I think that wheel is called Scirocco. It came out around 1987-88. There were also the Ghibli (high-end, $3000+) tension disc and the cheaper heavier, Khamshin. I recall the Scirocco being 650c only. In any case it dates to a time when "all" TT bikes had small front wheels. Your Speedstream bike sounds like it is from a different era, even if it's only a few years older. Radial-laced 24 hole V-secion tubulars might be more appropriate for this bike. The early 80's were the age of relatively normal bikes that were slightly reprofiled for small areo advantages. After Moser's hour record and the '84 Olympics, discs, cowhorns, and unequal wheel sizes became the norm (for exotic TT stuff).

There is no date on the lock nut just Camp 42 SU. This is on the outside of the locknut between the serrations and the thread. The QR skewer is curved with script logo. Ends are shaped like Fez's if you get my drift. I guess it is 80's, possibly just out of time line. The disc has 4 holes in it, is pearl white with blue Campagnolo logo right across the middle. Hub is held on with 4 rivets. Disc appears to be made of a brown foam like material. Not fibreglass or carbon. Rim is sprint type. WTB a matching rear, gear thread. I have a 1983 Holdsworth built with Reynolds 531 "Speedstream" tubing. They were popular with time triallists so I hope to build a replica. I have English frames and equipment to trade for a NOS rear. Mark Stevens ( with a great holiday cottage to rent) Dingwall, Scotland
