Seatpost - to shim or not to shim?

Quick question.
Working on an old frame conversion.
Seat post is knackered and needs replaced but is old size at 26.3mm and a tricky size to find. 26.2mm is fairly readily available.
Reckon i'll need a waffer thin shim for .01mm!?

old beer can or some fine grit sand paper would shim it up cheap.

My frame is currently shimmed with a bit of CousCous box. Doubt you will find a 26.3 if im brutally honest!

^ Nah, did'nt think so either. Shim it is then. Will need to suck it and see.

tar.

Its fosters can for me, seriously dude aluminium can is basically an accepting repair material. Shim away! Just cut a slimmer shim to get a nice fit.

*accepted :s

yeah alu can, a good cheep shim - but it's only for a 10th of a mm?

Can I get a reeeewind!

Err... I bought a seatpost and funked up the measurement...I don't recommend shatter proof ruler as a substitute for vernier calipers.

So... my seatpost needs to be 32.4mm but I gots 31.6mm.

My question:

Would a shim be a suitable solution to this problem or should I get a refund and try to find a Thompson 32.4mm seatpost instead?

Thanks muchly.

Send it back and get the 32.4 shims are break fix only

i'd rather get a size to large, measure the depth tape it and sand it down as apposed to a loose seat and chim (see what i did there....)

yeah dude on your bike i would just go for the right size, its too nice for a ghetto shim.
especially the seatpost........

use a proper shim. the pegoretti takes an odd 29.4 size so i used a U.S.E thermoplastic shim.

Seconded, I use one on my mountain bike. Awesome piece of kit.

Luckily the dude on ebay said I can have a refund so I now need to locate a new 32.4mm seatpost.

Mr Smith I had a look at those USE shims but the one I need is £10 as I need an odd size perhaps?! Will just try and find a proper fitting seatpost. If I really struggle finding one, I reckon I'll get the USE thermoplastic shim.

Cheers dudes, helped make my mind up.

This thread can now return to the murky depths of the forum.

It could be worse--you could have bought a 32.4mm seatpost and your seat tube could be 31.6mm.
