These Sunlite/Pyramid BB stands have a notorious habit of shifting under the bicycle it is suspending, rendering the bike ever so slightly angled to one side or another - but just enough that a misguided poke will send the whole mess flying to the floor.I once exhibited a series of vintage and modern lightweight road bicycles at a show wherein these stands were provided by the event organizers. I had the foresight to bring chainstay/seatstay hook stands (even then, not the best - crank mount stands are my preference) for my personal bikes, which served their purpose as intended during the event. On the other hand, we nearly lost a Cinelli MASH to one of these BB-shell stands, and had a few close calls with the other bikes as well.I might use one of these in an emergency, but I would not rely on it. Neither would I expect the vinyl-coated hook to refrain from damaging a thin, 1970's-era paint job - or a current-era clearcoat, for that matter.
