I signed up for a frame building class and I've decided to build a steel cross bike. The instructor has a spreadsheet for calculating geometry that uses Paterek's calculations. But you need to enter headtube angle, BB drop, crotch clearance, and inseam.

I've decided to look at some steel cross bikes on the market to get an idea for geometry. So far I've looked at the IF Planet Cross, Gunnar Crosshairs, and Surly Crosscheck. The Crosscheck, as expect, has a relaxed geometry. I was surprised that the Planet Cross seemed surprisingly relaxed as well. So far I'm leaning towards using the Crosshairs' geometry.

Any recommendations on geometry? Any other steel cross bikes I can look at for reference?

Planned riding will be cyclocross races and dirt randonneurs (D2R2).
