The first broke after 9 months (after applying clutch). The second lasted 4 months before wrapping up around the Cassette (again after using the clutch). So I decided to change to the SRAM. Well worth it! The change is smoother and there is clearly more tolerance in the mechanism. I thoroughly recommend fitting one of these derailleurs. Review: Was apprehensive on ordering this after reading bad reviews. I usually go for X9 or XO - Was apprehensive on ordering this after reading bad reviews. I usually go for X9 or XO.....but finding long cage 10 speed 2.1 SRAM derailleurs or reasonable price is getting harder & harder, so I pulled the trigger on this. It actually turned out well. Fitting and setting up went without issue.....no stripped screws. Shifting is spot on. Early days yet, but will report back if it fails within the next year. ## Features - Exact Actuation technology - Precise and dependable 10-speed performance focused chassis design - 36-Tooth cassette capable cage - Model number: 007518080000 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00V8RZ9SW | | Batteries included? | No | | Best Sellers Rank | 68,080 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 62 in Bike Rear Dérailleurs | | Bike type | mountain | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (697) | | Date First Available | 26 Mar. 2015 | | Department | Unisex | | Global Trade Identification Number | 00710845771835 | | Included components | Rear Deraille | | Is discontinued by manufacturer | No | | Item model number | 00.7518.080.000 | | Manufacturer | SRAM | | Material type | Plastic | | Number of items | 1 | | Number of pieces | 1 | | Power source | ac | | Product dimensions | 17.3L x 16.6W x 8.1H centimetres | | Seasons | continuity 2015 | | Size | One Size | | Sport | Cycling | | Style | Long | | UPC | 757183591480 710845771835 784427964175 | | Usage | cycling | | Weight | 0.4 Kilograms | ## Product Details - **Brand:** SRAM - **Colour:** Black - **Item weight:** 157 Grams - **Material:** Plastic - **Mounting type:** Braze-On Mount ## Images ![MTB Gx Type 2.1 Long Cage Rear Derailleur - Black, 10-Speed - Image 1](https://m.media-amazon.com/images/I/617d3tl81RL.jpg) ## Questions & Answers **Q: What size should I use for a 36 -11 casette?** A: Forgive me, but you are asking the wrong question.The cage size is controlled by the maximum amount of slack chain created by the combination of chain rings AND cassette. This is called "Chain Wrap".To formula for chain wrap is (Big Chain Ring - Small Chain Ring) + (Big cassette Cog - Small Cassette Cog). So if you are using a compact double chain ring (50-34) and a 11-36 cassette the numbers work out to (50 minus 34) + (36 minus 11) or 16 + 25 = 41. This means that if you shift from a big-big combination to a small-small combination, your derailleur has to be able to handle 41 teeth of loose chain, which calls for a long cage. On my bike a have a single 40 tooth chain ring and a 11-42 cassette so the chain wrap works out to (40 - 40) + (42 - 11) = 0 + 31 = 31. So even though I have a huge cassette I only need a medium cage because I have no front derailleur to create more chain wrap.Hope that helps. **Q: what is short, medium.long cage?** A: It has to do with chain wrap capacity. Small=30t Chainwrap Capacity, Medium=35t, Long=47t. The wrap is just the difference between the number of chain ring teeth plus the difference between the cog teeth. For example a 53/39 with a 12-25 cassette requires 14 + 13 = 27 teeth of wrap capacity needed from the RD. **Q: Will this work with Shimano Ultegra shifter** A: No, actuation will only work with sram.... The good news is that it will work with both sram 10 speed road and Mtb... Unlike the newer 11 speeds witch are road or mtb specific. **Q: Can this be used with a shimano 11/42 cassette ?** A: I used it with a sunrace 11-42 cassette but I needed a longer b tension screw(which was not provided) so you will likely run into the same issue. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I thoroughly recommend fitting one of these derailleurs *by M***. on 15 March 2018* Previously I had 2 XT derailleurs of the other make both of the same model.

Nearly bloody killed my self at Hamsterly forest on a blue trail warmup as the derailer collapsed into the rear cassette.
