Here's my conversion; a 1987 Schwin Cimarron. So far this year, I've clocked 1900 miles on it, and despite being heavy, it's been the best commuter I've put together so far. It's built with a slew of fun parts that were on my previous mountain bikes; while it may look lke grandma's bike, closer inspection tells the story.

What rear rack is that? Looks like it would handle a gorilla sitting on it and not bend!

^^ The rack is a Surly. No question that it's bomb proof; it weighs a ton, but I really liked the adjustability.^^

Great Cimmaron, bconneraz! Very rugged beast, and I like those centerstands. They can hold up any loaded bike.
+1 on Frantik being positive over the DT braze ons. It's a rarely seen mod, but a cool one. The Stumpy frame looks fantastic and I can't wait to see the finished results as well.

The stock gold metal flake color on mine is called "Sunset Orange"

Shoot! A quick check of MOMBAT's Specialized spec chart identified the standard and team model Stumpjumper as being double butted Tange Prestige but was not specific beyond "Cro-Mo DB" tubing. Maybe it's Ishiwata like mine, our bike definitely have the heftiness in common! The Nashbar catalog states the weight is 28 lbs for a 21" frame. Both frames came with "Deerhead" XT components but I notice that the Stumpy came with a 5 speed freewheel, the Terra XT came with a Sun Tour Winner 6 speed freewheel. That proves the flexibility of those friction shifters, I've run them on 5, 6, and 7 speed set ups. By the way, SimiChrome from Germany really does a nice job on the XT components.
Here are a couple detail shots, one you can see the paint color a little better in the sunlight.

Bill started this thread 104 pages ago and has done some fabulous conversion. My favorite being his "skinny" Cimarron, I love it because he was able to get his Cimarron down to 25 pounds and I couldn't get any of mine under 26... that damn magical pound elluded me on two different builds ('85 and '88 LE). Do you make the ride from the canyon to the sand? I live in North O.C. and frequent The Fullerton Loop and Carbon Canyon, I don't make it down your way often these days but I sure do love and enjoy the trails that surround you!

Retro Tan Gumwall modifications - Mongoose
Updated the build for a retro look and hitting technical trails. Added to build as follows:
-Picked up a second set of Vuelta wheels ($65, last pair from Wheel and Sprocket outlet)
-New Duro Rocky Wolf Tan Gumwalls (ebay - $12 each plus shipping)
-Sram 8 speed 11-30 freewheel ($22 - bikewagon)
Also, gave up on my re-cover of the old Vetta. The vynyl I used cut too easily. Just went with a Brooks B-17 Honey.
Yes, it's a heavy S.O.B. but I love it.

Indeed they are. But not terribly so. What doesn't kill you only makes you stronger!

Great inspiration. We should start a Cimarron thread!! I tried to snag another one, but missed out. All the bikes I have, and my $15 Cimarron is my favorite.
Its one of Schwinn's sleeper vintage bikes.
Good excuse for me to post my latest iteration of the Cimarron. I swapped out rear racks with a nice one I picked up at the Habitat for Humanity store. Handles my vintage Madden panniers quite well. The rack is pretty nice, its modular (three pieces), so really adjustable for fit. No idea who made it. Similar in shape to your tubular rack, but it has an extruded aluminum deck.

And Frantik- just keep an eye on ebay; they either pop up for crazy cheap (I should have bought the last frame and fork I saw for 75 bucks a month or so ago) or they are crazy expensive. They are indeed gems.
