Years and years ago I worked in a bike shop and Micheal a customer of the shop used to bring in his bike for various jobs, it was a Specialized Sequoia. This bike used to wind me up, it had campagnolo brakes and hubs and it just didn’t seem right id never seen one looking like this. So fast forward several years and much pestering ( we now ride together ) Micheal decided to sell me his old bike. he told me how he had bought it new in Chicago in 1981 and that it was only avaliable as a frame set and how he had it built up the way it is. It turns out that this was the first year specialized had done a frame let alone bikes . So I’m still trying to learn more about these frames and eager for any input. I’m hoping some discussion from this will help clarify things .
