    A new, different chain situation

    Maybe you guys can figure this out, I can't. Here's the deal:

    Bought a new chain, 3/32 Taya Pro Releif
    Attempted install on newish 3/32chain ring and cog - I try to keep the chain pretty fresh to slow the wear on the drive train. Here's what happened:




    So, I buy another 3/32 chain in the same brand as the original and it fits like a glove.

    But wait, curiosity and confusion results in checking the chain above on another bike. Here's what happened:




    Fits like a glove.

    So in summary:
    NIB 3/32 chain does not fit on a new 3/32 drive train.
    Does fit on another 3/32 drivetrain.

    Different NIB 3/32 chain does fit on a new 3/32 drive train.

    currently my 2 piece cogs are only to be run with a true 3/32" chain.... i can see by the pics that it can't be 3/32", but likely a 9 or 10 speed version, or just a really out of spec chain. I believe WI is the same way, hence why it doesn't fit that either. I could be wrong with WI, but it is clearly too narrow to fit regardless, so that chain is likely WAY undersize. The chain is too narrow to fit on the teeth completely.
    Surly makes their stuff way undersize so it'll fit anything. The downside to that is less surface area, faster wear and more noise.

    I bet you put it on backward. Turn it around and try again.

    Is it backwards? Or just upside down?

    Ok, thanks ISAR.

    I'm glad to know what it was but embarrassed I didn't know that 3/32 chains are not all the same in terms of fitting on 3/32 rings/cogs. Excuse me while I go Sheldon Brown it...

    I had that happen on a brand new Wipperman 1/8" chain and brand new Endless Kickass 1/8" cog. Go figure.
    I see hills.

    I want to climb them.

    I haven't seen a 3/32" chain that wasn't fitting yet, it's only been 9 or 10 speed chains. My guess is somehow a 9 speed chain ended up in the wrong box, or the company who makes them figured it didn't matter, and just labeled them 3/32". I find a lot of the chains not make by the big 3 (KMC, Shimano, and Sram) are kind of funky and don't mesh well with some gears, as mentioned above with the Wipperman. Their 10 speed chains have been an issue for me, way more narrow than others. It sucks when you have to modify your products in a negative way to compensate for unstandard products. I have the same issue with the 34564576585664423534654 different sizes of freehub bodies on the market. Cogs fit tight on some, but loose on others.
