Okay this will stretch some brain cells.
1979 JC Penny bike made in Japan.
Unusual Shimano components.
The longest lugs I've ever seen (except maybe some Hetchins).
Two (2) Serial numbers!
Shimano Titlist deraillers
UG chain (uniglide chain, the fastest stretching chain ever)
Suicide levers that work very well.
Tourney center pull brakes with built in quick release half saddle.
early One-Key crank extractors built in.
Selectra cranks. Spockets twist lock in to place and are held by 1 small screw (each).
the most minimal branding. One tiny JC Penny decal below the derailleur. No name badge with just a bike logo.
Specs decals on the top tube. gearing and weight. (note the Schwinn Super Le Tour 12.2 was being sold at the time. 700 grams lighter).
Inverted bb cups used on some of the FFS cranks. No shields or seals to keep the grease in and the crud out.
9278565 and J9S7388
The first 9 in the serials seems to suggest 1979. One shimano crank has an April 1979 date code.
What factory?
Note the braille like dots on the crank spider.
