If memory serves, the USA Technii were made between '87 and '93 at the plant in Kent, WA, just south of Seattle. Raleigh needed Boeing's expertise in bonding dissimilar metals and so decided to settle nearby.

I don't have a current Technium but I have flipped a boatload. Love 'em. Ride is very smooth for the era on most. And no, I haven't ever seen one come apart.
