Need help Asap

[Shocky]

I need a 20" LSD double wall rim, i have one but im not exactly sure how much it would be to get it trued, and somethign seems wrong with the sprocket. Would it be worth buying a whole new rim or getting this one fixed?

[clokstar]

Well, if there's nothing wrong with you're current rim then I don't think it would be neccessary to actually buy another and then haev to pay to get it re-spoked and a hun put on. Getting it trued would cost wayy less. You haven't really specified what the sprocket problem is so I can't really help you there.

Is it so bent it hits the frame? If not it can probably be trued.. Probbly will cost you $15-20 dollars.

the rim is bent, and you can see when you spin it, but it doesnt hit the frame or brake pads.

The sprocket, about every half turn it gets harder to push and has a grinding feel to it.

that and when i pedal it backwards it slows down the bike and some times even acts as a reverse gear every now and then

sounds like the wheel can be trued...

as for the sprocket, how tight is the chain? that almost sounds like its a problem with your chain being too tight, and if your front chainring isn't round (most arent perfectly round) then it will cause tight spots in your chain, which will make it feel harder to push..

Just buy a new freewheel (back sprocket) they are ~ $15 and do just wear out eventually. But try loosening you chain a little first like Dirty said.
