ACS STOKER STEM TIMELINE

[deeman]

I am just a little curious,I was wondering if anyone knows up until what year ACS produced their Stoker stems.I have seen 81 and 82 dated ones for sale.I have possibly seen an 83 but can't be sure.I had one bitd in about 84/85 but it may have been a remnant from an earlier bike.I would imagine that they were produced up til 85 when the rotor and subseqeunt stems came out.Am I wrong?has anyone ever had or still have one stamped 84 or even 85?Any help appreciated

Do you mean was the ACS Rotor the first de-tangling device?If yes then the answer is yes!
