Seat post slightly too big,freeze it ?!
« on: July 23, 2014, 06:44 PM »
I have a seat post I am trying to get into my Decoster but for some reason it seems a very tight fit.
I know it's oldschool size as it came out of a Puch I split ages ago.
It also won't fit a Haro FST I have.
I have seen on here about freezing BB cups so they go in easier so will it work with a seat post ?

Sounds like it's either the wrong size or it's coated in powder.

Are you sure its not a section of scaffolding or lamp post as that won't fit?

Someone's out for mischief today...





Are you sure it's not a 22.6 when you need a 22.2mm?

This thread reminds me of the recent haro one where to get it in, the thing needed filing - but it's a really good way to bond the two together and potentially fook things up big time

The post came out of an oldschool Puch frame so I presumed it was 22.2 size,maybe not,learn something new every day.
Will see if it has shrunk tomorrow night....

If it's a very tight fit there is a risk that you won't get it out very easily when you need to; you would be surprised how much heat is generated forcing the two metals together and they could fuse together.  I would get a set of digital vernier calipers and check the inside diameter of the seat post tube and the outside diameter of the seat post before trying to force anything.


Better to crash and burn than fade away
