This is a Buyer's Guide to Italian racing bikes dating from 1984.

A quick and dirty count of the number of models using each brand of derailleur system gives:

• Campagnolo - 159
• Gipiemme - 13
• Ofmega - 7
• Rino - 5
• Huret - 4
• Gian Robert - 3
• Galli - 2
• Shimano - 2
• Simplex - 1
• Miche - 0
• SunTour - 0

I might guess that, in the UK, in 1984, for production road bikes, SunTour and Shimano might have topped the list, followed by Campagnolo, Huret and Simplex, with the rest nowhere.

Sometimes it can be a curse to have your own domestic components industry...
