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. ## Frequently Bought Together - SHIMANO SLX Rd-M7100 Rear Derailleur Black, Sgs, 12-Speed - Shimano SLX CN-M7100 Chain - 12-Speed, 126 Links, Silver --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/448864067-shimano-rd-m7100-slx-rear-derailleur-12spd](https://www.desertcart.com.ar/products/448864067-shimano-rd-m7100-slx-rear-derailleur-12spd) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-09*
