1983 Stumpjumper — Something Specialized This Way Comes
Many of our regular readers are familiar with our current Murphy’s Law Project, but we wanted to take a few minutes to let everyone know about one of our other unique projects:
Something Wicked This Way Comes is a classic fantasy / horror novel from Ray Bradbury that inspired a whole segment of popular culture, from the self-titled movie to the Stephen King masterpiece Needful Things. Likewise, we hope that this 1983 Specialized Stumpjumper can be an inspiration to mountain bikers looking for something both vintage and unique. It’s a little bit classic, a little bit more modern — much like the resto-mods of American car culture.
Basically, this bike serves as a proof of concept. At the onset, we were looking to incorporate a few unique elements all into one bike:
- Vintage lugged steel MTB frame with matching rigid fork.
- 650B wheelset with plump MTB treaded tires.
- Very modern 1 x 9 drivetrain
And along the way, we added a few other unique touches of our own:
- Metallic Copper paint
- Gold accents — shifter, derailleur, cassette, spoke nipples, etc.
- Soma Clarence handlebar (for a little more swept-back hand position)
- Cane Creek Direct Curve 5 V-brakes in place of the original cantilevers.
Obviously there is still more work to do, but we hope to have this bike out and about our local trail system right after the first of the Year. At this point it is hard to imagine letting this beautiful bike into the mud, but it is all about the experience of bringing together something old and something new.
We’ll give a full ride report once we get a few 100 miles under our 650B wheels. Until then, feel free to contact us with any technical questions or ethical dilemmas.

Did you move the canti posts to accomadate the 650b wheels,or is there enough adjustment in the cane creek brakes for them to fit?
Yup, the Cane Creek Direct Curve 5 brakes worked right out of the box.
Bryan, That bike turned out really nice. I think I would like to try the 650B out on a bike.
Wow! I am going to get a pair of those brakes for my commuter, I had been using a homebrew adaptor trick that I saw on another site,but this is a much better option.Thanks!
Any problems to report with the 650b conversion? How does it handle? The bike looks great by the way.
So far, the bike feels good. I’ve probably ridden it about 10 miles total … but I haven’t been able to give it a “proper” off-road ride — the weather just doesn’t want to cooperate long enough for the trails to thaw / dry.
I’ll give a full mud-covered report soon (hopefully).
Ride report yet? I’m getting anxious to hear how it rides. Does the tire size effect the trail?
