Normal 0 false false false EN-US X-NONE X-NONE 1995 First 6069 Custom Specialized Mountain Bike. Rock Shox, Shimano, Grip Shifts, Mavic Rims, Velociraptor Tires, Bontrager Seat. In the 1990s, I was involved in a research project to develop an aluminum alloy stronger than 6061. It was a joint project between Northwest Aluminum, SAPA (now Hydro Aluminum), Oregon State University and Specialized. Numerous alloy combinations were tested before arriving at a final alloy addition combination including silicon, magnesium, copper, iron and vanadium. We then applied for a patent and asked the Aluminum Association of we could register the alloy with the 6069 number designation. Both were granted (you can google the patent if you wish) and Specialized built the first bike out of 6069 tubing. That is this bike! Specialized went on to build a lot of bikes out of this alloy and had exclusive use of it for a while. But it didnt take long for other bike manufacturers outside the US to start using the alloy, sidestepping the patent. When the patent ran out after 14 years, a lot of other bike companies start using 6069 and today it is on wide usage.Sold as is with no returns. US sale only. Will consider shipping it if the buyer is willing to pay the cost (to be determined). Thanks for your interest.
