speed. The wheel size must be set
in millimetres

WHL2). Use this function if you have two bikes. The wheel size which
is displayed when you leave the wheel size setting mode, will be
used next time you start exercising.
TO FIND OUT THE WHEEL SIZE OF YOUR BIKE YOU HAVE
THE FOLLOWING ALTERNATIVES:
METHOD 1. The quick way.
Check the wheel diameter (in inches) which is printed on the front bike
wheel. On the chart below, find your wheel diameter in inches on the left
and match it with the wheel size in millimetres on the right.
WHEEL DIAMETER WHEEL SIZE SETTING
(inches) (mm)
26.0 2080
27.0 (700*32C) 2155
28.0 (700B) 2237
METHOD 2.
Measure the circumference of the wheel by stretching
a tape measure around the outside of the wheel.
If you measure in inches, convert the value to millimetres
by multiplying the number of inches by 25.4 mm. mm
Subtract 4 mm to account for your weight on the bike. - 4 mm
The four digit value for the wheel size is mm
METHOD 3. The most accurate way.
For this method ask your friend to assist you. First, mark the tread of your
front tire with a line. Match this line with a line drawn on the ground. Sit on
your bike and have your friend walk you forward for one complete wheel
rotation. Draw another line on the ground exactly where the mark on the tire
touches the ground. Measure the distance between the two lines on the
ground to get your wheel circumference. If you measure in inches, convert
to millimetres by multiplying the number of inches by 25.4 mm.
