    And yes, the wheel would have been off.

    To re-assemble for the sprocket, those two parts HAVE TO COME TOGETHER AS SUCH.

    If it's not, that bracket is VERY LIKELY BENT.

    I'd have that shop purchase you a new bracket and install it correctly or have another qualified shop do so...

    I guess I am not entirely sure even looking underneath the bike if it is in place. I'll try taking a look again in the morning when it is bright outside.

    Tried to get a hold of the shop but the guy/owner of shop is on vacation and I am not sure if anyone else would know or take my word that they were the ones that did this.

    Again, really appreciate the effort you all have placed in looking into this.

    So I know what I am looking for based on your diagrams, I just cant't tell even if I am looking underneath the bike and behind it. Took a few pics but don't think they show very well.

    I think I am able to slip my finger in the "2" spot which means it's not flush right?

    Perhaps I should just take your diagram to the shop and explain to them that's what I think is causing the noise?

    Re: Weird siren/whining like noise after chain/sprocket replacement

    That SECOND picture shows the tab NOT IN the slot.

    That bracket is very likely bent now and the tolerances don't allow for that much distortion, especially when the axle its torqued down to almost 80 lbs / foot...

    That axle has to come out, try re-assembling, this time CORRECTLY... Print out those pictures (that I circled) BIG. If it was a shop that did this, shame on them. A very rookie mistake, NOT acceptable by a shop IMO...

    Print out pictures of the brake pad shims as well. That other picture (earlier) appeared they were just jambed in there...

    Lastly, check your owners manual on how to set the chain slack. I suspect they over tightened that as well. Should be 2" TOTAL UP AND DOWN PLAY on a clean, lubed chain. Very likely, it's MUCH tighter than that...

    If you don't have the manual, PM me, I have them as a PDF..


    Where I circled is the slot in the main brake bracket. It's not slid into the tab (from what I can see-dirty and dark):

    Still haven't taken to shop due to conflicts and although I shouldn't be ridding it, I've noticed two other things:

    The whirling/siren sound only happens decelerating in first gear and not in second.

    I feel the fuel efficiency has gone south recently

    Try stopping WITHOUT the REAR brake. It should be cool to the touch.

    If the rear is binding, it's probably binding / heating up / HOT from being crooked.

    Ugh. Took it and the guy took apart everything and couldn't find anything. Said not to worry about it. Haven't ridden it to see if its worse or better but a bit disconcerning that pre new chain and sprocket no sound and now I hear things. He said chain and sprocket looks good....so again not sure. Its a good chain and sprocket so I don't believe thats the issue. Again, I'll lube and check slack this weekend but curious how castastrophic can it be?
