The solution a Feedback Sports - Velo Cache from REI. It was easy to assemble and is very stable. Now the vintage bike that started me into this hobby, the Nishiki Professional - all Campagnolo Nuovo Recrod Gruppo (bottom) and the latest and likely only grail bike I will ever restore "H. Hagiwara-Erba" (top) will keep me company and leave enough room we can even set up the tandem on our trainer in the winter to ride. Thanks again for thoughts and suggestions.
