I only know what I have come across on forums. the 400 440 etc were in the middle of the years they were made. they started making them in 1986 if i recall correctly. ive only seen a bike though 1991 but might have been made though 1992. I have a 1990 technium prestige. they were an early aluminum bike with steel lugs bonded together with an epoxy. I've read a lot of opinions saying something to the effect that the bonding will fatigue and the frame is totaled but nothing confirming that besides anecdotes.
its a beater but it rides nice and I have fun riding it.
