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.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.
