Q:

Please help Identify Italian frame

59-60cm frame, Sun Tour Superbe Pro Brakes, Shifter, front and rear derailleur, and complete Crank is Sun Tour Superbe Pro. Campagnolo head set and pedals. Cinelli 64-40 handle bar and Cinelli stem. It's an Italian make I'm sure. Serial number on the BB is BMZ 09 is all I can make out. Any help is greatly appreciated! 

A:

BMZ presumably stands for Biemmezeta, an Italian manufacturer from near Milan who did a lot of contract manufacturing for a lot of places (e.g. Performance Cycles) as well as sold bicycles under their own brand. More details on your location may help narrow down the bike's pedigree. 
As Daniel R Hicks estimates the date of the bike in the comments, it should be noted that BMZ was popular in the 1980s.
