In 1979 my college graduation present to myself was a 12 speed. I still have it, and it was well-maintained until I was hit by a car fairly recently. (Okay, technically I hit the car, but the end result was the same.) Once my road-rash cleared up, I went to the local bike shop in need of new wheels, fork, brake and crankset. The proprietor no longer stocked either 27" wheels or freewheels, but he let me in on a trade secret: The best place to get those parts is the local dump or at yard sales. He told me that he himself literally threw away about fifty bikes a year. Sure enough, I started looking over the scrap metal pile at the local recycling center on trash day, and within a few weeks I’d found everything I needed. And the quality was better than that of the originals. Hmmm, I was on to something. Since then I’ve assembled several more bikes for myself, and one for my daughter to take to college this fall, and I’ve upgraded our components when opportunities presented themselves.
If you’re interested in the economic and ecologic sense of alternative transportation and don’t already own a bike, this is a chance to experiment without a large investment. If you have an old bike with sentimental value in your attic – a friend that’s carried you thousands of happy miles – maybe it’s time to put it back in service with upgraded brakes, wheels or drive-train parts. If you already have a nice bike, you might also want a "beater" to ride in the rain, or where theft is a concern. The uglier the better, but it should still be in excellent mechanical order. Get over the pride thing, if that’s an obstacle. Re-using is the ultimate form of recycling, and good for everyone concerned. Consider the energy and material resources it took just to mine the ore for a bike’s metal, let alone to manufacture, market, package and ship it. You’re doing yourself and the world a favor by rescuing and resurrecting one.
Now, back to the scrap metal pile: One might get lucky and find a complete bike in good order, but usually parts are missing or damaged - most often wheels, saddles and pedals, so grab those whenever you see any worth grabbing. Frames will occasionally be of aluminum, but usually of steel. Avoid cheap spot-welded frames with stamped components. While they can be made rideable, they will never be rewarding and aren’t worthy of your time and effort. Good steel frames will be "lugged" – made with sockets that strengthen the joints between tubes, the areas of highest stress. Another quick way to recognize quality is to look at the right crank and "spider" – the starfish-shaped piece that the front chainwheels are bolted to. If they’re cast as one piece, it’s a decent bike. Look, too, for wheels with alloy rims and stainless spokes. Steel wheels are heavy and unresponsive. (Hey, I think I was married to one of those once ….) If a bike’s frame is the wrong size for you, maybe it’s the right size for someone you know. Or maybe the components are worth salvaging.
Give any older bike a thorough going-over. The bearings should be cleaned and repacked with grease. New brake pads are always a good idea. Even if they aren’t worn, they harden with age. Modern cables have stainless steel wires surrounded by a low-friction liner, conducive to clean, quick shifting and braking. Older unlined cables should be replaced. The handlebars will likely need re-wrapping. Look in used book stores for a repair and maintenance manual with a copyright date in the appropriate date range. While you’re at it, get a book or two about how to ride – there’s more to it than you might think. The mysteries of adjusting derailers and servicing headsets will be solved once you sit down with a book and your bike and follow the procedures step by step. You may feel more comfortable if you dissect a junk bike first, just to see how things work, before you begin on your legitimate restoration project.
Once you have what you’re looking for, throw away anything on it that adds useless weight. Those brake extension levers on some bikes, for example. At best, using them will teach you poor riding habits. At their worst, they can be dangerously inefficient. If you prefer straight handlebars and upright brake levers, you can create a hybrid. If the front derailer is damaged, save yourself some weight and complexity and do without it. Remove it and one of the front chain rings, and you own a five-speed. Do you really need any more? If you don’t have many hills to contend with, consider going all the way to a single speed. This will relieve you of the need for the rear derailer, all the rear sprockets but one, and the shift levers and cables. It will save a few additional ounces with a shorter chain, too. A singlespeed is noticeably more efficient than a multispeed in the same gain ratio because of it’s lighter weight and the lack of drag from derailer pulleys. There are several websites that will guide you through the process so that you’ll end up with the requisite straight chainline. Maybe you’ll recapture some of the simple fun you experienced with your singlespeed childhood bicycles. If not, all that’s lost is some time spent in enjoyable, stress-relieving tinkering. Another option for a missing or damaged rear wheel is to replace it with one that has a more modern cassette-style freehub. This may involve spreading the stays of the frame to accommodate a wider axle, but it’s not rocket science and again there’s plenty of information on the web.
While I have a generally minimalist philosophy, there are some things that are worth adding to a bike. Flat tires are by far the most common mechanical malfunction, so a patch kit and tire levers should be in a small bag under your saddle, and a frame-fitting pump on the seat tube. On a long ride, your hands will appreciate rubber brake hoods. Toe clips are considered obsolete by some, and take some getting used to, but they’ll convert the energy you use just to keep your feet on the pedals into forward motion. (Clipless pedals are even better, but require special shoes that you won’t want to walk around in at your destination.) A water bottle will fuel you so you can fuel your bike. Lights are necessary at night. Those with LED’s are remarkably efficient and long-lasting. I’m ambivalent about fenders and racks – if they make sense for you, put them on. Small fenders are useless, but full ones will keep you drier and your bike cleaner if you’re not just a fair-weather cyclist. If you carry paperwork or lunch or clothes, a rack will keep your center of gravity lower than a backpack will. Locks are an unfortunate necessity.
Cyclists tend to be friendly folks who will cheerfully help you. Chances are you already know someone who would be glad to advise you about refurbishing a bike and fitting it to you.
Happy riding-
