Frame size help

edited October 2010 in MTB buying advice
I've purchased a 2010 cube gtc reaction pro (carbon) at a reduced price. I'm yet to ride it because I can't decide whether to keep it or not. The thing is, it's a 20" frame (though from bb to top of seat tube it measures 18") and I'm 6' 3" which is right on the limit of what they recommend. I've had to purchase a 450mm seat post to accomodate my preferred saddle height and have also purchased riser bars as I prefer the riding position. I'm now wandering whether to send it back! The thing is, having tried it out on the short section of road outside my house it seems to ride fine, but I can't be sure that it is not too small for me as the riding position is somewhat different (more racey) to my current bike. I like small frames (my current bike is a rock lobster 19" which is right on the limit of my fit, but I love it) as I like to be able to throw the bike about a bit. However, can anyone offer me advice on what to do? What are the potential pitfalls of purchasing this bike given the information I've supplied.
Any advice would be greatly appreciated.
Thanks

    This is a classic example of how frames can vary so much for a 'listed' size - one mans 18 is often not the same as another! Especially when regarding reach.

    On the face of it it does sound a little too small perhaps - 450mm seatposts at full whack could possibly cause problems to the frame. But how does the reach feel?

    I am also 6 foot 3 and have a Rockhopper 2009. It is 21 Inch and anything smaller than that just feels wrong.

    Is there anyway you can at least sit on a bigger one - in an LBS or something - just to get a feel for the size?
