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.

Sachs hub date code markings
The letters "I" and "Q" were not used, skipped due to similarity to "J" and "O". In 1982, the list was restarted with "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

After mid-1989, the week number and year of production was printed on the hubs with plain digits.
