Fitting/sizing for a cross any sites?KMan1

Not getting a clear picture of what size cross bike I need or how to get fitted for one. 1st shop said they had no idea on a sizing a cross bike because no one in the shop rode cross, 2nd shop owner put me on a 57 and said "hmmm that looks about right" (not real confident on his opinion). Are there any sites that can assist me in deciding what size bike I need.

I'm 6'2" with a 33" inseam, long upper torso 185 lbs
I would be using the bike in the fall for cross riding/racing. Winter & spring would use the bike for traing on the road for MTB racing.

The only thing that has been told to me by a shop that makes any sence is that a cross bike should be a bit smaller that a road bike. If I am going to be using the bike for both, should I get the bike sized for cross specific and deal with riding a smaller framed road bike or should I get the bike sized inbetween both recommended sizes?

Thanks for any help

A CX frame should be sized 1-2cm shorter than your road bike for the seat tube measurement. This is due to the fact that the CX bike has a higher bb distance from the ground, and has taller tires than a road bike. Important factor here is standover height, which you want more clearance for hopping on and off the bike.

Second, the reach (top tube + stem length) should be 1cm shorter than on your road bike to put you in a more upright upper body position.

Go buy Simon Burney's book on Cyclocross. He has a very good chapter on the subject.

Good luck,
