Stumpjumper replacement fork
 

I recently purchased a 1984 Stumpjumper frame off of craigslist. The frame did not come with a fork. No problem I thought, I've got a nice chrome biplane fork just perfect for this at home. Get home grab the fork and nope, about an inch too short. That's OK, I think I've got a nice lugged fork off a MB-3 in storage. Go grab it and no even shorter.

So my question is if anyone here knows a good resource for lugged 26 in forks with threaded 1 in steerer tubes and canti posts?

Check out Soma.

Doesn't look like the Soma options include a lugged mtb.

Lugged is going to be the hard part. Seems like most mtb rigid forks are unicrown, unfortunately.

I would put a wtb ad on CL. Maybe somebody has one collecting dust from a suspension fork "upgrade."

You could also try the 'for trade' thread here; maybe offer your shorter one in exchange. Stranger things have happened.

Lugged? A few show up on the big auction site from time to time. Tons of non-lugged ones there for cheap, also.

I happen to have one sitting around, although with a 150mm steer tube, it's probably way too short for you.

The head tube is 175mm so even the used market is going to be tough.
Just figured I'd ask here before ordering a sunlight unicrown. My dedication to aesthetics is second to my desire to ride it.
Thanks for the responses guys.

Nova Cycle supply has the biplane looking fork crowns that may be close in looks . for a custom Fork build.

I managed to find a Chromed sloping crown Tange fork 25 years ago , that I am using now in my Stump jumper sport.

One option is to consider suspension fork. I found one on CL after years of looking. Opps THREADED.... Never mind. Tall head tubes make it hard to find forks with a steerer that is long enough, even for threadless.

So keep looking, you may find one. See this thread capturing my experience, start with post #86 .

84 precedes suspension forks they would be raising the head tube Up and altering the HTA as a Result.

I wanted a 26 in. lugged mtb fork too, and just had to troll ebay until the opportunity presented itself. Usually there is no detail and it's a leap of faith in terms of steerer length, crown race size, etc. I also had to extend the keyed slot on the one I bought to make it work (luckily have a friend with a mill). There's also the possibility of grabbing a whole bike off CL...if one pops up with lugs on it.

Don,
Smirking here as I'm sort of in the same situation. My Stumpjumper as acquired came with a 26" fork but a really weird one. Obviously was changed out at some time. Neat looking bi-plane crown but cheaper stamped fork ends and NO cantilever bosses. It had a side pull brake caliper with typical center pivot mount. You're welcome to this fork for free.

Actually, prior I've offered the entire bike for a nominal amount to even free...LOL.
No takers so I changed my mind and decided to keep as a Winter rider, loaner, etc.. I'm calling it the Specialized Chainbreaker.

In continuation, I decided against brazing canti bosses for the above and in place acquired a NOS but a chrome fork with brake bosses. Its stamped 'Spinner'. Big beefy and beautiful. Cast crown, quality throughout, heavier duty ends, nicely done bosses. Problem is, I don't have a clue what thread it uses. I took it to a LBS and sorted through all their drawers of new and old headstock parts. No such luck. One of these days I'll have to take it to another, but for now the bike remains apart.

I guess the nice thing is you can always keep an eye out for something that'll look good on there.

Although it's still a unicrown, I have a soft spot for the lugged unicrown forks. I think the thought was that the regular welding wouldn't be strong enough for a fork, so they devised a lug that was brazed to the end of the steerer and then the bent fork legs were brazed into. It was just for that 1986/87 timeframe- Like roller cams...

Sorry I don't have a decent pic.

But the Biplane forks are a thing of beauty.

Yeah I was pretty bummed my biplane didn't fit.
As for lugged unicrown forks, while they do look nice I'd be scouring the internet just as hard so I might as well aim high.
I'll just but a new unicrown and keep an eye out.

I have a 1983 (I think) Stumpjumper Sport frame and fork, but the frame has a crack in it. So really, all I have is the fork. Funny how the universe keeps things in balance, eh?
