Shifting performance is great, short and precise. Not cheap but worth it. ### ⭐⭐⭐⭐⭐ A lovely addition to a cycle *by P***Y on 16 November 2024* It's well made, nice and compact and although the specs say that the biggest rear cog it can handle is a 36T it can actually take a larger 42T cog especially on a hardtail bike (due to a lack of suspension induced chain growth). I am running this derailleur on a 14-42T rear gearset. Another thing that can be done, either by use of a spacer or by drilling a hole, is to make this ten speed derailleur work with a 9 speed cassette/freewheel. I currently have it working as a 9 speed derailleur. It's a lovely derailleur and it's compact size makes it ideal for use on small wheeled bikes such as folding bikes. I hope Shimano continues to produce it. ## Frequently Bought Together - Shimano RD-M640 Zee Shadow Plus 10 Speed Rear Derailleur - Shimano SL-M640 Zee 10 Speed Shifter - Shimano HG50 10 Speed Mountain Bike Cassette 11-36T --- ## 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.gr/products/291490769-shimano-rd-m640-zee-shadow-plus-10-speed-rear-derailleur](https://www.desertcart.gr/products/291490769-shimano-rd-m640-zee-shadow-plus-10-speed-rear-derailleur) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-22*
