I still use a flickstand (made by RhodeGear...out of business...?) on my 25+ year old Soma Sport. It's the slickest little device that adds great stability to the bike and it can be leaned against anything without any worries it's going to fall. Even with different shaped downtubes I would think some company could come up with one...this is simple technology. A loop of velcro wrapped through the front wheel and around the downtube would be the prototype of this technology I'd think. It isn't often you see great simple technology fade out with no replacement. Odd.

You can google for a photo...here's one I found.
