A little MTB history: While a lot of folks assume the original Stumpjumpers were modeled after Tom Ritchey’s frames, Specialized designer Tim Neenan actually based the geometry on his own Lighthouse Chaparral bike built in the late '70s. The first 250 frames were made in Japan and assembled with a mix of parts — BMX-style stems, Magura-inspired moto bars, Mafac touring cantis, Tomaselli levers, and SunTour road gearing. The first full bike dropped in 1981 for $750, weighed 29 lbs, and helped kick off the entire mountain bike movement. By 1986, MTBs were outselling everything else in bike shops across the country.
This one’s from just a few years later — still early days, possibly when Jim Merz joined the design team - and it’s the harder-to-find XL 22" frame size. The build is mostly original and era-correct, with a Suntour Mountech friction drivetrain (3x5 setup with 46/36/26 up front, 14–32t in back), Takagi Tourney XT crank, and Mafac cantilever brakes. Wheels are 26" Saturne X28 rims, and it still has the original Specialized bullmoose bar and Avocet Touring WII leather saddle with beautiful patina.
The original brake pads, cables, and even the tires were kept intentionally — still usable, and part of the charm. It’s tuned and ready to ride.
This bike’s a great fit for collectors or anyone who just appreciates that smooth, all-steel, fully rigid early MTB feel.
Fits riders roughly 5’11" to 6’2".
I collect and restore vintage bikes, and I enjoy bringing gently used more recent models back to like-new condition. It’s always rewarding to see them back on the road, helping people stay active and reduce car use. I also offer repairs and tune-ups for the bikes I sell - please check out my Instagram - sfbikemarket.
I’m a great resource if your bike was made between 1970–2015, since I have those harder -to-find parts from Shimano, SRAM, and Campagnolo 7–10 speed drivetrains, as well as appropriate and matching replacement wheels.
My tiny “one-man-orchestra” operation is on Treasure Island, SF. It’s easy to get here - Bus 25 runs every 20 minutes from the Salesforce Terminal and in 10–15 minutes drops you off a block away from my place. There’s also a $5 ferry from the Embarcadero, a fun option if you want to explore the island or visit Mersea for food and views and don’t mind walking a little.
Oaklanders and Berkelenians might need to add a Bart ride into the city first, but have the luxury of riding their newly acquired bike down the bay bridge back home.
