Review: Great product for great price. - Super fast delivery. Great quality. As described. Took me 15 min to install. Another 10 min to adjust. After that I took a 5 mile ride and it worked without any problems. Highly recommend for a budget derailleur. Thanks Review: Significantly better than a Tourney - My ebikes came stome with a Shimano Tourney and while it was an alright derailer it didn't shift the smoothest even when new and it made a lot of sound. Last week I ran over a log on the trail and bent the derailer so figured I would see what $40 bucks would get me. Wow is all I can say this derailer shifts so smooth and it's quiet as well. Install took me 10 min and getting it indexed took a other 10 min. I like this so much I just ordered 3 more to replace the tourneys on my wife's and kids bikes as well ## Features - 100 - Shimano Acera Rear derailleur compatible with all Shimano 7 & 8 Speed shifters.

I have a schwinn high timber 2.6 26" bike** A: No absolutely not check and make sure your part is same size and gear ratio. **Q: Is this model a "long cage" ?** A: It is, but that is not necessarily helpful. It's always best to match the derailleur (or mech as they say across the pond) to the rear cassette. **Q: is this considered a long or short derailleur** A: I'm not for sure,but the cog wheels are larger ones,some derailleurs have the smaller cog wheels,I would consider those longer,so I'm assuming this is the short one. **Q: Does Shimano Acera m360 have a b-tension screw?** A: google images "Shimano Acera m360 b-tension screw" I think it does. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product for great price. *by R***. on May 4, 2023* Super fast delivery.

The high/low adjustment allow precision limiting to keep the chain where it belongs. ## Frequently Bought Together - Shimano Acera Rear Derailleur RD-M360 7/8S Black by Shimano - Shimano HG40 116 W/CL Chain - Grey, 6/7/8 Speed - SHIMANO CS-HG50 8-Speed Cassette --- ## 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.co.uk/products/45274268-black-acera-rear-derailleur-rd-m360](https://www.desertcart.co.uk/products/45274268-black-acera-rear-derailleur-rd-m360) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
