    I bought this to replace a deore cassette to run with a Oneup Components 42t and 16t expander. It worked perfectly. The shifting even with the different cogs swapped in was strong and positive. The chain drops onto the next gear with a audible clunk, which I don't mind. There was a small weight savings in the swap as well. Every little bit counts.

    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.

            Crisp shifts happen every time. Pretty light and seems durable so far (9 months' use). 5 minutes to install and done.

                      I've had three of these cassettes fail in the last year. Every single one of them broke where the 4-5-6 cogs rivet to the spider. I rider a 29er, so maybe it's an issue with wheel size and having too much torque with the bigger wheel, but no matter what it is…it shouldn't fail like this.
