Here's a weird story. Years ago, my wife bought a blue Bianchi with Shimano 600 group. Last winter, I bought a blue Miele with Shimano 600 also. When I showed my new Miele to my wife she said the paint was identical to her Bianchi. We put the bikes side by side and the paint was identical. Later, after removing the rear wheel of the Miele, I had a close look at the rear drop-out. It said Bianchi!
Both bikes were made in Japan, and very well made. It seems that both Bianchi and Miele had at least some frames, perhaps whole bikes, made by the same Japanese contractor. Japanese frames don't get the respect they deserve.
I have a Miele Beta frame I think. It's a mid-range model, but, it has similar geometry to steel Colnagos, I'm looking forward to building the bike up someday.
