Dating campagnolo components
Above, the so-called rod gear was actuated by a rod behind the saddle. Spence Wolf of Cupertino Bike shop offered his own long cages (above). The basic design was the same, but it featured exotic-alloy bolts and black trim.Chain slack was taken up by ratcheting the rear axle forwards or backwards in the toothed droupout. Above, left to right: Record 1963, Gran Sport 1955, Gran Sport 1952. Above (3 fotos): In 1983 Tullio Campagnolo died, and the 50th Anniversary Group was released.(Don't all cyclists have boxes and boxes of old components in their garage?)Most early Treks (1976 through about 1980) were sold as framesets.At least it would be the earliest date that the bike could have been made.Of course, all this assumes the bike has the original component.Above: C Record set, showing mechs, cranks, pedals, seat pin, etc.Some consider C Record to have been the aesthetic high-water mark for component design.
Swaps also can be made as the bike falls out of favor, or is being sold, where the higher quality components are traded for lower quality ones that the owner had onhand.
Campagnolo's racing credentials go back to the 1920s.
Known variously as Campy (in the USA), Campag (in Great Britain), or Campa (in Germany and elsewhere), their components dominated the high-end cycling market for decades. Below is a sampler of a few of their more notable components. Nothing else at the time came close to its precision and reliability. Until the advent of the Campag Rally in 1974, tourists who wanted the precision of the Campag mech required long cages to take up more chain slack. Above: the successor to Nuovo Record was Super Record, introduced in 1974, final year of production 1987.
The Record brake remained largely unchanged until it was replaced by the C Record Delta, above.
Deltas had good stopping power and excellent modulation; probably the handsomest brakes ever designed.
Deltas had disadvantages however: they were heavier than the dual-pivot designs coming out of Japan at the time, they cost as much as some frame sets, they could be used only with very low-profile tyres, and were very tricky to set up and adjust. The Record aluminum double-ring crankset with four-sided taper axle was the standard for racing machines for decades, replacing earlier steel cotter-pin designs.
