I recently got 2010 Pro Fly X. I'd like to get an after market quick release seatpost clamp. According to the web-site, it has 27.2 seat post. What would be the appropriate size seatpost clamp?

should be 31.8

thanks...

You're right. I just measured the outer diameter of the seat tube after taking out the current clamp. It show 3.2cm --> 31.8mm it is.

Sometimes the original clamp will have its sized engraved on it as well so you can double check...

Now that you have the size...hope, makes nice clamps and wheel skewers.

I don't think it was the case with mine. 34 was stamped on the bottom side of the original clamp, when the inner diameter of the clamp and the outer diameter of the seat post measures 31.9 mm. ???

I went ahead and ordered el cheapo from here. I'll mess around the neighborhood a bit before I take the bike out to a trail with the new clamp.
