The M770 XT cassette is one of the best ways to lose a chunk of weight without breaking the bank. Featuring an aluminum carrier that saves weight and adds rigidity, meaning you get better shifts, more efficient power transfer, and increased happiness. The steel rings used on this cassette will give you a longer wearing piece that will provide more miles of fun. The cut way design sheds mud for when the skies open up and you get caught out on the trail.

Do you sell just the first three cogs of this cassette (the 11, 13 and 15t cogs)?

Unfortunately, both sources for Shimano have discontinued the replacement outer cogs which were available in 11 or 12t to match the cassette configuration. I don't see a part number current or discontinued for the other cogs.

I purchased this cassette to mate with my XTR derailler, shifter and chain, would have liked the XTR cassette to match but it was a lot more money. This cassette works great not to heavy and silky smoth shifts. I try to avoid shifts while climbing cause it just hard on components on never very smooth but on a couple occasion I have and this cassette hooked right up. I would definatly buy this one again.

Have used the Sram equivalent(PG990) for the last several years but heard some good things about the XT cassette and figured i'd give it a try . The XT is a couple of bucks more than the 990 but Tree fort did a sweet price match so it worked out to only ten dollars more than what i pay for the Sram . My whole drivetrain is now new so shifting is as crisp as it gets . I also replaced my XTR derailleur with an XT to save a lot of money and it shifts at least as good so im not going back to the high end stuff. So far i am very happy with this cassette .

Replaced worn Sram 9-speed cassette. Shifting is fast and quiet. Couldn't ask for anything more.

So far so good but have only ridden it twice for about 45 miles. I ride pretty hard on some rough trails. Forgot how nice it is to have unworn cogs! Go with 34 teeth on the biggest sprocket if you do hard climbs.

I bought the xt cassette as a replacement for my sram 990. This cassette is super quiet and shifts very smoothly. So far I am very happy with the performance.

what's there to say, XT cassettes are workhorses. Nicer to my aluminum freehub body than equal level SRAM cassette and since I go through at least 2 of these a year way easier on the pocket than XTR.

A worthy investment. The XT cassette allows for great shifting and power transfer. I've never used an XTR cassette, but I've used Sram 970 and I think that the XT is slightly better.

I bought this Shimano XT 9-speed cassette as a replacement for my SRAM PG-990. The rest of my drivetrain is SRAM, but I gotta say I'm sold on the Shimano cassette. It's lighter and seems to be holding up just as well as the 990 did. Definitely the best value for a 9 speed cassette out there!
