My Cannondale Scalpel frame is going to arrive soon (hopefully) and I wrongly assumed that it takes a 27.2mm post when in fact it's a 31.6 which begs the above question ???
I have a nice Syncros carbon seatpost in 27.2mm size but would you shim this by this amount going into a carbon frame ?
Looking at most shims they are 80mm long which doesn't seem much although comparable to the min insert line on the seatpost. Dunno ? :?

NOt carbon but i have shimmed my thomson post onto my morewood as seat tube needs reaming.
I suppose as long as your seatclamp is decent enough to put sufficient clamping force on the area - no problem.

Buy the right size post.

Seems a shame to scrimp and not get the proper sized post.

Could invalidate warranty too ...
