Campagnolo Record - A worthy Gran Sport Successor
The legacy of the Campagnolo Gran Sport was clearly evident in the company's derailleurs into 1985. The look of their derailleurs departed from the standard of the previous 30+ years in 1985 with the introduction of the C-record line; however, functionally things didn't change much until well into the 90's. For your perusal today is the Record derailleur. At a quick glance, it is hard to see how it differs from the Gran Sport, so I have included some side by side pics as well. There essentially two significant differences: 1) the lower spring cover is much deeper than that of the Gran Sport housing a longer spring; and 2) the pulley cage’s connection to the lower pivot is no longer centered between the pulleys but offset forwardly and upwardly. These changes allow the Record derailleur to have a greater throw and to be used with 6 & even 7 speed freewheels of a much greater spread in teeth. In other respects the Record is substantially similar to the Gran Sport...
