by Maxime B. on 08.06.2025 item: black/9-50

Quality sure is there, it looks good, feels good. The gear changes are not as quiet as with cassettes specially designed for the drivetrain. I would say it is brutal, yet it is efficient.
Really light.

Only downside : installation process. I thought it was pretty easy, but it actually was not !
DO NOT put too much grease, the tolerance are extremely tight. So if you put too much of it you won't be able to mount it.
Even by removing the grease, I has to file down the hole for the last bolt in order to get it properly mounted ! Hours lost.

I'd say tolerances need to be checked by e-thirteen.
