Restoring a Bike to its Old Glory

I have been spending so much time talking about Campagnolo components I am tempted to start another blog in that name; this is another one. A while back I identified all the Campagnolo components on my Specialized Allez. All the components were Nuovo Record, except the shifters and derailleurs that had been "upgraded" to the C-Record shifters and C-Record era Chorus Derailleurs below.

While these are very nice components, I just felt they did not belong with the Nuovo Record parts so I endeavored to restore the old style drivetrain components to their old glory.

Here is the new side view.

The classic Nuovo Record Shifters

The front Derailleur with the very classy clamp.

And the pièce de résistance, the Nuovo Record rear derailleur.

This little gem was lasted almost unchanged for 16 years as the must have racing derailleur. There were some incremental changes however, each getting it's own yearly patent number. I looked to find a late model; this being a Pat 84. There are simply a jillion of these derailleurs out there but they are still quite pricey. I actually found this one in Poland. Turns out the pulley back plate was bent (a very easy fix) and the pulleys are Shimano. The OEM pulleys for these are quite pricey and hard to find, but there are some high quality replicas for about $30, which I will be purchasing in the near future. The NR derailleur was rated for 6 speed, but handle pretty much any tooth count about up to 8 speed. I have retained the 7 speed 13-23 freewheel for now, but I have a 5 speed in reserve. My reasoning for the 5 speed instead of the 6 speed, is because there is something still classic about a 10 speed race bike.

I have the Regina Extra chain that came with the other components but it is a couple of links too short. I have still run the chain through the derailleurs and it works great. I threw on a SRAM 8 speed chain and while it functioned properly, it was not as smooth as the Regina. I posted a request for some matching links on the Roadbike Review Vintage forum, and a gentleman that goes by "sewup dude" is sending be 4 links in the mail gratis; vintage cyclers are good people.
