Sierra or High Sierra?

[undercover_poe]

I've never considered this bike collectible. But here is mine:

No idea what year it is. Found the serial number but can't find a look up that covers the 80's

Head Badge Dating-
4 digits (post '82 [or 1976])- first three digits are numerical day of year,fourth digit is last digit of year(you pick decade).

Try to find it from color & graphics here(I'd start with '85)
I'm not an expert but my notes say:
Taiwan('79-'81)-Bottom or Dropout- Gmmyy (G=Giant) (ie.G04813=Apr'81).
Sierras were later than '81 but maybe this applies to your bike. Also, see if the headbadge has a four digit code stamp to find the date per above.

Giant manufactured bike. G058? = month 05 May, year 80 something. Can't read the last digit, possible 6 so 1986?

View attachment 403919 View attachment 403920 View attachment 403918 First year Sierra , Chicago frame , 84 Schwinn went to Taiwan for Sierra & High Sierra models , here's my 3 examples

Some Sierras were built by Murray in Lawrenceburg after Chicago was closed down. But I think you're right about the High Sierra, they all came from Giant.

I have this Schwinn bike and am trying to find out what model it is. The serial # is
DU500506 and the badge # is 1433. All I have figured out at this point is that it is probably a 1983. Sierra or High Sierra. Can anyone help?
Thanks

Congratulations! From what I've read, April 1983 was the last month for Chicago built frames, meaning you have one of the last bikes built in Chicago.

Here is one I just got. Looks like air up tires and lube chain is all it needs. Are these worth anything? And is mine an 83 as well?

Frame head was stamped in March '83. Post a close-up of the 4-digit no. stamped in the headbadge, that will indicate the date the bike was built.
