Too curious to wait.....very early aluminum MTB.....ADDED PICS!
I only have this picture until daylight tomorrow........it has Shimano Deore rd, fd, brakes and headset...Shimano parasomething hubs....shimano STI SHIFTERS......it is all aluminum with a steel fork (maybe replaced)......the rear chainstay brake placement puts it in the early '80s I think.......
and the dayglo green is just paint; no lugs....
I just can't pass up a quality beater............thanks for your input.........

From first glance at least in spirit, this seems to resemble the 1991 Raleigh Technium "Heat" model I bought for my wife-- though minus the full day glow fork and the pink branding. Same component system as well. Does yours have a serial number on the bottom of the BB?
Here's a pic of my wife's. It's a great bike.

it also appears that the green paint is factory applied.....? There is a serial number on the BB under the grunge; I'll post that when I can get it.
Thanks again...

Still learning
Well with the replacement fork and front wheel, unlikely the bike had a suspension fork. Wait for the chain stay brake specialist, Frantik, to weigh in.

Thanks! That's exactly what I wonder about; the fork. I'd like to know (see) what came on the bike and maybe replace it....

I'm almost certain that's a Trek, based on the "lug" work and seatstay bridge. Get the whole serial number off the BB shell and look it up on the Vintage Trek site.
Fork looks out of place.
Edit: based on Mombat's Trek history, this is either a 1987 or 1988 (U-brake on the chainstay.) Unfortunately the powdercoat diminishes any value the components could have in dating the bike, but the serial number should give you the info you need. It's either an 8000 or 8500 as those were the only two models made then.

It's either an 8000 or 8500 as those were the only two models made then.
The two big stories for 1987 were the introduction of Treks bonded aluminum technology to mountain bikes and the new Shimano Deore XT index shifting system. Trek used an un-weldable 7178 aluminum tube set bonded to a set of cast aluminum lugs. This allowed the frame to be assembled from mid-sized tubing and eliminated the stress of welding the aluminum. The idea was to obtain a more comfortable ride than the oversized frames from companies such as Klein and Cannondale while saving about 3/4 of a pound of weight. Trek offered this frame in the 8000 XT and 8000 models. The 8000 XT used the new Shimano Deore XT component group with 6 speed index shifting, Biopace chain rings and chain stay mounted U brake. The 8000 offered similar features but used the lesser Deore components. The steel framed models were made in Taiwan by Merida and featured 3 models: 800, 830 and 850. The 850 used the new Deore index shifting system on a double butted cro-moly frame with chain stay mounted U brake. The 830 used the double butted frame with a lower end Shimano index drive train and cantilevers while the 800 was a straight gauge frame with basic Suntour index drive train.
1988 starts the expansion in the number of models that really explodes in a couple of years. The bonded aluminum bikes continue with the 8500 (Deore XT) and 8000 (Deore) both with index shifting, chain stay U brakes and Biopace chain rings. The top steel bike, the 870, features a lugged True Temper frame with Deore components. The remainder of the steel line consists of the 850 (Tange tri-butted, Deore), 830 (Tange, Deore shifter, SR crank and hubs), 820 (Exage) and 800 (Shimano Light Action). All of these bikes use a chain stay mounted U brake. One interesting bike is the 900 which uses 1.25" tires and Accu Shift components, an early city bike with riser bars and stem. The Matrix branded parts are starting to show up in the rims, tires and hubs. The hubs are available in loose ball or sealed cartridge bearings. Tires are the lower end CDX (1.6" or 1.9") and more off-road oriented CDZ (available with a Kevlar bead-CDZK or with Kevlar belt-CDZR). There is only one mountain rim, the Singletrack, which is a box construction hard anodized rim (white Matrix wording with Single Track in gold over a set of white mountains). The 1988-1992 head badge is show to the right.

There is is a whopper serial number on the BB. I'll run that through the trek sight tonight. I think you're absolutely right though...1988 Trek 8500.
Thanks for your help!

My point was if the bike was powdercoated, it's doubtful the components are original. Did I notice a Deore XT headset? With otherwise Deore components? That's unusual. Also, you know the front wheel is a replacement and the fork is in question. On a bike like this I'd date it by the serial number alone.
I didn't mean anything regarding the monetary value of the bike.

A lot of Treks have "Trek" stamped on the rear dropouts, or on the seatstay caps. Dunno if the 1988s did, researching...

chainstay ubrake suggests 87/88 frame. RD is an 1989. STI shifters with cantis is early/mid 90s tech
looks a lot like this Trek 8000 https://forums.mtbr.com/vintage-retro...ed-568460.html
