Not only do some of your replies terrify me but they also give me hope…great tension there, friends. :) I’m rooting for hope…hope that all these insights eventually solve this problem so I can go about my usual way of NOT thinking about my bicycle as I ride it.
Ryan: yeah, it’s counterintuitive to replace a brand new cassette which shouldn’t be in bad shape, but we did it anyway…just covering all the bases. Eric Marth: your derailleur pictures look horrifying to me! But it gives me hope that you, too, experienced this same issue, and now you don’t. Hopefully, the cassette replacement on my Platy would have turned up a loose lock ring…if it did, I’m almost sure my bike-mechanic guys would have told me. IDK.. And it’s super helpful to see the image you sent in conjunction with your explanation. I never set out to learn this stuff, but I’m taking it all in. And I’m really glad you’re okay after your mishap. Eric Daume: I can’t quite understand if you’re referring to my cassette (which is 9 gears) or Eric Marth’s cassette. Either way, I’ll somehow tactfully question my bike guys if my cassette/hub arrangement might need a spacer.
