We have mangets cyclecomputers into six groups according to the number used in calibrating them. Different manufacturers have used different brands of tires to calibrate -- or have done calculations based on nominal dimensions -- so there can be a slight inconsistency what mm size are computer bike magnets the numbers in the tables and the most accurate number for your bicycle. Bike ms citrus tour ride with gps which a national standard identifies by outside diameter actually vary depending on the tire cross section.

For example, a 20 x 1. It is less than 19 inches in effective diameter.

See https: The table below is based on rim sizes and tire cross-sections what mm size are computer bike magnets than than nominal sizes. The chart below doesn't list all possible tire sizes, but does list the most popular ones. If your marked tire what mm size are computer bike magnets falls between two sizes shown on the chart, interpolate the appropriate calibration number between those above and below, or for greater accuracy, do a roll-out test keep reading Both of these numbers are in millimeters.

For example, a x 28C tire has a nominal width of 28 mm on a rim with a bead seat diameter of mm. To get an approximate diameter in mmadd the bead seat diameter to twice the tire width since the tire depth comes into the diameter twice: Multiply this by pi 3.

Frequently Asked Questions about Bicycle Computers There are no standard wheel sizes in the cycling world - i.e. the circumference of a x23 The best way to determine wheel factor (i.e. wheel circumference c) is to do a wheel roll-out test To convert inches to mm go to and type in '88 inch to mm'.

Thanks for posting this. I had stationary bike computer. idea myself but you saved me the math. I whzt a 4 spoke crankset and I found that my cadence results were more consistent when I used 2 magnets instead of 4.
