I need to determine if it will fit my current 6 speed bike and axel** A: The width from bearing side to side is 350 mm, which equates to 1 and 3/8 inch. the inner side does have threads on the inside of it. Some come without threads **Q: Will it work on my 12-speed Schwinn Ranger?** A: No! This is a 7 speed freewheel. Don't think it's interchangable with a 12 speed. You would need different derailer, different shifter, probably spacers, etc. **Q: What is the total width of this freewheel?** A: Maybe just a touch over 1 1/4" **Q: Ordered this product and never received the part. Contacted the company and received a message saying that I’m not eligible for a refund?** A: You can make a dispute with the company that released your payment and ask for a refund, paypal and cc will get your money back if you forward a dispute ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality replacement part *by on Reviewed in the United States July 10, 2026* I neglected to do maintenance on my bike and the chain was very worn. As a result, when I replaced the chain, I started slipping on certain gears. Once I bought this part and installed it, my issue was resolved. It is the exact same part that I am replacing, which was good. Inexpensive and good quality material. Installation was easy once I was done struggling to remove the old one. ### ⭐⭐⭐⭐⭐ Very good Shimano Sprocket *by on Reviewed in the United States May 8, 2026* Excellent Shimano sprocket! The part turned out to be original and very high quality. Installation was easy, everything fit perfectly, and the bike runs smoothly now. You can immediately feel the difference in quality compared to cheap copies. Very satisfied with this purchase and definitely recommend it! ### ⭐⭐⭐⭐⭐ Great replacement, easier to install than I expected. *by on Reviewed in the United States May 5, 2026* This saved my bike. I thought I would have to buy a whole wheel, or rim, to replace my broken sprocket. I stumbled across a video one day of someone who ordered this replacement, and showed how easy it was to replace, so I figured I would give it a shot. I was pleasantly surprised how easy it was to do the work myself. It fit perfectly, and was an exact replacement for my original, just matching the photos on the listing. It was much faster to swap out the broken part than I expected. Once installed, the bike shifted and operated like original. ## Frequently Bought Together - SHIMANO Sprocket 7-Speed MF-TZ500 Screw Ring 7 Speed Sprocket Bicycle Freewheel. - PARK TOOL FR-1.3 Freewheel Remover Shimano Uniglide Tool,Black - Quacc Bicycle Freewheel Remover Freewheel Removal Tool Compatible with Shimano Sunrace Sram Dnp --- ## 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.jp/products/172395127-sprocket-7-speed-mf-tz500-screw-ring-7-speed-sprocket](https://www.desertcart.jp/products/172395127-sprocket-7-speed-mf-tz500-screw-ring-7-speed-sprocket) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
