get a tape measure and measure the out side circunfrance of the wheel. This is you number. OR put a white dob of paint on the tyre and roll it in a strainght line until the dob of paint makes a 2nd mark, (on a path way etc) measure the distance. this will be the same as the first option. Generally its required in mm.

There's a size chart on page 15 of the manual that has great instructions for measuring and entering the wheel size.
You can get the manual from Sigma's website at this link.
Method "B" is the most accurate way -- make a chalk mark on the tire and stand the bike up next to a wall with the chalk mark at the bottom.
Have a friend make a chalk mark on the ground at that point.
WITH YOUR FULL WEIGHT ON THE BIKE, move forward for one rotation of the wheel -- until the chalk mark is on the bottom again. Do this as straight-line as you can.
Have your friend make another mark on the ground at this point, and measure the line between the two points on the ground.
This is the wheel circumference, and if you do this with normal tire inflation and with your full weight on the bike, it's the most accurate way to calibrate your cyclocomputer.
If this helps, please be sure to hit the "thumbs up" for me.
If not, of if you have questions, use "add comment" to post back here, and I'll do my best to get you going.

SOURCE: i need the settings
All you need to do is measure the diameter and do the math or for precision, roll-out one revolution on the ground and measure it in millimeters and divide by 1.61 (or multiply times .621). (Consult chart or figure yourself by measuring from the top of the tire to the ground in inches.) Measurement X 25.4 x 3.14 / 1.61 = ws ( / is divided by) There's a chart in the link below. I believe Columns E and F apply.

The manual explains how to measure your wheel exactly and set it into the computer...
