They remained fairly popular in Britain (where they were called "breeks" or "trews") in the years between World War I and World War II, but eventually were eclipsed in popularity by racing tights, even among the vast majority of cyclists who never raced. Invariably referred to as "knickers" in the US, they lived on as a just-past-the-knee variant of racing tights reserved for colder-weather riding.
