Spoke Size / Spoke Length Database - What size spokes do I need?

assumed ERD of 605 for the open pro, hub numbers based on yogarup hub info, and using his mighty quick Spocalc widget:

Front

• Radial 270.0 mm
  
• One cross 272.9 mm
  
• Two cross 280.8 mm
  
• Three cross 292.2 mm
  
• Four cross 305.1 mm
  
  

Rear

• Radial 269.6 mm
  
• One cross 272.4 mm
  
• Two cross 280.3 mm
  
• Three cross 291.8 mm
  
• Four cross 304.7 mm
  
  

Best get a second opinion though, or at least check the measurements yourself with the hubs and rims you're holding. I'm just using the numbers I found on the web afterall, and I'm assuming the flange measurement on yogarup is a low one (although 67 might not be that low - bikeforums suggest might be 44, but then the c-flange measurement changes too?)
