I have a 1989 Bottecchia SLX that I bought new back in 1989. A few years ago I replaced the original Modolo handlebar and stem with this:
Since that picture was taken, I have replaced the original Campy drivetrain with Campy Athena 11 speed.
I know that some of the purists here may object, but the new drivetrain is easier for me to use. M Colnagos, including the Master, all have new Campy Record and it was getting to be a PITA to go from DT shifters to brifters. And, to be honest, the old Campy brakes do not work nearly as well as the new Campy skeleton brakes.
Unfortunately, I can't wear this skinny Italian racer jersey ... there was a time, however, when it fitted just fine!
