I ordered the 31.8 size because my bike has a 28.6 frame size. I also ordered a set of shim spacers and the derailleur works perfectly. It was easy to install and adjust, I just had to buy a chain breaker. This is probably their most budget friendly derailleur but for my old bike, it's all I needed. I love it.I also ordered another one before this. It was for a 34.9 frame. I also ordered a set of shims for this to but it didn't line up right with my smallest sprocket probably because of the larger size difference. Both were good. ### ⭐⭐⭐⭐ My front derailleur broke *by on Reviewed in the United States February 27, 2024* But this one won't work on my bike. I can use it on another. That's the beauty of having a lot of bikes. This is pretty nicely constructed. Maybe I could Mickey Mouse my bike to make this one work I can use it till I get the right derailleur. I only need the large gear. But when I shift into the small gears in the back it pulls off the large gear onto the smaller ones in the front. And I believe if I sit this just for the front large gear it'll stay in place and not cross chain. So that's what I'll do until I get a different style ## Frequently Bought Together - Bicycle Front Derailleur FD-TY300 3 x 6/7 Speed Up/Down Swing, Bike Derailleur 3 Speed with Adjust Clamp Size 31.8mm 34.9mm for Mountain Bike Road Bicycle - Boao Universal Bicycle Transmission Line Bicycle Shift Derailleur Cable and Brake Cable Kit for Mountain Road Bike Repair - Shimano Tourney RD-TY300-SGS 6/7-Speed Mountain Bicycle Rear Derailleur , Black, One Size --- ## 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/624317751-fd-ty300-front-bike-derailleur-for-3x6-7-speed-compatible](https://www.desertcart.tn/products/624317751-fd-ty300-front-bike-derailleur-for-3x6-7-speed-compatible) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-24*
