The uninterrupted shifting experience of the Ultegra R8100 12-speed cassette range lets you climb, sprint, or cruise without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed freehub bodies.
Hyperglide+ cassettes already revolutionized off-road engagement with seamless shifts up and down the gear range, now that technology has come to road cycling. Even during maximal climbing or sprinting efforts, riders no longer need to let up for precise shifting. In any gear, Shimano Ultegra R8150 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing Hyperglide freehub bodies. All this while increasing to 12-gears.
Experience the new paradigm in road shifting with Ultegra R8100.

I don't know what Shimano does to make their cassettes and rings shift so well, but they do it the best. Under load they shift perfectly, it's amazing.
No issues, find the combo you need, wait for a sale, and off you go. No noticeable difference in longevity or anything else over an expensive model or a cheaper model, they just sorta run. 3 chains per cassette rule seems to work.
