Well, it was worth asking. It turns out I had never actually seen a Spence Wolfe conversion before. But seeing the photos posted by several members, it is obvious that one cannot confuse a Spence Wolfe conversion with a factory-produced Rally, as the Spence cage plates look obviously homemade, or at least small shop-made. The only Rallys I had previously seen, including the one I own, have essentially the same cage as a factory Campy Rally, although the face plate is somtimes marked Nuovo Record.

Now, it is still posible the ones with Rally cage plate were homebrews, using Rally plates to modify an NR. After all, one of the big advantages of Campy stuff In The Day was that small parts were readily available, so it would not have been difficult to obtain Rally cage plate to modify an NR RD. But the motivation for such Rally-era conversions would have been different from Spence Wolfe's. Spence or his customers obviously needed a wide range touring RD, and were not satisfied with the Huret Allvit or other wide range RD's then available, or were simply fans of Campy. So Spence improvised a product to meet a need the commercial products were not meeting. But the NR long cage conversions done after the Campy Rally was available would probably have been to save money by buying only the cage plates to modify an NR one already owned, rather than buying a whole new Campy Rally. After all, In The Day, Campy NR and Rally RD's were considered quite expensive, more than double the price of most competitors.

I agree with Mike's assessment of the shifting of the "Japanese looking" Rally as being excellent, and I suspect it was far superior to the Rally that was basically a long cage NR, whether factory-produced of homemade.

However, I do not believe the "Japanese looking" Rally was actually a Slant Parallelogram, but what I have usually called a Horizonal Parallelogram. It does look somewhat like a SunTour, in that rather than the long dimension of the parallelogram plates pointing down, as in the classic Drop Parallelogram, like Campy NR, the plates instead point forward, roughly parallel to the chainstays. But the SunTour RD's added an important additional feature the Rally lacked. Although pointed forward, the Rally parallelogram plates still lie in a vertical plane. But the plates of a SunTour "slant" inward. That is, their top edges are closer to the FW than their botton edges. As a result, as the parallelogram plates of a SunTour, and the jockey cage attached to their forward end, move inward, they also move downward at the same time. This maintains a more nearly constant distance between the upper jockey wheel and the FW cogs than with a Drop Parallelogram or even a Horizonal Parallelogram. This is the genius of the SunTour Slant Parallelogram, and I think the basis of the SunTour patent. I don't know if SunTour actually invented the Horizonal Parallelogram, but they certainly invented the Slant Parallelogram, or at least the Patent Office was satisfied of that. Now even the Horizonal Parallelogram like Rally shifts significantly better than a Drop Parallelogram, and it seems pretty clear Campy designed the Rally to capture this advantage, while still avoiding the SunTour patent. At about the same time Shimano introduced the Crane and Titlist, again Horizonal Parallelograms like Rally, but not true Slant Paralllelograms, which would have violated the Sun Tour patent. Considerably later, Simplex introduced Horizonal Parallelogram RD's including the SLJ 6600. I don't know if SunTour ever tried to assert that even the Horizonal Parallelograms violated their patents, or if they ever sued Campy or Shimano over this issue. I think there is at least one attorney on the list with some knowledge of patent law, so maybe he can comment on the history of such litigation, if any.

Although they lacked the "Slant" of the Slant Parallelogram, the Rally/Crane/SLJ 6600 may have shifted as well because they all had a feature SunTour lacked - the Simplex-type spring-loaded upper pivot. It is interesting to note that since the SunTour patent expired, I think in the mid or late 80's, virtually all newly introduced road bike RD's have combined both the SunTour Slant Parallelogram and the Simplex sprung upper pivot.

One thing that still puzzles me is why, after making a major improvement with the original Rally, Campy would retrogress with the NR-type Rally that Mike refers to as the Rally Sport. While I haven't actually used this NR type Rally Sport, it seems near impossible it could shift as well a the original Rally. So why the Rally Sport? Was it cheaper? Did Campy continue to sell the Horizonal parallelogram Rally after the Rally Sport was introduced? Did Suntour in fact sue Campy over the original Rally? If so, did they sue Shimano over the Crane, which was basically the same design?

Finally, anyone have detailed photos showing the difference between what were evidently the first and second generation Rallys, the difference reportedly being mostly beefing up the upper body between the upper pivot bolt and the parallelogram, where first generation Rallys sometimes broke. I personally had a Rally break in half at this point, but this was sort of a freak event when the chain dropped while shifting to the inner ring of a triple, and jammed between the inner ring and the BB shell. The violent impact on the RD snapped it in half, but I can't really balme this on poor RD design. I would like to confirm, however, whether this was a first or second gemeration Rally. If it was a first generation I broke, perhaps the second generation might have survived the incident.
