I ended having to upgrade to this cassette in 2020-21 when I couldn't find anything else in stock. It was the only one left so I coughed up the $$$ and mounted it up with a full XTR groupset (figure I'd go all in the get the full XTR 12 experience) We'll I have to say it is undoubtedly the best I've ever ridden. I shift whenever I want, under any level of power, and never have to stop pedaling! Unbelievably smooth, quick, and immediate shifts. I have been upgrading all my drivetrain to XTR since.

Thanks to Thunder mountain bikes too for getting them in stock and not jacking the price up!

Great Shimano Reliability

Thunder Mountain Bikes actually had an XTR cassette in stock!
Fast shipping and great service. Not much to say about the cassette, as it is a light weight Shimano XTR 12s Cassette.
