So I have a fit prospect that I got 3 months ago and my chain is always loose even tho I tighten it. I got a new kmc chain about 2 days ago and tightened it but it is still loose and it is hitting the cs. I can't shorten the chain because it will be too short and won't fit , so what should I do? Please help.

Stick something in between the frame and tire that will keep the chain loose and then tighten the shit out of the rear wheel bolts

Pull your wheel back! Are you sure you're tensioning the chain and properly tightening your nuts/bolts?

Tighten them bolts up! Your chain naturally pulls the wheel forwards to become looser as you pedal, and pressure is applied on the driver, so you gotta tighten those things real good, especially if you're a peg rider.

Looks like you'll have to buy a new frame to fit your new chain

No, that doesn't have anything to do with this.

Something obviously isn't being done properly. List out your steps here.

A half link MIGHT aid in the issue, but there is not really a reason you shouldn't be able to run what you have.

Post up some photos of the bike as is, and when you have it CRANKED as tight as you can.

Descriptions only go so far.

ok , so both of my bolts are loose so I can pull back the wheel, then I have someone else take a thick ended metal wrench and use the butt end and put it between the wheel and the frame . Then they pull on the wrench to create leverage and push back the wheel , but the bolts almost come of the frame at the dropout because how pushed back it is , but the chain is somehow still very loose and drooping , do u think it could be an extra link that I have to take out ?

If your chain is on the sprocket and driver and you can pull your wheel out of the dropouts, you need to remove a link or 2.

Also, I'd avoid using that method. You're far more likely to snap a chain or blow up driver bearings doing that. Just tip the bike up so it's resting on the bars and front wheel, then put the wrench on the drive-side and pull back until the chain is tight and just tighten it up. Then you can do the non-drive side, get the wheel centered and tighten that side down as well.

Yeah, exactly this.

Mind posting up a photo of your wheel when it's all the way back? This way we'll know for sure, words can only go so far.

Could the dropout be bent or are the cranks loose and shifting left to right?
