    Sachs Sedis Chain experts needed

    I purchased a number of Sachs 3/32" chains assuming (and told) they were "single speed" or NON-derailleur chains. Well, I'm not so sure now. According to Bikepro, the only completely nickel plated chain is the Sedis PRO SL / SC-R80. So any accurate assessment on what model chains I have? And did they even make a single cog, completely nickel plated chain in 3/32"?

    Those are 3/32" chains designed for derailleur bikes. The dead giveaway are the contoured outer plates which enhance shifting

    Sedis did make a nickel plated 1/8" chain back in day for BMX bikes.

    I run 3/32" derailer chains on my SS, fixed and hub gear bikes with no problems.

    That is what one would normally want to do. The only exception would be a very thick cog or chainring.

    i actually did have a 4-speed derailleur/3-speed hub hybrid transmission which took a 1/8" chain, but that's the exception.

    Not really. Single speed 1/8" chains are often used on SS, fixed and internal gear bikes. Many believe that a less flexible chain is less likely to get dropped.

    I've thought that if you have, say, a Sturmey-Archer cog (made by S-A) on the rear, then you need a 1/8" chain. Is that incorrect? Can a 3/32" chain be used with them? The Harris/Brown info suggests that only the Shimano cogs (apparently thinner) can be used with a 3/32" chain.

    I had a nickel-plated sedis in my inventory years back. I bought it a novelty - but it was 3/32" and made for derailleurs. I finally gave it to a person in desperate need of a new chain to mesh the new freewheel and cranks I'd installed on his bicycle. I'd forgotten to mention he'd need a new chain and it slipped my mind. When he was giving his "new" bike a test run - I remembered. He came back to complain about......I had the sedis waiting for him - last new chain I had.
    How do you keep an idiot in suspense?

    It's definitely a derailleur chain but it's also one of my favorite chains to use on SS and fixed gears.

    I believe that's true. My Sturmey Archer 3 speed hub has a Shimano cog.

    Some of the confusion comes about due to the new fixie/SS movement.

    Back in the day fixed gear, SS, BMX and 3-speed bikes all required 1/8" chains.

    Many of the newer fixxie/SS bikes are designed around the use of converted roadbike cranks and evidently, there's a plethora of 3/32" cogs available which in turns allows the use of more narrow 3/32" derailleur chains.

    OP: any plans for those chains?

    SRAM IGH cogs are also 3/32" width. I am running with a Wippermann 1/8" chain though as the chainring on my old Sugino FG crank is 1/8". All of the SA IGH sprockets I have are 1/8" width. BTW the Wippermann 108 chain is a fully nickeled 1/8" chain.

    I bought these for an SA 8spd IGH project some months back (and yes, Sturmey offers 3/32 cogs, which I have). I realize derailleur chains are frequently used for SS and fixies, and have few qualms using them. However, being the picky fart that I am, I was hoping to use non-derailleur chains instead. Dunno now.

    I just discovered another oddity; Although NOS, the chains are only 92 links. I have 4 chains and all have the factory, unused connecting pins (as shown), so there's enough for assembling 3 complete chains. But why the 92 links?
