I'm running SRAM chains on all of my bikes.
That's what I've done for about the past thirty-five years or so. You might say it's one of my few brand loyalties (along with Mavic rims, Brooks saddles and, yes, Mercian bikes) in cycling.
In a sense, though, my use of SRAM chains isn't a brand loyalty. You see, when I first started riding with them, SRAM didn't exist. How's that, you say?
Well, back in the '70's, before Campagnolo, Shimano and SRAM became the main suppliers of quality bicycle components, there were many more independent manufacturers than there are now. Most of them were relatively small, owned by the families that founded them. Some, like Brooks and Mavic, survive today, though under the umbrella of larger companies. However, many--like SunTour and Lyotard, which I mentioned in earlier posts--folded because of mis-steps (SunTour with its indexed shifting system) or simply not updating their products (Lyotard and many other European companies). Others were bought out by larger companies and saw their venerable names relegated to the tire tracks of history.
One such component-maker was Sedis. Actually, they made one category of bike parts: chains. Nearly all French bikes came with them. They also were common on machines from England and other European countries, as well as Schwinns. Also, Sedis chains were commonly purchased as replacements, sometimes for chains that hadn't worn out. I'll explain that in a moment.
Sedis chains were popular mainly for the same reasons as SunTour drive train components and Lyotard pedals: They worked well and were well-made and reasonably-priced. Those attributes were most apparent in what might be the most iconic product Sedis ever produced: the Sedisport chain.
Until Shimano came out with the Uniglide in 1977, nearly all chains had flat side plates. Shimano designed this chain, with its bulged outer plates, to work with the twisted-tooth sprockets made for their then-new cassette freehubs. (Until 1985 or so, Shimano also offered thread-on freewheels with twisted-tooth cogs.) Around the same time, SunTour developed its "Ultra-six" freewheel, which fit six sprockets in the same amount of space as the five rear sprockets that were standard at the time. Sun Tour also marketed a chain, made for them by HKK, with narrower outer plates and pins flush with them. All bike chains up to that time, including the Uniglide, had pins that protruded slightly from the side-plates.
The Uniglide and HKK/SunTour chains shared a problem all Japanese derailleur chains had in those days: They stretched and wore very quickly. And the Uniglide was one of the noisiest chains ever made: Comparisons were made with Harleys and trucks.
In 1978, Maillard (which would later share Sedis' fate) made its own version of the Ultra-Six freewheel. The Sedisport was created to work with it. Originally, the chains were available only in a traditional black finish, but gold and silver versions would become available.
The basic black version could be had for about $5-6, the same price as just about any entry-level derailleur chain. The gold and silver versions were, naturally, a few dollars more. They were among the greatest bargains in the history of cycle componentry.
When you took a Sedisport out of its packet (for the black version) or box (gold or silver), it seemed almost floppy, especially to someone accustomed to a Regina Oro chain. That was a function, not only of its narrower side plates and flush pins, but also of its most revolutionary design features: slightly flared inner plates (as opposed to the bulged outer plates of the Uniglide) and, most important, its bushing-less pivots.
Those features made the Sedisport both stronger and lighter than any of the other chains I've mentioned. And, the fact that it had fewer moving parts meant that it didn't need to be cleaned and lubed as often, and didn't jam or develop stiff links. And, best of all, it shifted even better than any of those other chains--yes, even on SunTour's Ultra-Six or Shimano's Uniglide sprockets. And on Regina freewheels.
As a result, nearly anybody riding any derailleur-equipped bicycle of anything more than department-store quality had a Sedisport chain. It's what I rode on my Colnago; I knew other riders who installed it on bikes equipped entirely with Campagnolo Super Record equipment. Up to that time, the custom was to team up a Regina Oro freewheel and chain with a Record or Super Record gruppo, as Campagnolo did not make freewheels or chains. But Oros cost about three times as much as Sedisports and didn't last as long or shift as well. Regina developed its own Ultra Six freewheel (They had a standard six-speed, which was wider than the five-speed) but their quality was slipping. So, many racers and other performance-oriented riders switched to SunTour Winner freewheels along with Sedisport chains even as they continued to ride with Campagnolo cranks and derailleurs.
Every new model of derailleur chain made since the Sedisport--whether for seven, eight, nine, ten or eleven speeds--has been made without bushings, and with curved or flared inner plates and pins that are flush with the outer plates. Among those modern chains are today's SRAM chains.
That last fact makes perfect sense when you realize that SRAM chains are Sedis chains. In the early 1980s, Sedis's bicycle chain division, along with Maillard (which made freewheels, hubs and pedals bearing the Normandy and Atom as well as Maillard brands) and Huret were purchased by Sachs, a German maker of coaster brakes, multigear hubs and components for mopeds and motorbikes. Through most of the 1980's, the chains were sold under the Sachs/Sedis marque. Then, in 1996, Sachs became part of the SRAM group. In the beginning, SRAM components were made in the original French factories that produced Sedis, Maillard and Huret stuff. But in the early 2000s, most production shifted to Taiwan. However, SRAM chains have been made in Portugal.
Through all of these changes, SRAM chains retained the qualities that got me (and so many other people) to ride Sedis chains so many years ago. I've tried Shimano (as well as other chains) on my Shimano cassettes and Rohloff as well as Wipperman chains on Campy stuff. SRAM chains always worked better and lasted longer--and were usually less expensive to boot.
Interestingly, the Sedis name survived the buyouts. It currently manufactures chains for industrial purposes in Troyes, where Lancelot was born, if you will. They first started making chains in 1895, when they were part of Peugeot. (Most people outside the Francophone world don't realize that Peugeot is a large, 200-year-old, industrial company that makes everything from peppermills to trucks.) At that time, Peugeot manufactured in Isere. In 1946, the chain division merged with two other chain manufacturers, Societe Verjoux of the Doubs region and Societe des Chains Darbilly in the Seine region. The name SEDIS is an acronym of SEine, Doubs and ISere. They continue to use the logo familiar to so many of us.
