Anyway, as mentioned above, this is very small for me and will be ridden very little if at all. Going to clean it up some more, have some actual experts evaluate, happily add it to the collection and drool over it much much more, as I said, no danger of anything catastrophic happening. After a lifetime of mechanics and 35+ years drag racing motorcycles, I have a pretty good handle on potential failures, even when they happen at 125 mph in a 1/1000th of a second.

Tx, and for your opinion, going to assume you are an expert frame builder, being able to say with such certainty how this will go from a few pics, I doubt that anybody is that good. Not saying you 're wrong just saying that's quite a leap.

I hope you get a good finding on it. Edit to add, it sounds like you have some good materials experience, you are there to see it up close. What NDI has been done, how did you determine it still to be structurally sound? It is your judgement and I defer to it given your experience. We talk about opinions, but, really, opinion can be largely removed and it is facts I prefer to deal with. But I realize, most do not have facilities for that level of investigation, leaving us with judgement and opinion, which can be good if the opinion is based on real experience, like yours.

No, I am an engineer and a mechanic, A&P, IA with inspection credentials and NDI credentials. I do this stuff for a living, for real where lives are at risk if I am wrong. So, I am an actual expert. But, casual photographs like these are difficult to be sure.
I hope you get a good opinion on it.

Again, this will never be a rider for me, but it may get fixed or it may just sit on display. I will have Jim weigh in and Dave Levy of TiCycles will but his eyeball on it as well.
Tx again.

Update:
Sadly, my friend has passed away, but I will think of him whenever I ride, or work on this bike.
He left me a box of parts that I though may have contained the original Campy MTB group set, but unfortunately, those are long gone.
So, I'm going to leave the IGH in it, but I swapped in a few other parts I had laying around to try to balance the trim colours a bit, and to make it a little more rideable.
Took it out for a little jaunt this afternoon, and it actually rides quite nice. Much better than it did with the handlebar jacked way up, and that huge saddle that was on it.
By changing the chain ring, I lucked into a magic ratio that enabled me to eliminate the tensioner. I must be the luckey one, because I have 3 IGH bikes with vertical dropouts that I'm able to run without tensioners.

Having working in shops, there is nothing sadder than inheriting a bike this way....

Almost spot-on, ‘91 Rockhopper Sport. Only the wheels are original at this point, and are up for replacement due to rim wear. It’s obviously on the small side for me, handed down from my father. The small size actually works well on the rougher trail sections. The Thomson post was the only one I could find in 27.2 with enough extension to work for me.

Well I appreciate that and I as well have some professional qualifications, ASE Master and FoMoCo Senior Master Technician for 35 years so I have had plenty of people's safety at stake also. And as I said, a lot of time at the dragstrip, so I've seen a fair amount of this in practice with plenty of extreme force and speed at play.

That said, that's a lot of paint to leave the frame. Imron?

I saw the same stuff. BITD (80s-90s) we found that the good thin wall tubes were more resilient than the paint. Road frames built with crazy light tubes (.7/.4/.7 and lighter) could crack the paint in normal use around the lugs without doing any damage to the frame. Any crack in that frame is probably going to start at the point of that lug and would be obvious in the bare steel.
That said, that's a lot of paint to leave the frame. Imron?

Yep, should be Imron, not sure if Virginia was still painting them, but still should have been Imron and they were zinc chromate dipped beforhand.

Memorial day update, started out by swapping in some bullmoose bars, derusted, cleaned and polished the Suntour Mighty thumbies, Magura levers and installed some Oury grips. This changed the front brake cable access so out came the NOS Mafac tandem canti's that were procured for this or a Stumpy project to solve the cable issue quickly and easily for the time being. Swapped in a black Brooks and standard Record seatpost for good measure as well.
I now have a quandary with the wheels, it has the wheels that it came to me with that are mismatched but have the cool Black Bullseye's that will be built up with matching good rims later.
For the near future I have a set of UKAI with Suntour XC hubs or Araya with "sealed bearing" hubs. Lets have a vote.

I love, love, love my Specialized Rockhopper. It's rides so beautifully, both on and off road. I finally swapped out the original tires for the far more versatile set of 26 X 2.30 Kenda K-Rads. I was a little worried that they would fit, but it turns out that there's still a ton of room left. I might have even been able to fit the 26 X 2.5's.

I sold my '92 Diamondback Apex a couple of years ago. Still had the original DX components (except for one of the shifters) I bought it new in the 90's and rode the heck out of it on the trails of Central PA. I don't hit those trails anymore, stick to gravel now, but this thread is making me miss it
