Er, um - I'm not quite sure I understand what you're saying here - I would have thought that the only thing which changes the distance calculated by the cycle computer is the circumference of the wheel. The postition of the magnet has nothing to do with the circumference of the wheel, or with the number of revolutions the wheel makes in a mile. The speed at which the magnet passes the sensing probe will change with the distance the magnet is set on the radius of the wheel, and this might alter the signal which the sensor detects, but the number of revolutions per mile will not change…
