|1988 Specialized Stumpjumper in size 21.5 inches, as found in a dumpster.|
I've fished many a bike out of dumpsters over the years. I don't generally go looking for them, but they often have a way of finding me. Some have been complete basket cases and others have only needed air in the tires. Yet, what never fails to amaze me is finding a decent quality bike tossed in the trash. Old bikes aren't like old computers, in that they never become completely obsolete or unusable. Old bikes aren't like old cars, in that they don't degenerate into egregious polluting money pits, but instead are cheap and easy to recondition. Old bikes aren't like old furniture or mattresses, in that they don't absorb unappealing substances from previous owners.
I can understand rationalizing the discarding of a less than functional department store bike that was never engineered to work well in the first place. That which is nearly useless readily becomes useless. However, bikes that were at least initially high in quality of materials and construction, unless mangled, are almost always repairable into good running condition. This goes doubly so for steel mountain bikes from the off road boom era of the 1980s; with sturdy tubing, user serviceable components, and lack of suspension, they're almost indestructible.
Don't get me wrong. I don't pine for the old days and I'm no longer the Luddite I once was concerning the evolution of bike design. I appreciate lugs and fancy steel, but I also know that great advances have been made in materials and technology, and that, venerable as they are, these sturdy old steel bikes are no match off road for something more modern, like my Salsa Horsethief for example.
On the other hand, I'm certain that with proper care the long-term viability of an old steel monolith will far outpace many modern bikes in the utility department, most likely to the tune of decades. There are far fewer things to go wrong with these old bikes as compared to newer bikes, and equivalent parts are still readily available. With components in good order, a set of lights, a pair of fenders, and some method to carry cargo, an old steel mountain bike can't be outmatched for usefulness.

|That's a solid forged aluminum stem. They don't make 'em like that any more. The stem alone probably weighs more than a modern carbon frame.|
The drivetrain and brakes are Shimano Deore, from back in the days when Deore was on the penultimate tier of Shimano's off road lineup. The cranks are in good shape, and the teeth of the very '80s Biopace chainrings look healthy. Bearings haven't fared as well, as the bottom bracket is indexed, and the headset is in poor adjustment. However, the open seat tube is not rusted, and the chain is oily and moves freely. The derailleurs look fine and move well, but the cables and housing are sluggish and gummy. The shifters are intact, though the mount for the left shifter is bent. The good thing is that all the components on this bike are rebuildable, and the bearings are easily replaceable if needed.
There are a few additions to the bike that have occurred over the years. Though now badly bent, a period concurrent, white Blackburn Mountain Rack was a common addition to many bikes of the era. There is evidence of bar ends once installed but now gone, a sign of an update in the early to mid '90s when bar ends enjoyed popularity. A cycle computer mount at the rear wheel, indicates this bike was probably used on a stationary trainer at some point. Bright red paint under the upper and lower Zefal plastic pump mounts along the back of the seat tube signal that they were probably installed at or near the time of purchase.

This Stumpjumper is readily identifiable as being an '88, due to its under the chainstay u-brake, a feature adopted by most manufacturers for a brief period spanning from about 1986 to 1988. Builders and riders went crazy for u-brakes because of the clean looking cable lines and the u-brake's powerful stopping ability. The popularity abruptly ended once the same builders and riders realized that under the chainstay was a less than convenient location for brake maintenance and made for a tremendous mud and debris catchment area. I've owned a few such u-brake equipped bikes, and though the reason the design was quickly dropped remains potentially problematic, the brakes are dependable and powerful if properly adjusted.
I've yet to get my hands dirty with this Stumpjumper, but that I will rebuild it is not in doubt. I'm happy to have saved the bike from an ignominious end, and I know it has at least a couple more decades of service within its capacity. Whether it will be with me or with someone else is yet to be determined.
Bikes like this Stumpjumper are the antecedent to a growing renaissance of steel, multipurpose, high utility bikes, such as the Surly Long Haul Trucker and the Surly Troll, among others. While at present it seems absurd that a desirable Surly frame will ever make its way to a dumpster, 25 years ago it seemed equally improbable to one day discover a Stumpjumper in the trash. I can only hope that in another quarter century, I'll be the lucky one to find a crusty old Troll next to yesterday's coffee grounds.

|The Mountain Fair in Carbondale had lots of bikes around, and perhaps the biggest concentration of Xtracycles per capita of any place I've been.|
Mountain towns offer some great bike spotting opportunities for an aging bike nerd such as me. The bikes to be seen did not disappoint. Foremost in my notice are the many vintage mountain bikes, some of which exhibit evidence of years of heavy action, while others appear nearly unused. I saw far more neat old bikes than I had the chance to photograph, but here are a few that I captured.
|This circa early 1950s cantilever framed Schwinn has a bent seatpost and a newer saddle, but otherwise looked to be in fine riding condition with an admirable patina.|

|Lousy photo aside, this 1988 Fisher Hoo-Koo-E-Koo was mostly original, sporting a pair of Fisher Fattrax tires. Fisher Fattrax were my favorite treads from the old days, but were discontinued nearly 25 years ago.|
|Aspen's bike sharing system, known as We-Cycle, appeared to be well utilized and contributed to the town's bike-friendly vibe.|

Back at home, we've had a lot of rain since Monday. Although this is Colorado's monsoon season, it seems as though the rain has been more intense the past couple of years. I suppose that's good for keeping wildfires at bay, though I'm certainly not accustomed to overcast, wet days. I don't know how people in wet climes survive.

|Nope. No sealant. Dry as a bone.|
Off and on, I'd been wondering what was going on inside the tires during the past nine months, so when I went out to the bike barn and found the rear completely flat, it was a opportunity to take a peek.
First I tested to see if there was an obvious, egregious leak by pumping it up. The tire held air fine, though it lost much of its pressure in a few minutes. So, I popped one of the beads open and discovered that the Stan's sealant had disappeared.
In all, remarkably quick and easy, especially considering the epic struggle with the same brand of tire and rim that I experienced not long ago. In the end, it's been well worth the time investment, and gets easier each time.
Now, for no particular reason, some recent photos from my yard.
