Sprockets

[PimpS]

Hello guys!

After driving almost 1400km with my PimpSerS and after having info of my mechanic from the start that my almost 12 years old chain is good only for this season, i decided to buy a new set of sprockets and chain. I'm having a pretty good dela on chain and sprocket kit (Chain is DID x-ring).
Check the link and tell me if this kind of sprockets are good. They are metal ones and i believe the metal is the best.

May be i'm too cautious, but the slack is much beyond advisory of manual, and the chain is really bad, it moves side to side to a lot and having developed a true love to my bike and myself, i'm getting this thing done, even though the old chain and sprockets have made only 10k km. I'm thinking of making some distant trip in a month to sea side and broken chain or something like it, don't want to have these kind of problems on my road menu.
Next thing is crash bar and some minor accessories (ketten max, light visor...)

Any respond and comment of buying these sprockets are welcome, thank you!
