Um, sounds like the post may be just a *hair* too small. The following
might help ...
1. new seat post bolt (I prefer the kind with Allen heads on each end)
2. new seat post
3. shim the post with a layer of rubbery electrical tape or (my
favorite) a piece of a Schlitz beer can.
Make sure that you don't deform the seat lug by cranking down on it too
hard. I've had these stretch for that reason and it ain't fun ...

| 748.2 | Shim it... | BTO::MAYOT | | Fri Jun 24 1988 14:12 | 8 |
| If the post is not sized correctly replace it with one of appropriate
diameter. A cheaper alternative is to shim it. You could take
a rectangular piece of flashing, about 1.5" by 3" and wrap it
around the post and insert it into the tube. I think I have
also seen an insert for this purpose in some bikes so maybe
there is an off the shelf product/part available.

| 748.3 | check if seat post nut rotates or if lug edges touch | VAXWRK::TCHEN | | Mon Jun 27 1988 12:10 | 8 |
| I have a Shogun 1500 with a similar problem. I noticed that when
I tighten the seat-post bolt with an allen wrench, the nut on the
opposite side rotates. This nut looks like it is held in place by
a split expansion ring. I have to see what to do about this.
If your problem is that the edges of the seat post lug are nearly
touching so that no further tightening is possible, then the insert
mentioned in .2 can be bought.

| 748.4 | Greasy seat-post? | RDGENG::MACFADYEN | Roderick MacFadyen | Mon Jun 27 1988 12:57 | 5 |
| Is the seat-post greasy? If it is, cleaning all the grease off with
spirit might help (don't know if this would be considered good practice
though, since most seat-posts seem to be greasy).

| I would worry about the post getting stuck if the grease were removed.

| 748.6 | Ah, the ol' beer can trick! | SCOMAN::DESHARNAIS | NO DUKES ! | Fri Jul 01 1988 12:23 | 14 |
| Thanks for the information.
The beer can shim trick mentioned in .1 worked. The seat hasn't
lowered at all for most of the week.
RE .3 Can you tell me what this insert is called and where it can
be bought?
RE .4 The seat post, as with many other parts of the bicycle, is
coated with grease to prevent it from rusting into the tube.
Regards,
Denis
