As described in my article on the American Bike Boom of the 70s, millions of bicycles were sold during the Boom, but just because people bought the bikes doesn't mean they actually rode them. Barns, basements, and garages all over America have been hiding innumerable examples of bikes from the Boom and the decade that followed, many of them having barely ever been ridden. Some of those 70s era machines, while dated, could still make decent riders -- city bikes, commuting workhorses, etc. -- without breaking the bank.
Mid-level bikes from the Bike Boom could be pretty nice. Look for lugged frames and frame tubing stickers that identify a better-quality tubing. Some mid-level bikes might have Reynolds tubing (either the straight-gauge version -- or perhaps the 3 main tubes only), or Vitus or something else. Japanese bikes might be labeled with Tange or Ishiwata -- maybe a manganese alloy, occasionally chrome-moly, or something like Fuji's Valite tubing. Aluminum rimmed wheels are a nice feature on some of the mid-range bikes, which means one less thing that needs to be updated, assuming they are in good shape. Though some mid-level bikes from the period still had cottered cranks, the better ones would have some kind of cotterless model. In the early 70s, even some high end bikes still came with center pull brakes, so don't let that throw you off. Schwinn's mid-level bikes, like the Sport Touring and Superior models look at first glance very similar to their low-end Varsity, but look more closely to see a sticker identifying them as having chrome-moly tubing. Those bike are lugless -- fillet-brazed -- and some of them sell for more money than one might expect (a lot of people have a soft spot for old Schwinns -- myself included). Making component upgrades/updates on these bikes is subject to less debate, but one should still consider the cost of those upgrades -- set a reasonable budget and try not to exceed it. Try to remember that bikes like these are not financial investments, but they can be very nice to ride, which is a completely different kind of value.
Higher-end bikes from the Bike Boom and the rest of the 70s can be real classics. Raleigh's Professional and International models, Peugeot's PX-10, Gitane's Tour de France, the Schwinn Paramount, and many more, were built with high-quality tubing (usually Reynolds 531, but Columbus or Super Vitus could also be found on some models) and most were equipped with good componentry throughout. Look for cotterless aluminum cranks, like Campagnolo, Stronglight, or TA. Campagnolo parts are a good sign of quality and value in general, though some good bikes from the period will have Campy Nuovo Record components all around, except for the brakes which might be center pulls. Some of the French bikes in this category might still have those awful plastic Simplex derailleurs (replace that with a vintage Simplex Super LJ, and you've really got something there). A lot of the higher-end bikes were equipped with tubular/sew-up tires.
These higher-end bikes are definitely worth keeping and riding, and very few changes would be needed for a lot of them. Because these bikes are usually worth more, and some of them might even have collector value, it might be worthwhile to keep them "period correct." If one wants to update components to make the bike more friendly to their current riding style (such as wanting clinchers instead of tubulars, or a change in gearing, for example), I might suggest keeping the original parts set aside so the bike could be returned to its original state should one decide to resell it someday. With the lower- and mid-range bikes, I wouldn't hesitate to re-paint or even powder coat a frame with battered paint -- but with these higher-end models, or any bike with some collector value, I might be reluctant to do anything that would lower the value, or which couldn't be undone later. Having said that, I should also make clear that the bikes I'm describing here were still mass-produced in huge numbers in big factories, so don't feel too paranoid about making changes to them if it makes the riding experience more enjoyable. They were meant to be ridden, after all.
If someone wants more info on some of the classic bikes and models from the 70s, I'd suggest looking into the Classic Rendezvous site. For more useful info on updating Bike Boom era bikes, the late Sheldon Brown's website has a lot of tips.
Overall, the bikes from the Bike Boom era have a lot of classic style, and it's a shame so many of them sit languishing. If someone finds one of these bikes and gets a decent deal on the price -- again, garage sales are where the bargains are -- there are some worthwhile upgrades that can make them sweet-riding bikes. Vintage bikes like these are satisfying to get back on the road, and will very likely turn heads wherever you ride.
This Fuji Special Tourer, and the orange one above were on eBay recently from the same seller -- asking $300 for the pair. Both bikes looked to be virtually new. |
