    I love XT components

    I am a fan of XT components. This is my first ten speed cassette and the shifting is crisp and precise. It's lightweight as well.

    Bent a cog on my SRAM PG1070 and saw that the Shimano XT was about the same weight but quite a bit less expensive on sale. Went ahead and purchased one to try out. Impression on my first ride was that I couldn't wait to get home and tear this cassette off my bike. Back to back comparison between cassettes, there is none! SRAM wins hands down. It is quieter, smoother and shifts faster. That said, after a few rides with this cassette I have gotten used to the noise and shifting and it does not bother me any more. Not enough to buy the SRAM and toss this thing. However, I will only buy SRAM cassettes going forward. For the price difference between this and the SRAM, the cassette does a descent job. If you are moving from one to the other, just give it some time to get used to it. I only run KMC X10SL chains on all of my bikes. So neither cassette was using a "factory" chain.

      This installed easily and allowed me to modify to a 42t cog. The switch was easy and shaved some weight compared to the SLX I had been running.

        Bought this XT cassette to replace the SLX cassette on my Giant Trance 27.5 1 so that I can possibly add a Wolftooth 42T ring to the cassette.

        Work great

            I picked this up in upgrading my Trek Marlin from an 8x3 drivetrain to a 10x2. I found it to be much lighter than my previous cassette and it was easy to install. So far everything is working great, shifts are smooth, low noise, easy to clean. I wouldn't pay the MSRP, but not bad with the Jenson discounted price. Only complaint is how super shiny it was out of the box, almost blinding. :)

                Comments about Shimano M771 XT 10 Speed Cassette:

                This cassette works great. Shifting is smooth in clean or dirty conditions. My only problems is that over the past year I have broken 3 of these. The rivets that hold cogs 4,5, and 6 seem to fail prematurely. In previous years I have not had such problems. Sure I'm 205 pounds and I race so I'm laying down as much power as I can but XT has always been the amateur racers best friend. Half the price of XTR and all the performance with a little more weight and, generally, more durability.
                Perhaps changing the rivets to screws would be better. At least then I could replace a failed screw and better yet, take them all apart for easier cleaning like the SRAM cassettes.
                I hope the failure problem is just a production line issue that will be resolved soon. The comparable SRAM option is a lot more moolah and the XTR is way out of reach.
