Campagnolo's Nuovo Record 1020/A rear derailer

Nuovo Record (literally, "New Record") was Campagnolo's third revision of their Gran Sport derailer, following the brass 1963 Campagnolo Record dérailleur. The Nuovo Record was introduced to the world in 1967, and formally entered the mass market in 1968 (including some early 1967-production RD's).

Pulley cage stop, 1967 only:

(To be discussed)

Pivot bolts, 1967-1971 vs. 1972+:

Until 1971, Nuovo Record's lower pivot bolt was a single piece of chromed steel. By 1972, a plastic friction washer had been introduced to the design; necessitating that the cylindrical area of the bolt near the head - where the washer sits - be reduced in size from the initial design.

Consequently, post-1971 bolts must be used with the friction washer; even with earlier derailer bodies. These washers are not necessary on pre-1972 bolts; neither will they fit.

Pulley cages: 1967-1986 vs 1987

All Nuovo Record (and Super Record) pulley cages have a steel nut casted into the aluminum outer pusher cage - with exception to the final 1987 RD's. Both pulley cages are equally compatible, but for the person who demands perfect accuracy, this is one other detail to keep in mind.

Please note that the pulley cages shown are second-generation Super Record. The pulley cage shape is not representative of Nuovo Record.


Though the main body of all Nuovo Record derailers are anodized, the relative shine varied. Early RD's have glossy clear anodizing over a satinesqe aluminum finish, which is carried over to the pulley cage. By the late 1970's, the main body became noticably shinier (though still anodized), and the pulley cages were revised to suit (additionally, the cage castings were revised to have less bulk). The final 1987 variant reverts to a more milky appearance, nearly identical to that of C-Record.

Pivot pins

The Nuovo Record's parallelogram pivot pins were originally aluminum pins (inserted through brass bushings) peened at each end. In 197? these pins were replaced by hollow, chromed brass (steel?) tubes that were peened in a similar fashion. Each style is conceviably compatible with the other, if you can locate the original replacements.

Replacable return spring

Until 1985, Nuovo Record's parallelogram return spring was completely removable and replacable. The 1985, 1986, and 1987 variants were revised with a non-removable spring built into the lower half of the parallelogam.

Dating and "PATENT" marks:

The very first 1967 Nuovo Record RD's were marked "PATENT CAMPAGNOLO" at top.

By 1968, this had changed to a simple "PATENT" marked on top of the derailer's body. This variant remained until 1969.

In 1970, the now-familiar "Patent-7x" date code became standardized. This was later reduced to "PAT." followed by the two-digit date code in mid-1979; e.g., "PAT.81"

PLEASE NOTE: The following photos are not representative of the safety covers used over Nuovo Record adjuster bolts. These were mandated on all NR and SR derailers after the 1978 CPSC revisions, and as seen below, were fitted on some 1977 RD's as well.

Using the Nuovo Record with larger cogs than 26 tooth

Though the Nuovo Record was rated by Campagnolo as having the ability to work with cogs with up to 26 teeth (due to the fact that the upper jockey wheel will jam against larger cogs), it is possible to push the envelope of this limit.

With the Nuovo Record derailer, the jockey wheel moves upwards towards the cogs (as the pulley cage is tensioned) until both pulleys sit on a vertical plane to each other. At this absolute vertical point, the pulley wheel will rub against any cog larger than ___ teeth.

Thing is, if additional tension is added to the pulley cage - from the point wherein both pulley wheels are vertical to each other - the upper jockey wheel will begin to move downwards with the rotating cage. This effectively lowers the upper jockey wheel away from the freewheel/cassette cogs, giving you the extra clearance necessary for the jockey wheel to slide under larger cogs.

To get the pulley cage to rotate far enough to clear, one must get the pulley cage to rotate quicker than usual. This can be achieved by removing enough links from the chain until the pulley cage rotates past the vertical plane before the derailer shifts into the first cog exceeding ___ teeth.

Many riders simply pull their rear wheel farther back in the frame's dropouts - assuming the frame is equipped with long horizontal drops - to the same effect. This works equally well, but it is important to remember that this principle is the same as shortening one's chain - instead of shortening the chain, your effective chainstay length increases.
