I am finding information on early Specialized roadbikes is hard to find. Here is what I have found, and hopefully others will share what they know. According to Bryant Bainbridge, Director of R&D at Specialized from 1983-1990, Tim Neenan ( Lighthouse Frames) was their first frame designer. Tim Neenan designed the Expedition after a custom touring frame he made for Mike Sinyard ( Specialized owner) . I believe Neenan was also responsible for the Sequoia model. Next frame designer was Jim Merz. The mid eighties Allez bear his name. Was there an earlier Allez that was designed by someone else? The final designer of the lugged steel era was Mark Dinucci ( associated with Strawberry cycles). I believe he was responsible for the Allez Pro and Allez Comp. According the Bryant Bainbridge, 1984 production Allez were made by Miyata, later some smaller factories. From Tim Neenan: the Expedition was made of Tange tubing, the same gauge as Columbus SP- 1mm/.7mm. I find the Specialized lugged steel frames interesting because they combine the designs of talented frame designers with the craftmanship of the Japanese and later Taiwanese builders. Can anyone add to this.
