1997 models online
30 Years & Soaring. Introduced in 1987, the Roc was among the first discs to give players unprecedented control and distance. This legendary bird remains a classic and, as illustrated in the commemorative stamp, soars high above the rest. We’ve stamped a limited quantity of San Marino Rocs in our Luster Champion plastic. They’re majestic, in flight and on the wall.

"The first Roc came out about '85. It was a small diameter 21.2 cm diameter disc based off the XD. In '87 that disc was replaced with the first version of what we consider a Roc today-the 21.7 cm diameter San Marino Roc. This disc quickly became the most popular disc on the market. At the time the Stingray was about as long a disc as you could get, so the Roc was used by many players for almost every shot.
In '94 or '95, something happened to the Roc mold and the disc was replaced with a new version. Innova's mailing address had changed, so the tooling on the new disc said "Ontario." Thus the old disc became the "San Marino" or "Sanny" Roc and the new disc was called the "Ontario" Roc. The Ontario Roc has a higher dome and flips easier than the San Marino's. Because of this they were not very popular and they were replaced in 1997 by the current "Rancho" Roc, so named because Innova moved from Ontario to Rancho Cucamonga and the tooling once again changed. The Rancho Roc is the most overstable Roc yet, and has been hugely popular.
So, there are really only three molds: San Marino, Ontario and Rancho. If you go to the store and buy a DX Roc or a KC Pro Roc, it is a Rancho mold. From most overstable to least overstable they go Rancho-San Marino-Ontario."
