You can imagine how frustrating it is to receive the same quality on another brand new product. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Works with Razor MX650 *by T***L on Reviewed in the United States on September 3, 2020* It needed a bit of disassembly for my older MX 650. Basically, you don't use the inner flywheel portion. Remove the for allen bolts and match that up to where the old one mounted. It fits a new chain perfectly. If you're replacing this you should probably get a new chain as well. --- ## 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.sn/products/140598144-alveytech-rear-sprocket-freewheel-and-chain-plate-guides-for-razor](https://www.desertcart.sn/products/140598144-alveytech-rear-sprocket-freewheel-and-chain-plate-guides-for-razor) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
