Definitely and advanced install, but do-able (needed to find the manual on Shimano’s site, google “DM-M8050-08-ENG”). Had to change my chain length and mess with the b screw/limits to keep it from rubbing. It’s all aluminum, so should be durable. If I hate it I’ll lower my review. So far I’m not really sure if it’s worth it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/202458378-kcnc-sxt-mountain-mtb-bicycle-bike-rear-derailleur-oversized-pulley](https://www.desertcart.tn/products/202458378-kcnc-sxt-mountain-mtb-bicycle-bike-rear-derailleur-oversized-pulley) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-17*
