Sometime around '83 or '84, I had my Ritchey repainted and some braze-ons added. While it was in work, I got a Ross Mt Whitney from the guy who handled marketing for Ross. (He was a regular at events like Crested Butte, and I also knew him from tradeshows where we both displayed.) Anyway, I rode the heck out of that bike. While it certainly wasn't a Ritchey, it was a well made bike and rode well. I kept it as a loaner for years before selling it. This link appears to show a similar bike, though I think mine may have been preproduction http://mombat.org/1984_Ross_Mt_Whitney.htm
