The Surly Crosscheck are actually meant to have that much spacer, usually touring bike (although it's a mixture of everything) as a guideline tend to have a higher cockpit than usual for comfort.
it's also why the crosscheck measurment is unusual, a 54cm have a 56cm top tube, a 56 have a 57cm top tube etc., simply because it's build with lots of spacer in mind (higher the handlebar, closer it is to you);
??? Wouldn't it be better to have a short top tube for the frame size, that way the headtube/seat tube would be longer which would raise the cockpit up. In fact what you really need is a compact frame with a very long headtube but retaining some standover (as the top tube would slope down).
