XC 9 Speeders - What chain and cassette?

so i broke my chain at my last race. luckily i had a chain tool so i could finish the race.
i tried to shift into the granny (under load ). the chain didn't drop, so i hammered up the hill instead. the torque or the cross-shifting must have done it.

anyways, i check my chain with one of those tools, and it turns out my chain is really stretched. so i figure its a good time for some new drivetrain parts.

so my questions is, what chain and cassette should i pick up. i don't mind spending for something reasonably fancy. i was thinking SRAM PC99 (maybe even hollowpin). and an XT cassette.

what are you guys running? any durability or shifting issues?

any thoughts/opinions are appreciated.

I run PC-950's on both bikes and a XT cassette on the trail bike.
More than likely I'll replace it with a SRAM PG990 when it wears out. I'm not racing and I can just about get two PG990's for the price of one XT cassette
Like I said that's me.
I've never had an issue with a PC-59 (950) or higher SRAM chain or cassette. In fact I run a SRAM R-9 road cassette on my commuter and it's quite frankly the nicest cassette I've run on that bike at any price

If you ask me, the best value in chains is the PC69. I think the 99 and 69 has a 20 gram difference of weight.
As for cassettes im running a PG970, I am pleased with this cassette

I've been running the Wippermann Connex 908 chain for the past two chain changes and have been very happy with it. Previously, I ran the SRAM PC-99s and felt that was a good chain too. I'm using the XTR cassette.

I would also suggest carrying an extra set of removable links (PowerLink Gold or ConneXlink-9) in case you snap a sideplate or something. It'll be much quicker to deal with than having to break out the chaintool. Just replace the broken link with the removable link and off you go.

I always ran the SRAM PC69 and never had any problems. I believe they have quit making it though, it's no longer in our catalog. Right now I am actually running an LX chain, no problems with it either. I will be changing my chain in the next few days though, going with SRAM 970 this time. It is a nice chain at a reasonable price. I change my chains every couple of months so durability is not a huge concern for me. It is much cheaper to replace a chain than a cassette. As far as cassettes go I always run an XT cassette. I used to run XTR but once it wore out I wasn't willing to spend the money for another one.

As far as the hollow pin chains go I don't trust them. I have seen too many of them break. I'm not willing to lose the time it takes to fix a chain to save a few grams.

Oh, and as khuon stated, I always carry an extra power link in my camel bak.

i know the XT has the one piece cog carrier (the spider?). does the SRAM have that? does it make a difference?
