Determining the production year of a Sachs hub

Until 1957, a two digit number on the hub shell or internal components was used to indicate the year of production of F&S hubs. After that, a single letter representing the year was used:

("I" and "Q" were not used, skipped due to similarity to "J" and "O". In 1982, the list was restarted with the letter A)

  • A = 1958
  • B = 1959
  • C = 1960
  • D = 1961
  • E = 1962
  • F = 1963
  • G = 1964
  • H = 1965
  • J = 1966 (I is skipped)
  • K = 1967
  • L = 1968
  • M = 1969
  • N = 1970
  • O = 1971
  • P = 1972
  • R = 1973 (Q is skipped)
  • S = 1974
  • T = 1975 (Marking moved from hub shell to brake reaction arm, the lower letter is the year, the upper is the month)
  • U = 1976
  • V = 1977
  • W = 1978
  • X = 1979
  • Y = 1980
  • Z = 1981
  • A = 1982 (List restarted)
  • B = 1983
  • C = 1984
  • D = 1985
  • E = 1986
  • F = 1987
  • G = 1988
  • H = 1989

Month codes:

In the period 1975 to 1989, a production month code was added above the year code, using the following pattern:
(Again, "Q" was skipped)

  • N = January
  • O = February
  • P = March
  • R = April
  • S = May
  • T = June
  • U = July
  • V = August
  • W = September
  • X = October
  • Y = November
  • Z = December
