Everything else is out of stock everywhere. And besides, it will last longer than SLX or XT. Shifts/feels just as good.

Great all steel 10-51 cassette, if you don't mind the weight.
I had this cassette on my new Vitus Sommet 297 CR. This cassette along with the Deore M6100 rear derailleur shifted buttery smooth! The only thing you lose over the more expensive cassettes in the lineup is weight savings. As far as performance however, its great! This is an excellent choice for a more budget friendly 12 speed setup that performs just as good as anything out there, with Shimano reliability. Even though this is a bit heavier than the SLX, XT, or XTR, it will most likely last longer on the larger cogs due to them being steel instead of aluminum. I only swapped this out on my bike because I came across a deal on a brand new XT cassette to save a bit of weight, otherwise I'd still be using it. Amazing shifting at a fraction of the cost of the higher ... MoreI had this cassette on my new Vitus Sommet 297 CR. This cassette along with the Deore M6100 rear derailleur shifted buttery smooth!

Same great performance as XT but for less. Using this on an ebike so weight is less of a concern. Want durability and less expense and this is the best option.
works just like its lighter siblings.
Good price and excellent quality
best 12 speed cassette ever
