The first Sequoias were built in 1981, and were touring geometry with chromed Shimano dropouts and normal/long reach caliper brakes. When the Expedition came out, the Sequoia Geometry was updated to sport touring. The early Sequoias were built by 3Rensho, really, I had Tim Neenan confirm this. He designed the first Sequoia and Allez and his name is on the chainstay. Those first Sequoias are hand built beauties, and are very rare. I have seen one in recent years. They have a deeper blue paint color than the later blue Sequoias, and as mentioned, chromed dropouts. No chrome.....no 3Rensho. The decals will say Specialized on the downtube and Sequoia on the top tube.
