"Ultra-Glide" came out in the late 70s -- around 1978 IIRC.

The A9 and Delta are great headsets, and both are on-topic, although the
Delta just barely squeaks by with a 1983 introduction date. I installed
one on my tandem in the spring of 1984 and it's still going strong. The
A9 (and nylon B10) are somewhat older, dating from the late 70s, IIRC.

What I'd like to find are some MKS "Unique" pedals. Much nicer than the Sylvan, and earlier introduction.
