Reliable after 3 weeks of use
After 3 weeks of moderate use, one trip to Northstar, and one redo of cable, I have to say that this cassette has been worth every penny! I converted my 2x8 to 1x11 and have had great success in doing so. Easy to install, adjust and has proven to be reliable so far!

Order the 5100 derailleur as well.
Need the matching Shimano derailleur for the larger sprocket and it works perfect. Great upgrade for an older bike that does not break the bank.

Great Range and Shifting For Little $
Got this cassette to expand the range on my old MTB that I converted to a gravel bike. I didn't have to upgrade to the newer style freehub body, so I could just swap this for the old cassette and put on a new derailleur and I was good to go. Shimano always shifts smoothly, even in their more budget-oriented products. You can easily spend 5x as much money for a 12-speed cassette with basically the same range (which also would have required me to buy a new shifter, and freehub) or you can go this route. This is cassette is definitely a great bang for your buck.

1 x 11 drive train, by shimano is truly exciting an compadent
Great item! And it looks absolutly outstanding on my bike. It makes an exciting ride, go above and beyond while grabing another gear as you are peddling wide open As you take in the changing trail ahead. And to know the gear you will need to continue shredding, and not breaking stride,the gear you will need next, will be right there when you ask for it ! Confidence Rocks

Great for a 1x gravel build
Used on a 1x bike build with a sram flat top chain and a Wheeltop shifter - works amazing. Only downside is that it's pretty heavy. But it's a big cassette!

Perfect for a 1x11 upgrade.
On the heavy side but is the best option for converting to a 1 by with a non-boost frame. My rig was 3x9 stock, I upgraded to 2x11 and when this cassette came out I got rid of the front mech altogether. Shifts great, has decent road speed and climbs like a beast with a 34T ring up front.

Great cassette for low price. As usual, make sure this actually fits with your rear derailleur, both for 11 speeds and max compatible sprocket size.
