Bullseye first released cranks in '74 Adam. Do you have a picture of the ones you're referring to?

Back in the early days, there were actually 6 or 7 versions of cranks and up to a dozen prototypes:


1st gen  -  V1 19mm spindle    - Side bolt spider mounting, Hollow spindle 1974-1975+

1st gen  -  V2 22.2mm spindle - Side bolt spider mounting, Full hollow spindle, No end cap, No safety washer key. 1976-1977+

1st gen  -  V3 22.2mm spindle - Side bolt spider mounting, welded safety end cap and safety washer. 1979-1980+

2nd gen -  V1 22.2mm Spindle - TA Cyclotourist spider plate mounting. 1981-1985+

2nd gen -  V2 22.2mm Spindle - TA Cyclotourist spider plate mounting. Safety Key washer non drive side. 1985-1990+

3rd gen  -  V1 22.2mm Spindle - 3 piece Hurricane arms, Tapered drive to TA Spider plate. 1992+

All dates are estimates based purely on original mechanical drawings,
documentation & sales figures/receipts coinciding with respective years!

I trust this information will now put you in good stead to know what is what.

And that's from a BULLSEYE Authorized Distributor!

Thank you both.

I'm fairly certain that the ones you're referring to, as they're most commonly called 1st Gen for BMX are the set introduced in 79-80, they look very similar to those on your Torker Adam but without the TA mounting...

That's the ones Chris, I have a set already and wanted to check timelines before fitting them to a frame I have.
