Roll Out Method
The roll out method will provide the most accurate computer calibration
and can take into account variables such as inflation pressure, rim width and rider weight.
1.Extend a tape measure out to 3000mm (120 inches) and lock it in place.
2.With your tire inflated to its proper pressure, place the valve at the 6:00 position (at the bottom) directly over the start of the measuring tape.
3.Roll the wheel one complete revolution until the valve stem is again at the 6:00 position. Read the tape directly under the valve and note the distance in millimeters. (To convert inches to millimeters, multi- ply inches by 25.4). Use this num- ber to replace the default (default value is 2148) when programming your computer. (See figure 6)
