a brake cylinder hone when I get a new frame to clean out the inside 
of the seat tube. Rivs are much better than 70's French frames, but it 
still doesn't hurt. Also prevents the frame from scratching up the seatpost.

Backing up what Eric said, I've had this issue on a couple MIT Rivs, including

benefit from an inspection and quick once-around with a round file.

Re: [RBW] Seat post slippage

['Eric Norris' via RBW Owners Bunch]

Carl:

I had a similar problem once. Take the post out and feel around the inside of 
the seat lug. You’ll be looking for a ridge or imperfection … and it looks like 
you may have one on the left side toward the rear, based on the scratches on 
the post. If you find anything like that, carefully file it down so it’s smooth 
all the way around.

A ridge or high spot like that will keep the lug from holding the post firmly 
all the way around, which can lead to slipping.

Good luck!
