context_page_description: Friction disk shock absorbers or André Hartford dampers were an early form of shock absorber or damper used for car suspension. They were commonly used in the 1930s but were considered obsolete post-war.
context_section_description: Motorcycles of the same period, through to the 1950s, that used girder forks also used friction disk shock absorbers. These were often provided with a large handwheel, so that they could be adjusted easily during a ride, or even whilst in motion.
