Yes, it's true the other way around. The chain wears on the sprockets just as much as the sprockets wear on the chain. If you're going to change either the chain or sprockets, then it's suggested that you change the other as well.
New Chain?
I have an 07 that is about 1 year old. It has about 6.5k and the rear sprocket is out of round. I'm going to gear the bike down one tooth in the front and up one tooth in the rear. My question is do I need to change my chain? I've heard that if you change the chain you should change the sprockets. Is this true the other way around?
Also, it appears that the nuts holding the rear sprocket on appear to be locked into place via a metalic dot (solder?). Will I be able to just torque them off?

Understood, but even with only 6500 miles? Thats only like 1/3 the life of the chain.Yes, it's true the other way around. The chain wears on the sprockets just as much as the sprockets wear on the chain. If you're going to change either the chain or sprockets, then it's suggested that you change the other as well.
Also, You live very close to me. I live in Providence Village and work in Denton.
I think you'd be fine without changing the chain, it's just suggested. You'd might as well knock out a 520 conversion while you're at it. In addition, I'd recommend going +2 in the back with your -1 in the front. I recently made this change and it's like a new bike. Read some other posts on this change.
Yeah, I live and work in Denton, while working through school.

I put a new front sprocket on my last two bikes and it didn't seem to hurt anything. It may wear the new sprockets faster than having a new chain put on with them...but I didn't notice anything like that and being a poor college student at the time, I couldn't justify replacing a perfectly good chain. I vote keep the chain.
how the hell did you get your sprocket out of round?
+1 good question...how the hell did you get your sprocket out of round?
opcorn2:Not sure. I first noticed a surging in first gear just cruising around my neighborhood and thought little of it. Put it on my stands and was lubing the chain when I noticed a tight and loose spot when I was spinning the rear tire. Power wheelies maybe? I really don't know.how the hell did you get your sprocket out of round?
About the 520 conversion, I'm not totally sold yet. Yes, I understand about rotating mass, but if I'm not keeping a steel 530 sprocket round the 520 will be even worse as it is thinner. I'm still considering because this would not be that much more $$ than new sprockets if buying together as a package deal.
