SRAM XG-1299 Eagle 12 Speed Cassette
Freedom
Free at last. You are all now welcome to toss all front derailleurs right out the window. The SRAM XG-1299 Eagle cassette, with its whopping 10 to 50 tooth 12 speed range, has taken all reasons to continue fussing about with a 2x drivetrain and pushed them out of the nest. This cassette now offers riders a 500% gear range which is 20% more than any other current system out there. It carries with it X-Dome technologies which have, for quite some time now been touted as providing the strongest cassettes on the market. Compatible with XD Driver bodies, sports new shifting characteristics, better chain retention, and a durable titanium nitride finish.

Worth it
The mud-shedding capability of this piece of hardware is impeccable. Also it looks real good. Absolutely worth the upgrade if you can afford it.

Perfection
I think SRAM's Eagle 1X12 finally makes the 1X drivetrain a viable alternative to 2X and 3X drivetrains. I bought a bike with a 1X11, with a 32:42 low gear, and it made my ankles hurt after only a few rides at my local playground. I was used to my old bike's 3X9 drivetrain with a much lower 22:34 low gear. I switched to SRAM's Eagle 1X12 with a 32:50 low gear, and it has made all the difference in the world.

Will the 12 speed Eagle cassette work on a non-boost bike? Want to upgrade from the 11 speed XX1.
BEST ANSWER: It will work on a non boost spacing. But you definitely need an XD drive hub to fit the 10-50 12 speed cassette. And also make sure the crank offset is the non boost version for the correct chainline.

the new eagle drivetrain 12 speed. How is the durability of the cassette? What is the life span of the the cassette and chain?
BEST ANSWER: The durability of the cassettes and chains on the new Eagle 12 speed is vastly improved over the previous 11 speed generation due to new profiling and machining, primarily on the 12-speed chain. SRAM has reported chain, chainring and cassette life to be up to 4x the previous 11 speed lifespan. Since the cassette is machined from hard tool steel, longevity should be very good, however riding style, trail conditions and maintenance of components will inevitably cause the reported mileage to vary widely, so there is no good answer. Anecdotally I have seen XX1 cassettes last many years with proper care, but it really depends on how and where you ride, so it's impossible to tell. Your mileage may vary.
