Yeah, those too. We were a Suntour household, so Power Shift ratchets held sway, but my friend's house was Francophile and his Simplex Retro Friction wrap-spring clutches did the job just as well.
I prefer Suntour too (the cyclone derailleur IMHO is better than anything Simplex make), it's only the Retrofriction that stood out of the Simplex line-up.
FTFY.
