To rebuild or discard?

Hi all,
I have a '90 Stumpjumper Comp frame and SOME parts that have occupied a
prominent place in my storage closet for almost 8 years after I had the
frame repainted.
I was going to get at it 'someday'.
I loved riding that frame, maybe because it was really more like a road
bike with off-road componentry (hardtail, hard 'nose', 7-speed XT, 1"
threaded headset) and I'd love to ride it again.
Is it worth rebuilding (I hate to throw it away)?

No, it's not worth rebuilding. You'd be lucky to find an idiot willing
to give you ten bucks and haul it all away..... when I come over and
get it? 🙂

(I must add that I no longer have the crankset and BB).
I'm wondering about a number of things:
Since I need to buy a new crankset, will a 9-speed crank/rings work with
my 7-speed hubs/cassette?

Yes.

Quoted message said:

What size BB would I need?

This is determined by the cranks.

If I discover I'd like to upgrade to an 8- or 9-speed wheel/cassette,
would current 9-speed wheels/hubs fit between the dropouts of that
(7-speed) Cro-Moly frame, both rear and front (I want to continue to use
the original fork)?

It will fit, but it *may* require spreading the frame. I had a
7-speed/LX Trek from a few years later that had 135mm OLD in back, but
I'm not certain when the 7-speeds went to 135 on MTB. Spreading a
steel frame is a simple matter.

Will my old 7-speed XT rear derailleur work with a 9-speed cassette,
given that I'd be using my old-school, bar-top, thumb shifters?

The derailleur will work, but the shifters won't. You are better off
sticking with 7-speed for now. Or maybe 8. Some (all?) XT 7-speed
shifters had an extra click.

Those XT thumb shifters are a prized piece of gear by some people. If
you don't put them to use, there are people out there who will.

Am I insane for considering such a project?

Hmmmm.... a freshly painted classic bike that needs maybe $100 to get
back on the trails, a bike that you loved? You'd be crazy *not* to
ride it again!

Thanks all.

Thomps.

No! Go for it. It may be 14 years old, but I'm sure you will still get
plenty of enjoyment out of the bike. As long as it does'nt cost to much, it
would be a nice project. Consider it a classic and your restoring it to
enjoy. Good luck and happy biking.
PS: I wish I had an older bike laying around. I'd love to have a go at such
a project.

If all you need is the BB and cranks, it would be worth it. If you
need to replace much more, it may not be cost effective. Of course,
there are lots of people who restore old cars and more without concern
for the cost. They have an emotional attachment to the item.

You can still find 7/8 speed cranks. One of the Sugino cranks may be
a good match to all your other "vintage" parts. I would keep it 7
speed, especially if the rest of the drivetrain is fine.

In my opinion, yes.

Yes.

Quoted message said:

One with an overall length to match the cranks, and a shell length to
match the frame. In other words, until you know which cranks you'll
be using, this question can't be answered.

I don't recall whether the Stumpjumper used a cassette or freewheel,
but if it's a cassette, yes, the 8/9 wheels will fit with no problem.
In fact, it's often possible to modify a 7-speed cassette freehub to
accept an 8 or 9-speed cassette. (I just did one of those myself.
Five minutes of *careful* grinder work was all it took.)

Yes, assuming that the shifters are friction and not indexed.

The possible answers here are so many, but I'll just give one...

Insanity is all in the mind; why worry about it?

There's no need for it. I have an 1986 "stumpjumper sport" a bit heavy, but
still a lot of fun. It is 135 mm OLD.

The derailleur will work,

Depends on size of the largest cog. Perhaps it will not work with anything
larger than 30T. My old XT with "stag head" works with 30T max.

I agree with all the responses. Keep it.

I rode a '91ish StmpJmpr for a good long while before giving it to my
now x-wife. I noticed it had rusted up a bit on a past visit and took
it away from her, had it powdercoated, put some of my old 9speed gear
on it, and a suspension fork against my better (?) judgement, I don't
think it does much for the handling.

I was torn on giving it back after the rebuild, and happened to find a
NOS SJ comp on e-bay. It's powdercoated in the same color so I could
utilize her rigid fork. Looks great, has an Eric's Eccentric from
White Industries, running fixed and free singlespeed, suspension stem
and scorcher bars. Alot of fun. Hope you'll enjoy yours again.
