I was only thinking the other day that back in the 80s for racing it was all campag gears. Super record for the rich, NR for those on a normal budget and GranSport for winter bikes or bottom budget. Huret or cheap shimano, simplex and suntour was seen on mass produced bikes and better suntour was for touring bikes. And shimano crane was rarely seen.
If I could now go back 40 years and spec a racing bike, I'd have suntour gears. The mechs were well designed, had a jewelled finish and were far lighter than any of the others. And their retrofriction levers were the best working levers on the market
