Discerning value of 1988 Trek 870

I know that many of the older Trek models are valuable, it seems the 870 in red was only made in 1988. I cannot decipher wether this makes this a more valuble bike or not.
anyone know the tubeset on these?
I think it may be my size but I'm more interested in resale value as I have too many bikes to hold onto more.
also it's only $35 which seems like a hell of a deal on any 80s trek.
thanks!
only pic avaible

Found some info on tube set. Still curious about current value.
looks like largest size was a 22.5" so it's no good to me as I need at least a 23" and that's the low end.
no 870s on Ebay to compare prices too.

It is worth more than $35, especially if the frame is crash damage free.

Not a lot more. And not in that condition. If it doesn't need much, and is sound it's a good around town bike.

I passed on an 820 in similar condition the other day for less money.

Funny, somebody did buy all three bikes I passed on. There is a never ending supply of people ready to buy junk.

I'd get is for $35 - I don't think these pop up a lot.
Since you're not interested can you let me know where this bike might be? For $35 I may be interested.
Thanks.

This could be a decent bike, but I suspect it might be one of the early MTB's that were way overbuilt and heavy as tanks. I had a Gary Fisher MTB, a "Celerity" that was like this, a $600 bike that weighed 30+ lbs, it was a Tru Temper frame, but probably not their lightest stuff.

Frame aside though, the parts alone are easily worth $35, if you have room for them.

certainly!
it's on letgo in the portland area Right here.
they only made it in this color one year so I doubt they show up much.
If it were my size I would go for it but they only made it up to a 58 cm.
I really shouldn't be buying smaller than a 60 (even though I sometimes do).

Catalouge says chromally frame but doesn't list weight. That may be a sign haha
I pondered that but I'm not really ino vintage mtbs so the parts would go to waste.

are you in pdx? You should post some pics if you end up getting it. I'm curious how it rides and what it weighs.

No, I'm in PA and upon further inspection it wouldn't be worth the hassle to get it here. If it were in Portland, Maine, perhaps, as I get up that way from time to time.

Tru Temper made some excellent frames. I have an 89 660, and had a multi trak 750 and neither are/were real heavy. I am still angry with myself for letting that perfect 750 go. And it sold for good money.

As I said earlier in the thread people love to buy junk. I have seen the bike several times over the years. It's not rare. It's not a bad bike.

Well, you can have my 730 Multitrack frame, I hated that thing, could never get comfortable on it, terrible geometry, and the reinforced fork weighs a ton.

If I could get a lighter fork I might ride it again just for the tire clearance, but I found the frame to be both ridiculously short in height, and ridiculously long in the top tube. Could be the result of using drop bars though, the bike came with flats.

Cleaned and tuned up, I'd expect to see the 870 to sell between $100-150 locally.

If 23" is your road bike size, this 22.5" mountain bike should fit. Mountain bikes are usually sized a little smaller.

The 730 is a very different bike from the 750. Again, Tru Temper made many great frames. That particular 730 I have had in my hands and it is not very good. And yes, it is heavy. Different years can be very different. As you well know.
The 520 was to big or I would still have it.

rode a 970 frame for years-- if they are free of dings and road rash, all lugged steel Trek frames are great platforms for builds. With XT components and the original Matrix rims in good shape, it's worth a few hundred bucks. $35 could be awesome but be prepared that it's junk. Not a lot of capital to risk; could be nice upsides. Great riding bike and pretty bulletproof.

Not the case at all with Trek MTB. The first two year models 1983 and 1984 have some value. Beyond that they are just another rigid frame MTB.

Not the Multi Trak 750 with the True Temper Frame.

Multi Track 750 was a hybrid as I recall.

It also shared frame geometry with the 520 tourer. It depends on years.
I have had both bikes. The 520 I had was to big, and the 750 was mint, and my size and like a dope I sold it.

For lugged construction afficionatos, Treks can be desireable. They had nice lugged steel MTBs up til 1994, IIRC.

Fork looks a little raw and rusty in the pic. I'd say about $100-$250 depending on actual condition, how well it shifts, etc. From the pic I'd guess near the low end of that range as it sits. What's up with that toe clip wedged into the pedal???

Yeah I'm seeing about that for this generation of treks in the area. It is still collecting dust on letgo thoug so I'm thinking I'll pass, if it isnt getting snatched up for 35, who knows how long I'd be waiting to try and get 100.
I saw that! I just dont know. Let go is weird. My LBS says offer up is the sketchy cousin of craigslist, I'm thinking that makes letgo the twice removed cousin who shows up drunk at a funeral haha
