On a deeper look and after reading some reviews here and there, I noticed that there were many people who seem to have the same problem with this cassette - The cogs on the cassette become loose after a few rides.
I started to worry a bit while waiting for the cassette to arrive (even considering canceling the order), but I said - Hey, that couldn't happen to me - Boy, was I wrong!
After mounting it, I took it to a trail in the forest, and after 20-30km, something on my rear wheel started rattling like crazy.
After inspecting the cassette, the verdict was clear: I had the same problem other people had. I thought I didn't put enough force on the cassette lockring and tighten it even more than it already was. That seems to have solved the problem, but after another ride - the sound was there again!
I removed the lockring, took the cassette cogs off, and inspect them. Nothing seemed out of place, so the only thing that could be problematic in my opinion was the cassette lockring. And, I was right.
It seems that the lockring it's shorter (it should be a little longer - see first attached image), and no matter how much force you put on it, it still won't secure the cogs, and after some miles, the cassette will start to rattle, and the cogs will move independently.
Luckily for me, I did not throw the old lockrings from my previous cassettes that I had( One SRAM, and some Chinese cassette - that lasted about 2 months - but that is another story.
)I added the lockring from my SRAM cassette( see image 4 ), and after riding the bike for 3 weeks, I can confirm that the problem it's solved, and the cassette cogs are tight and not moving at all.
I am attaching some pictures for a better understanding, and I hope this post will help anybody else who had similar problems with this cassette.
Fingers crossed it will work for you, who are reading this
