    Lighter than I imagined

    My bike isn’t the lightest, so I was worried upgrading to 12sp from 11sp would be noticeable but pleasantly suprised and the switch to 12sp with the new lower and higher gears really has been a game changer on the trails

    Great upgrade

    Used the XT to upgrade from the basic Deor Cassette.

    seems to ride a lot smoother, but that could be down to not being worn as the deor was.

    Surprisingly light

    Much better than the 11 speed version, most of the cassette is one piece. Supplied with the lock ring.

    Probably best Shimano 12 Speed Cassette

    Don’t waste your money on XTR, save money and buy the XT one instead, it’s every bit as good (over £150 cheaper) and only a small handful of grams lighter.
