Raleigh Technium?
This was a weird find. 80's (90's?) Raleigh Technium, found at curb, Alcoa aluminum frame, maybe the first primitive attempt at aluminum, before they made the frame tubes wider????
Let's hear it. Nice looking bike. White, blue decals. Cable housings through the frame. Oh, how aero is that. Sigh.
Pretty light, I know nothing... What wheels work well on this? Mine is 20".
I am building it back tonight.. Hmmm.

I still have a Raleigh Technium 450 I bought in 1989. It is a bonded aluminum tube frame, with a 6 speed Shimano SIS index shifting triple chainwheel set up.
It was and is a nice bike.
Mine is blue. It still has 27" tires and wheels. I have it on my trainer.

I loved mine. This pic is when I brought it home from a garage sale. Spent $40. Swapped out some parts with spares I already had and it was a fine commuter bike. I kept the 27" wheels on there but the brakes had enough reach to use 700C if I wanted to.

I picked up garage sale find Raleigh Technium 420 ($15) that looks exactly like urban_assault's.
Seat stays, chain stays, maybe seat tube, fork and head tube are steel. Other tubes are aluminum that is thermally bonded or something like that.
On mine, Weinman rims, front hub cups and cones pitted badly, so needed replacement. It has 27" wheels. You can actually fit 700's on it due to long reach brakes, but rear triangle spacing is narrow for modern hubs. You have to persuade it to fit the wheel in.
I haven't fixed mine up yet, but have taken for a few short rides. I think the frame feels kind of flexible when you pedal hard, but the ride is nice. Freewheel is friggin loud even after lube. Old suntour stuff. I think the deraileurs are Suntour alpha 3000.

400
Mine is a 400.
Sugino VP Crankset
Shimano "light action" RD
crappy plastic pedals (I hate that)
Shimano SIS shifters (which I'm not sure about, look cheesy)
Interesting note about the rear triangle/wheel issue. Thanks , I"m still dealing with the wheel thing.
What year might this 400 be?

My 420 is now a single speed.
Raleigh grabbed a bunch of Boeing engineers to make this frame in Washington State in the late 80s.
Your 400 is newer - I'd guess somewhere between '89 and '91.

cable routing
Okayyyy,
having issues with the brake cable routing to the rear brake and how it loops around the handlebars, then goes into the frame. I am terrified of attempting to put in a new housing because I have to feed it through the frame. How do you replace? attach the new cable to the old one and drag it through?
I noticed in the red Technium pic, it looks like the rear brake was upgraded, and that cable has to cross over to the right side. I almost upgraded the rear brake as well, to a better grade Dia-compe with quick release, but ended up leaving it alone because the cable housing over the rear stays was looking a little stupid. So for the rear ideally you need a leftie sidepull. Sigh.
