Frame w/ 27.2mm seatpost - can I use a 27.0mm seatpost ?PeterRider

The difference seems to me so minimal that I don't see why it wouldn't work...

Thanks !

Maybe with a beer can shim.MR_GRUMPY

I wouldn't advise it, but the beer can shim trick might work. You would have to experiment to see how wide you would have to go. It would have to go down the seat tube at least 1 1/2 to 2 inches.
Unless this is some special seat post, just get a new one.
Don't think that will work either.Spoke Wrench

0.1mm is pretty darn thin and flimsy.

Trust me, it does make a difference. Ever tried to get a 27.2 post into a 27.0 frame?
If the post is special, or expensive, a single layer of soda can aluminum should give you .2mm. Try to make the shim long, at least 3 inches, to be safe, and line the edges up with the slot in the seat tube.
Otherwise, just pony up a few bucks and get a 27.2mm post. It's easier and safer, and your options are far and wide. You can sell the old post here or on Ebay to cover some of the cost, too.
