A TRUE CLASSIC ... Masi Gran Criterium (1973/74)

Bike purchased in 1976 (used in great condition).  All  original Campagnolo Groupset & Frame Pump.
Note: frame a "Brev . MASI" hand built in Italy and bike built in Carlsbad, So.Cal.
I changed out to a Shimano groupset & cranks.  This allowed me to fit a Six Cog rear cluster, in the narrow rear. Original was a Five Cog Cluster with one "Cross-Over" ratio, so only provided Nine Ratios.
