Roll Out Method
The roll out method will provide the most
accurate computer calibration and can take
into account variables such as inflation pre s-
s u re, 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 pre s-
s u re, place the valve at the 6:00 position (at
the bottom) directly over the start of the mea-
suring 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, multiply inches by 25.4).
Use this number to replace the default
(default values are 2054 for wheel one, and
2113 for wheel two) when pro g r a m m i n g

your computer.
