Just picked this thing up for a song today from the original owner, came with the original manual, seat bag, tools, lights etc. Just wondering about the quality of the tubing, components etc., it has shimano shifters and deraileurs, but there does not appear to be a model marked on them.
The main tubes are 6013 aluminum alloy, which is about 10% stronger than the 6061 used in most frames from the era. However it cannot be welded and was glued into lugs. Tubing is slightly oversize to add rigidity compared to standard diameter aluminum frames. The forks and stays are CrMo steel. This cut costs compared to all alumiunum, and provides a traditional appearance compared to chunky, alumuinum stays.
The 4xx series was availble in three models. All used the same frame but differed in components level. The 440 was low end model, costing $250 US and those should be Shimano Z-series components. These bicycles were considered great value in their day.
I didn't think the Techniums appeared until the 1986 model year, though they would have been available in late 1985, which may explain the 1985 Owner's Manual.

the one you have does not use downtube shifters and that is a good thing as I have seen and heard that they can break at that point.

Nice pick up. You beat me to it. I was the second person who called him.
But after seeing your pictures that is OK as it is too big for me.
Glad to see it went to a local person, anyway.
Please double check the stem as it looks like it may be pulled out past the safety line.
I also picked up an 86 440 from an original owner. Similar paint scheme, but components are Suntour AR, and Sakae Ringyo.
As mentioned above, the frames were the same across the line of 440 460 and 480.
The 440 was set up as a touring bike.
Frames are made in Kent, WA. The unique lugs, and multi-step process used on the T8 aluminum tubes to improve the joints and prevent defects, made a superior 'glued' frame as compared to adhesive failures with some European aluminum bikes.
The frames are quite light for their size. IMHO, pretty well made, with nice details like internal brake routing.

Link to an older Post of Mine that shows the Technium "Build" Brochure
I have a 420, 1986. Same frame as the other Techs' although not many original Components left on mine.

Can anyone help list the specs for my 1986 Raleigh Technium 440?
I am modifying a lot on the bike and would love it if someone who had the original owner's manual or knew all the spec sizes for this bike to please post it!!!! For example, bottom bracket size, stem size, etc...

Those techniums used standard english thread bottom bracket and a quill stem with a standared 1" threaded steertube (stem measures 22.2mm). Rear dropout spacing is 126mm (6/7 speed) but could be spread wider to 130 if you want a newer hub as the rear triangle is all steel, not aluminum. Rims were 27" but can easily be changed to 700c if you want. Ditch the stem mounted shifters for some bar-ends or brifters.
About the only other compability issue I would forsee if you try to upgrade that bike is that the seat-tube is probably larger than 28.6mm, be sure the front derailler clamp is sized accordingly.
