In reply to Kimono:
I've used a campsite (Don Bosco) just above Clusone (Val Seriana) - about 40k or so N of Bergamo. They have chalets and caravans for hire; not sure if that's any use?
Also, further afield, I did notice recently that Arco/Riva/Torbole are just awash with bike shops. Mainly mountain bikes but quite a few road bikes as well.
