  1. How did you not notice the noise?

    If my derailleur isn’t running smooth and is extra noisy… I try to fix it.

    The point of this is to keep the chain in the jockey wheels as things bounce around. If it’s grooved it’s fine since it’s more just a guard. But you really should fix it.

    You are not the first – only I noticed before the ride. I have even seen this done by “professional” big box bike assemblers.

    You can probably fix this without opening the chain by loosening the screws in the jockey wheels and rotating the inner half of the cage until you can move the chain over the tab.

  3. We’ve all done it, but I can’t say we’ve all then ridden 100s of km like this…

  4. Don’t know who put that chain there it’s just totally wrong. Chain is going over the guard.

    Wasn’t noisy? To figure it out quickly

    My friend did that yesterday. He broke his chain at the quick link then got another quick link and put it on wrong again I’m about to head to his house to give him the tool to take the chain apart. So no definitely not the only one.

    Have done it. Did it after a fresh wax, and when I put it back on I went for a ride with a friend. The whole day leading up to the ride I was telling him how quiet waxed chains run, and that he should consider it. Then I did this and we went for a ride. He was too nice to say anything until I brought it up a few days later, but it was loud AF.

  7. i have heard a reason is to have another point of support for the derailleur cage.

    i seem to do this every time i wax my chain and put it back on. learned how to remove the chain (w/ quick link) on the road just so i dont have to turn around and go home.

    on the other hand, once you fix it, you’ll feel like flying

    did it once, wasn’t my first chain replacement. I noticed the notice in a few pedal strokes, I didn’t have a bike stand at that time so it took me a couple minutes to discover my error. I laughed at myself.
