How To Determine Wheel Size For A Bike Computer BikeBlogger

The easiest way of how to determine the wheel size for a bike computer is to roll the bike on the ground. First, pump up the tires. Second, place a tape measure on the ground. Third, line the front wheel up with the tape measure with the valve stem as a reference point. Fourth, roll the bike forward next to the tape measure one complete turn of the wheel. Fifth, the place where the wheel stops is the measurement you need to input into the bike computer. The unit conversion from inches to millimeters is (inches x 25.4 = millimeters). Sigma is a bike computer manufacturer and they are really good at providing helpful installation videos, for instance, here are links for the Sigma BC 8.12 ATS.
