29.8/30.0mm are both fine - nothing like enough difference to matter

Keep that original safe too!

FWIW 0.2mm did make a difference on my old On-One which was 29.8mm... I used a 30.0mm clamp with a half circumference homemade shim to ease tightening

Surprised the On-One wasn't 28.6 :?

post was 27.2 so as a general rule that would give you a 29.8 or 30.0 clamp eh?

Maybe...

I'll get me coat

Never had trouble with .2mm on the clamp size though, always had a mil or so movement and the same spare :?

I'm having similar issues with my VooDoo with Tange superlight, it takes a 26.8mm post but a 30.0 Salsa clamp is done up to its limit and still doesn't feel properly tight. Have tried a 28.6 Salsa which won't go near it. Thomson make a true 29.8 but not sure if its enough to make a difference. :?
