Interesting. That's the first time I've heard this.
the crown race was more delicate, I have seen those go bad, and more frequently crack from being forced on a “no passa” crown race Seat.
The Super Record crown race was much thinner than the Record crown race in order to keep the total stack the same as the Record headset (the aluminum cups needed to be thicker to provide support to the steel race inserts). This made it more delicate that the Record headset crown race.
