Thank you! Yes, 9301 is the headbadge number on my 1989 Schwinn Cimarron. The headbadge number on my 1985 Schwinn Cimarron is coincidentally 1985. I have the 1985 through 1992 Schwinn catalogs. You are correct, Schwinn did not build the Cimarron after 1989.
I have never challenged the sequencing of the numbers on my 1989 Cimarron because I got it from the family of the original owner and the gift included all of the Schwinn documentation.
If you have a later bike that is documented as a Greenville bike, please present it.
30 years ago, bikes built in the 60's were scoffed at. Few people make jokes about a 1964 or 1965 Sting Ray now. I'd truly love to see the last REAL Schwinn made in The U.S.A. The Cimarron was onehelluva a bike. Mine both ride like Cadillac Fleetwood Broughams, but they can hang with any MTB ever built. The fact is that there are a lot of Schwinn bikes built after Chicago that will stand the test of time. Good stuff!
