I have used mine with a SRAM 12 speed cassette for the past 1.5 years. Works very well. **Q: Work for 2022 poligon sisuk T8?** A: I have a 2021 but I don’t think there are any differences. That said, yes, it did work for me. I also had a bent hanger, so I had to address that as well. **Q: Is it clutched?** A: The clutch is the worst part. It requires service about once a month. If you bought this already, and if you see your chain go slack on a ride, turn off the clutch, and it works as a non-clutch derailleur. Good enough to limp home, but you will suffer chain slaps and maybe chain drops. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top quality slx derailer. *by M***Y on June 27, 2026* Works great.
