- 30.9 to 31.6 seatpost shim solved!!!
For all those that have been wanting to fit a 30.9 post into a 31.6 seat tube, I have found a cheap answer that doesn’t involve cutting up coke cans…….
Purchase a USE aluminium seatpost shim sized 31.6 – 32.4, I bought mine from chain reaction for about a fiver.Posted 6 years ago
There is already a slot cut down the length of this already, simply trim 4mm off one side, effectively widening the slot.
Slip shim into the seat tube, if the gap in the shim has closed up it may be necessary to trim a tiny bit more off, but don’t go mad.
Slide your post in and it should be a nice slide fit.
Sit back, admire your work and feel smug.curlie467Member

It says no-stock but it did when i ordered mine but still got it within a week.
Oh, and when i searched for one it took about 10 seconds on google.ti456nealMember
I trimmed mine with a normal pair of kitchen scissors as it’s very thin aluminium.Posted 6 years ago
I did try to get a 31.6 shim but everywhere said out of stock, even rang USE as they are local to me, but no luck.
Sorry guys, didn’t mean to waste anyone’s time, just trying to offer a solution to a problem.
