Notes from My Father’s Diary…

January 1951… On Bicycle Wheels!  To avoid uneven tyre wear and to provide reasonable operation of the rim brakes, wheels must be kept dead true. They very often go slightly out of true, however, and if the cycle is inverted and the wheels spun it is usually apparent to the eye. To make certain at which point or points a rim is out of true, it is a good idea to hold a piece of chalk lightly against it at the fork and then spin the wheel; the rim will then show marks at the points which require adjusting.
