I'm looking to change the seatpost on my road bike as it's not quite long enough (would like to go to 400mm). I can see it's 30.9mm diameter but there aren't many options available in this size as 30.8mm seems far more common.
Am I likely to experience any problems if I put a 30.8mm post on the bike? Would it make a difference whether I go with carbon or alloy?
It's a Giant Defy 2 (2013) if that makes any difference.
Thanks.

30.8mm common? 30.9mm is the most common no?

Loads of 30.9 choice available.

It could slip, damage frame, cause injury, death or even the end of the whole human race.
