Thats about it, if you don't shim out to the full ID of the frame's seattube,
[thats why the shim is there in the 1st place]
you have to buy the right size of seatpost,
and since you cannot declare what size the seat tube is in the frame by measuring yourself,
you have to take the bike to somewhere that can.
Kalloy is a budget brand of aluminum seatposts , and they are machined in many different diameters, if you want a seatpost that fits without a shim,
you have to buy one of the appropriate diameter ..
Cutting the slot in the frame wider to distort the seat tube down smaller ,
is a BAD idea.
