Purchased this 11-46 cassette to upgrade from a Shimano 11-42 cassette 10 speed for my older XC bike with a 30 tooth single chain ring and 175mm cranks up front, non-boost. I've always liked the Shimano oldie but goody 10speed drivetrain over the 11 speed for some reason. The 11-46 cassette precise shifting closely feels like the modern 12 speed XT 10-51 cassette quiet up or down shifting. I'm not saying it has the same technology as the 12 speed drivetrain, but man, it's close. Highly recommend this cassette if you have and older bike that needs a freshening up, buy it.
