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.

Bought to replace the original cassette on my enduro bike, I’ve been running the Shimano M8100 drivetrain on my bikes for about 5 or 6 years, due to the reliability, durability, performance and value for money.
Can’t fault it.
