CRers,
Any thoughts on just why the trasition from ball bearing to sleave style be arings happened in the 60's? Was it strickly driven by price/profit margin? Even on the high end changers where "price is no object", they switched to the inferior style. Campy, which many consider the standard, switched betw een the Record and Nuovo Record in 1967.
Who was the last manufacturer to make the switch? What year? Bullseye and o thers came to our rescue not that long after with their nice alloy sealed b earing replacement pulleys.
