    Dumpster Find: Specialized Stumpjumper -- How To Rebuild?

    I'm out behind a shopping center looking for a few cardboard boxes when I spot a pile of four bike frames, obviously discarded. Three of the four are department store junk brands, but one is a Specialized Stumpjumper. I grabbed that one. I'm guessing it's about 1985 vintage.

    A few questions since I know nothing about these. I'd like to bring it back to life as a commuter.

    - The frame measures about 20 or 21 inches from BB to where the top tube meets the seat tube. I'm 5'-10", is this too small for me?

    - In the front there's a triple 26/36/46 with a Suntour derailleur. What modern rear derailleur and cassette/freewheel can I use? How about a SS hub with an idler pulley? The frame has vertical dropouts.

    - I'm confused about the wheel size. It only measures 12 inches from the end of the fork to the brake pads. Did these use 24 inch wheels?

    I know I have a nice frame here so any help to get it on the road again will be appreciated !

    Thanks, Jim

    a heavy old steel Frankenbike Gitane, a cruiser (not something I'd buy for myself, but it was a gift, what can you do?), a Greg Lemond, a Specialized Stumpjumper(old, steel, fully rigid), and a Specialized Safire

    Well I'm not sure about most of your questions, but nice find! A 20" frame sounds like about the right size for you. My stumpjumper is about ten years younger than yours, but I can tell you that mine came with 7sp indexed shifting and cantilever brakes (and 26" wheels, FWIW). Did yours have the triangular handlebars on it? I think that's what it might have come with originally. I have also seen one stumpjumper that was converted to a SS before, with a chain tensioner. It looks pretty slick.

    The rim diameter of 26" MTB wheels is nominally 559 mm, which is about 22." So -called "24 inch wheels" are even smaller. You probably have 26" (decimal, not to be confused with 26 x 1 3/8 or other fractional sizes) wheels.

    Sounds like a good score, check out the forum at retrobike.co.uk for some inspiration, they have plenty of images of single-speeded early Specialized bikes.

    That's an outstanding find. As was stated, a 20-21" frame is either the correct size for you or too large, but certainly not too small. A 21" frame is considere extra large. As was stated, that bike only used standard MTB 26 inch wheels.
    The vintage Stumpys have something of a cult following and sell for way more than a typical rigid fork steel MTB. It's not uncommon to hear prices in the $200+ catagory for a nice original example. While yours may not command that kind of money, it's still a great find and worth putting some money into. Good luck with it.

    Thanks, this is helpful info esp. the 26-in wheels. Yup, it has the triangle bars. It also has a lugged frame. The rear der is trashed but the front der and crankset look good. I think a set of 26-in wheels, a SS hub with a chain tensioner, a set of brake cables and she's ready for commuting duty...

    ^or it didn't happen.^
    - Solo Attack: When you attack, let the sprint group lead you out. You take no points. But when they sit up, you put your head down and hold threshold. Remember: When you see Jesus you are still about 2 minutes from blacking out. Hang on.

    By popular demand, here's a photo of the discarded Stumpjumper.

    Oh, and one more question I forgot to ask: what size seat posts do these take?

    What a great find!! I love those old stumpjumpers, and yours looks to be in great shape despite the missing parts. I always had one of those frames in mind when I was thinking of putting together an "all terrain" touring bike. If I were you I think I'd put slicks, drops, bar-end shifters and a brown brooks B-17 saddle on it. It would look stunning.

    cool find.
    why is it all I find in the trash, or at yard sales are Murray or Huffy wally world bikes?
    I'm beginning to think I need a mountain bike, and something like that would be
    right up my alley.

    +1 I'm doing the above with a 1987 Trek Antelope (not nearly as nice a bike as the StumpJumper). I've got a few parts to go but I'm liking how it rides right now. Sakae randonneur bars, 1" quill stem adapter (more stem options in my mind - wouldn't do this on my road bikes), Suntour bar end shifters, Shimano aero brake levers. The nice thing is I'll be able to switch between my knobby mtb tires and slicks depending on where I want to go. The kids are excited because we'll load it up with camping gear next summer and head up into the hills around our place.
