Seatpost shimming 26.8-27.2

[brianj]

Have a 26.8 seatpost that needs to go into a 27.2 frame. So 0.2 mm space all round. The thickest shim stock that can be sourced form my mates engineering place is 0.13mm, and not sure this can be machined... any ideas?

a couple of sheets of cut from the can of your favourite beverage?

0.13mm is smaller than 0.2mm. Machining that wont help.

 

Might be better to get a new post (if your's isnt fancy/expansive). Adding a shim to the post could cause the frame to flex where it shouldn't and cause a crack. Seen it happen before.

I meant getting one machined separately, as opposed to using shim stock.

 

Beverage cans are apparently 0.3 minimum
