I have a question for Scrod!

I own several bikes, none fixed gear or ss. I want to buy a Kilo WT.
I am 5'8" with a 31" inseam.
My typical center of saddle to handlebar measurement for my road bike is 25.5" and 24.7" for CX. My saddle height is roughly 26 3/4 (center of bb to center of top of saddle) but that is with low-stack clipless pedals.

The geometry chart here: http://bikesdirect.com/products/merc...tt_wt_xiii.htm
My crit bike is a 52cm CAAD10 with a 100mm stem (chart here http://www.cannondale.com/catalog/pr.../category/916/)

The Kilo WT 53 looks like it may be a bit large? And the 49 just sounds absurdly small...
Which size would you recommend?


(And nobody better accuse me of not giving enough information!)
