SRAM v XT Cassette

FSR_XC

Currently using an XT rear cassette.

Thinking of using an SRAM next. Either pg-970 / 980

Are there any compatability issues?
Do they fit the same?

Is there much difference in performance?

no compatibility issues.

other than lose steel cogs and alloy bodies.

The SRAM ones are slightly heavier (even the 990), aside from that, go for it

I have found that the XT cassette lasts slightly longer but there isnt much in it I would just go for the one that is cheaper

SRAM PG-970 uses a rivetted steel stack assembly so unsuitable for lighter weight hubs that use an alloy freehub body like Hope Pro II or Tune

for those types of hubs use the SRAM PG-990 which has an alloy spider assembley

the PG-990 is definitely lighter than the PG-970 and a little crisper under heavy shifting as the spider makes the cassette stiffer

the XT cassette falls between the two SRAM cassettes in price, and also has an alloy spider

you won't really go wrong with either XT or SRAM PG-990, or the Deore and PG-970 if on a budget and using hubs with steel freehub bodies

FSR_XC

The hub is XT.

Rob - you seem to now a bit about the make up of the cassettes, however you haven't mentioned the PG-980.

Where does this fit in with the Shimano stuff - LX?
