Seat post sizing

letmetalktomark · Jun 19, 2007

Hello,

Had some really good advice from you guys (and gals) so here goes again!

(Mark promises to repay countless favours......one day! One voucher per person!)

Quick question:

How much leeway do frames tend to have with regards to the size of seat posts?

My Kona originally came equipped with a 27.0 sized post but 27.2 seems more common now.

Does anyone know if a 27.2 should/would fit in a 27.0 sized hole?!

A fiend of mine had a Zaskar, and he changed the seatpost to a better looking Kore I had left.
Later I found the old Kore, I looked at the post and saw it was a 27.0
My Kore was a 27.2. They both fit in.
I heared my GT LTS should have a 27.0 and I always use 27.2

And.. I have a zaskar frame on the wall (yes that one <----) and I bought it as a 27.0 seattube, tried a 27.2 and it fits.
So answer will be a yes from me.

it depends on the frame itself some older frames could talk a 27.2 and some cant but 99.9% of the time you can get away with it if not DONT FORCE IT or it will f*** your frames seat tube then you have to take it to your lbs where i get to laugh at people that just dont lisen and try my best to remove it (lol this happend recently the young lad just wouldn't listen) ps use a bit of copper slip as long as it isn't carbon makes life so much easyier
