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.
Good
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
