Custom wheel size
To setup a custom wheel size, measure the bike’s rollout (Figure 31, the distance
the bike travels in exactly one revolution of the wheel), then setup the computer.
To measure rollout
Tools required: helper, pen, and measuring tape
1. With the valve stem of the wheel directly over the floor, sit on the bike.
2. Have your helper mark the floor at the valve stem.
3. Roll the bike forward one revolution of the wheel, so that the valve stem is
again directly over the floor.
4. Mark the new location of the valve stem.
5. Measure the distance between the marks. If needed, convert to millimeters.
The result is your custom wheel size.
