Dura Ace with the funky large pedal threads ?

Was this the AX or EX ? Did it have a trade-name that everyone knew it
by ?

Thanks,

AX, aka the "aero" group.

They were most famous for fragility: I think the spindles and cranks
broke a lot.

The previous generation of stuff was Dura-Ace EX:

*Shimano's* name for them was "Dyna-Drive". It was available in
Dura-Ace AX:

Dura-Ace EX:

600 AX:

and the Deore touring group:

FWIW: I *had* a Deore crankset with the DD pedals way-back-when. They
were pretty nice- a really large, flat platform that fit my really
large, flat feet. Too bad I sold the bike I put them on (one of the old
fillet-brazed cro-mo Schwinn Superiors). *Sigh.*
