I bought this ferraroli bike in France from beginning of the nineties ( I rebuilt it quasi full dura ace 7400 range setup - see road readers bikes)
To convert the left command int a 3 chainring able command, it was equipped with this accessory that modify the cable stop "lengrh"
this is the first time I see this
how old is it - when did this appear ?
and I would like to find another one but no success till now - seems pretty rare ?

and now having been bitten by the vintage roadie bug ! is this serious doctor ?
