As I posted a few weeks back, I've been looking for a couple of interesting (whatever that means to me) vintage mountain bikes to build up as path riders for my wife and myself. I was able to buy a nice Schwinn Cimarron from wrk101, and it came with delivery to Illinois, and the side benefit of a trip out to the country and a chance to meet Bill and his charming wife.

Now I may have scored bike #2 , a mid 80s Stumpjumper Sport I was able to buy from the original owner. She worked in a bike shop at the time, rode competitively, and well enough to be sponsored (!), but her original frame broke and Specialized sent her another frame, which she put the parts on. She noted replacing the original stem with a Salsa, but otherwise indicated that the bike parts were original.

She wasn't exactly sure when the frame replacement happened, but I'm guessing relatively early, as the parts kinda indicate a 1986 bike using the chart at Mombat, but the orange color also looks like 1986. Of course, no bike specs or catalogs really reflect anything hard and fast, bikes were products to get shipped, and shops often swapped things out at point of sale.

My bike does match most of this one that was on eBay a couple of years ago:

Seatpost on my bike was clean, stem a bit stiff to get moving; I haven't pulled it yet but don't feel a problem coming. Frame has quite a bit of rust on it, so this may be the first one I take in for powder coating.

Serial number is CS 625323, which doesn't quite fit into any of T-Mar's Asian mfr patterns. Frame does have a sticker stating 'Japan.'

Here's a parts list...obviously 'Specialized' was rebranded high quality parts.

BB/Crankset/chainrings: Specialized
Shifters: Shimano thumb
FD: Shimano 'Deerhead'
RD: Shimano Mountain LX (replaced?)
Freewheel: Shimano
Rear hub: Specialized
Rear rim: Saturnae X-28
Front hub: Deore XT
Front rim: Araya RM-20 with stickers from shop build
Brake levers: Dia-Compe (!)
Front brake: Shimano caliper
Rear brake: Roller-cam (Suntour I think) under chainstay--first time I've seen this short-lived fad!
Seatpost: Strong/Japan
Stem: Salsa (might have been slingshot style originally?)
Bars: Nitto, low rise, probably original

I have not done a bike project in several years, but this seems like a fun way to while away some of my winter on. Wife recently said that what she looks forward to most is doing more long day rides together next year. Now that's inspiration!

Okay, enough of my yaps, here are some snaps:
