lighter chain and Cassette worth the upgrade ?

I'm thinking of doing a Drive Train upgrade and I'm happy with my Sram stuff

I currently have a PC-970 for the cassette and a lower end Sram 9 speed chain

is it worth upgrading this stuff to the next level of component like a PC-980 cassette and a 991 chain

I ride trails and the occasional race for ****s and giggles

imo no, these are the last pieces on my bike to get an upgrade, as long as you are using decent quality stuff for good shifting you are set, but you don't need higher end stuff to save weight, which is basically what you pay for there, the 990 cassette has a big cog holder that holds like the biggest 7 gears or somthin, so they don't bite into and alloy cassette body, but i don't think most peopel have that issue on a mtn bike, and if you do your bike is prolly so expensive that you will want to run a 990 for weight savings, but you just wear out chains and to a lesser extent cassettes. Think about how much each chain costs extra and how many chains you use in the lifetime of a bike, the diff in price between 970 and 980 is prolly enough for somthin really nice

If you do upgrade don't go 980 go all out and get a 990 (but don't)

the 970 is heavy as each cog goes all the way to the freewheel.
the 980 has half an alloy carrier for the cogs.
the 990 is a whole alloy carrier.
this will make the 980 lighter and the 990 still.

The chain is fine but upgrade the cassette for weight savings. and buy another cheap SRAM chain like the 971. The 991 chain is more expensive but wears the same as the 971 in my experience.
