I'm looking to get a cyclocross bike on the cheap (i.e. used) and thus don't want to waste a shops time asking fit questions and trying out stuff since I don't intend to buy there. I figure I can get into the ballpark based on my road bike size/geometry. What I'm not really sure is the cross riding position (I'm a noob to cross, looking to get started).

I currently ride a Cervelo S2, 56cm bike with a stack of 560mm and reach of 394 mm (i'm 6-1 for reference). It's very aggressive with a lot of drop for me, with a few spacers and a 110 stem. I also ride an older Bianchi steel frame in 57 (stack and reach unknown) with a 110.

I'm looking at a Specialized Tri cross in 58 that is stack of 611.7mm and reach 382mm. So it's 5 cm taller (though I use spacers on the Cervelo) and about 1 cm shorter. Should that be in the ballpark of the right size/position for me? Obviously, there is adjustability in stem length/angle and spacers.

Thanks.
I would use reach as your best guide. I'm 6'0" and ride a 60cm size.
