CYSKY 9/10 / 11 speed cassette Wide Ratio Bicycle Cassette Sprocket Freewheel for MTB Mountain Bike (10 Speed)

Expectations were low, but this cassette is pretty awesome! I’ve put over 1000 miles on this thing and it’s still going strong. It’s a little heavy but for the price it is great.

I put this on my second bike to cheaply give it more range than the 11-36 cassette I was running. I am running this on a hard tail bike with a short cage derailure, a medium cage would be better if you have the option, though mandatory for a full suspension due to chain growth. All of this would apply to a similar product from suntour as well. This installed easily as any other cassette. It is Abit heavier than what it replaced which is to be expected but doing some reading it seems to be on par with what else is out there in this size and price point. Shift preformance was good, would be better with a derailure designed for wider ranges and or a wolftooth goat link. Durability wise this has surprised me. I expected to see obvious wear and degradation by the end of the season but it looks good, used but nothing out of the ordinary.I would definitely buy this again as a replacement or for someone looking for more range on the cheap.

For the price this is an excellent product installed easy and it works for the first 20 miles long-term don't know yet.

It worked great for 5 months of hard riding up and down hill. The Teeth are stripping on the smaller rings, so when trying to pedal hard while in the fastest gear the chain skips once in a while. My B-screw on my derailer was set far away from the cassette, so the damage may have partially been caused by that. Overall for the price it's not bad, it gets the job done, but it ain't perfect. If you ride lift access and want something cheap, this is a decent option. if you're a big climber, then maybe go for a more quality option.

Bent a gear with less than 50 miles on the cassette

It is a very good cassette, excellent performance and sensations. It is a bit heavy. Excellent component with a very good price.

Cog spacing or shift ramps inferior. Never could get proper shifting between 3-4 and 8-9 cogs. Adjusting to upshift prevented downshift and vice versa. Only wanted this for a better climbing gear, from 38 to 42 tooth low 1st gear. Nothing out of the ordinary. 1st thing I noticed out of the box is Stamped steel cogs appear much lower quality compared side by side to the OE Shimano cassette, that shifted perfectly. Even after a new 10 speed Shimano brand chain, Goat Link derailleur extender, shift cable inspection and lube, and fine tuning for a couple days, never could dial those 2 shifts in. I roughly measured cog spacing, seemed fine and looked fine, so I suspect shift ramps are the issue. Returning cassette, with the satisfaction knowing I tried everything to make this cassette work. Replacing with Shimano if I can find one.

Fantastic and easy to install
