The bulge on the seat tube is the butting, it is on the top 5cm.

Good luck with the PlusGas. It works way better than WD40, don't be tempted to scrimp!

Definitely looks like a 1992 Bolinas (my first marin and the bike that started the addiction)

Not too important but, that seat post isn't original.

The factory one was a cheapo 2 piece jobby, bmx style if you get my drift where you need 2 spanners to adjust.

Maybe somebody forced a larger one in.....as I say, the seat post is a super rare size that isn't shared on any other marin. To get a micro adjust version would be near impossible, reinforcing my theory of a misfitted seat post.

Cheers.

Don't hacksaw nowt, set fire to nowt, until you try that ^


And she's out!
Got the same freeze spray from Screwfix and on second try i actually heard it crack as the bond broke - amazing stuff, then cleaned up the post and can still see the size -26.6 and a good fit now cleaned.
Post isn't worth saving sadly - but won't be fazed by stuck seatposts anymore!
Got a nice old deore dx chainset to replace the biopace jobby as thats had it, and on with the build now....
Thanks again kind sirs!
Any one got a 26.6 seatpost? lol...

A hard size to get a decent post. I'd be tempted by a USE plus a shim if you want a trick post.
But may be a Thomson here...
