Wheel Size Setting
The wheel size setting number is equal to the
distance, in millimeters, that your front wheel
travels during one complete revolution. Each
time the wheel magnet passes the sensor unit
on your fork, the sensor sends an impulse to
the computer telling it that your wheel has
completed one revolution. The computer cal-
culates this distance vs. time to give you accu-
rate readings for the various modes.
Determining Wheel Size Setting
There are three methods for determining the
wheel size setting. For the most accurate
computer readings, it is best to measure the
actual distance that your wheel travels in one
complete revolution. This method is called a
wheel roll out.
Method One: Wheel Roll Out
• Perform the wheel roll out on a hard, flat,
smooth surface such as a garage or
basement floor.
• Make sure your tires are properly inflated.
1. Position your bike so that the valve stem of
the front wheel is at its bottom most position.
Mark the spot on the floor directly under the
center of the valve stem using a piece of tape
or chalk.
2. Roll the bicycle forward in a straight line,
while putting downward pressure on the handle-
bars to simulate rider weight. When the wheel
has completed one revolution and the valve stem
is at its bottom position, mark the floor directly
under the center of the valve stem with tape or
chalk. Measure the distance between the two
marks in millimeters. (Note: Conversion of in. to
mm. is 1 in.=25.4 mm.) This is your wheel set-
ting number. You can repeat this procedure and
average your results. We recommend that you
record your wheel setting numbers here for
future reference.
Method Two:
Measure wheel radius (including tire) in
mm and multiply by 6.2832=Wheel
setting number.
Method Three:
Refer to the following chart and input the
number that corresponds to your tire size.
(Note: Actual size of two similarly marked
tires from different manufactures can vary
significantly, making this method the least
accurate.)
