Rated 5 out of 5 Great cassette, bulletproof Great cassette, strong efficient light enough what more could you want 20 July 2014
Rated 5 out of 5 by Fit and go Great with alloy free hub bodies like HOPE! quality great weight ok. value spot on! 18 July 2014
Rated 5 out of 5 by Excellent cassette for the older 9 speed standard This cassette has proven to have a very good durability (5k km+) and weight (<300g). It has been ridden in wet, sand, light mud and on low maintenance conditions in my commuter, without signs of rust, and just normal wear signs. Works great with a Shimano HG or a KMC 9 speed chain. As the cassette and chain wore out, I was considering upgrading to 10sp, but as I am more than satisfied with this, I will stay with my current transmission groupset. 14 July 2014

Rated 5 out of 5 by Best one I've found yet. A lot better than SRAM's My last one lasted 6 years of hard riding in all conditions. Snow / ice, mud and water. Make sure your chain isn't stretched and the cassette will last a long time. 02 July 2014

Yes, M770 is just the next year's model. All components within the same family are compatible. Eg Mega 9. I upgraded all of my components to SLX and XT. In fact, i gradually upgraded one component at a time from 8 speed to 9 speed! Hope this helps!

Answer: 
il pacco pignoni da 9v ha la stessa lunghezza di quello da 10v (che ha i pignoni meno spessi)e quindi vanno bene ambedue sulla stessa ruota libera. Per quest'ultimo però dovrai cambiare la catena che è più sottile di quella per 9v e questo ti darà problemi sulla garnitura se ha le corone per 9v.
Spero di essermi spiegato bene (disse il paracadute)

The CSM969 uses the same spine system as SRAM/ Shimano cassettes, so this XT cassette should fit fine as a replacement.

Answer: 
Hi,
That will depend on wich Ultegra rear derailleurs you have, and on the rings/teeth of your crankset.
Ultegra RDs are offered with two cage sizes. The SS (short cage) usually handles a maximum sprocket of 12-28T, and the GS (medium cage), 12T-32T.
You will also need to determine the RD capacity you need (based on rings and cassette), and compare it with the RD model you have. SS has 33T max total capacity, and GS, 41T.

In terms of compatibility with your shifter, it will work, as the cable pull for both systems is the same. Probably a new chain will be needed to accomodate the larger cogs.
