ATTN: BAseliNe Computer Owners: if you purchased a BAseliNe Computer (BC 400, BC 1200, or BC 1200+) after May 2012, please check the date code 
on the back of your computer before referring to the chart above. if the 5 digit date code ends in the letter “M” (for Metric), you have the newer “auto convert”
software and should use the “New 2012 BAseliNe” columns.

km/h: 

WS = mm x 3,14

mph: 

WS = mm x 3,14

 

divide by 1.61 for MPH setting on older models!

Wheel size not shown on chart? Do the following:
The correct wheel size measurement is the outer  
circumference of your tire in millimeters.

(For older SIGMA computers that did not have the auto  
convert feature, divide circumference by 1.61 for MPH!)

1.

 Measure overall height of the tire in inches;

2.

 Multiply by 25.4 to convert to mm.

3.

 Multiply by 3.14 to get the circumference of the wheel.

4.

 

Divide by 1.61 for MPH (only for older models)

Auto Convert Models: Any computer that ends  
   

in “06” or “09” + ROX.

   

– ex. BC 506, BC 1009, ROX 9.0

Non-Auto Convert:   Any computer that ends in “00”
   

– ex. BC 400, BC 500, BC 1200
