Crosscheck sizing?
 

I generally ride a 56tt bike, what size Crosscheck should I pick up?

54

I would test ride a 54, and 56. I ride a 59 road and my CC is a 58. My cross race bike has a 57.5 tt with a 120 stem.

agreed, try a 54 and a 56.

if you're ordering from a shop and they don't have either one in stock, tell them that you'll put a deposit down but want to try both. they shouldn't have any problem selling the one you don't buy.
