Note. They are called Record cranks, but the full group is sometimes referred to as Nuovo Record. That's because "Nuovo" is added to the name of some modified parts as for example the rear derailleur. The name Nuovo Record group is seen for the first time in 1982 Olympic catalogue (printed in USA) and that might be a misstake. The Italian catalogues never calls it that, it's simply just Record.
