Not to overstate it, but for me, trying to decide which I like better between the NR and SR is almost (but not quite) like asking which of my daughters I prefer. They are both lovely, and they both share many of the same attributes and similar flaws (unlike my daughters, who are flawless).
|Virtually unchanged from 1967 through the early 80s, the Nuovo|
Record derailleur was the classic workhorse of Campagnolo's
|The first-generation Super Record was almost |
identical to the Nuovo Record -- the only real
differences being black anodized knuckles
and titanium pivot bolts.
When the U.S. Consumer Product Safety Commission (CPSC) got ahold of bicycle components in the mid 70s, they mandated little "cone of shame" collars around the adjuster screws on both the NR and SR models -- similar to the lampshade-like "Elizabethan Collars" that veterinarians put on dogs after surgery. The "cones of shame" don't interfere too badly with functionality, but I wouldn't worry too much about dispensing with them altogether, unless someone suffers from irrational fears of being fatally impaled on a tiny 3mm screw.
I like the solid, ornate, and almost archaic look of the Nuovo Record, but at the same time I can also appreciate the modern-meets-industrial aesthetic of the Super Record. To me, picking one over the other would be entirely dependent upon the year of the bike, and the style. A mid 80s top-level racer with pantographing and a flashy paint job screams for Super Record, for example. Otherwise, don't ask me to choose a favorite. Can't do it.
Anyone else want to weigh on in this one?
