Review: A quality derailleur - The SRAM 10 speed derailleur in a long cage was just what I needed for my custom build. Very easy to install and adjust, clean crisp shift between gears. Fit my bike like a glove, Very smooth and an overall great value for the money you just can’t beat it. Review: Best bang for your multi-speed bicycle buck! - IMO, this is the best derailleur you can buy in this price range. It is kind of odd that over the decades bicycles have gone from 3 speed "English" bikes to 24 speed bikes. What people are noticing is when you have 24 different speed combinations and ratios, a lot of them are so close together that they more or less get duplicated, so you really don't have 24 "useable" speed combinations. So, it makes sense to a lot of folks that a single chainring turning a 10 speed wide ratio cassette is a better and simpler system, especially since you now only have one shifter to worry about, and the cassettes come with customizable cog ratios. 10 cog cassettes are usually a little longer than 5, 6, 7 and 8 cog cassettes, so it is important to have a sturdy and dependable derailleur. ## Features - Exact Actuation technology eliminates slop and shifting variation - Features a long cage with a chain wrap capacity of 47 for versatile gearing. - Includes a roller bearing clutch in the pulley cage pivot to enhance chain control. - Equipped with a Cage Lock mechanism to simplify wheel removal and installation. - Fits rear derailleur mounts with a 10x1 standard and handles largest cogs up to 36 teeth. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00V8RZ9SW | | Best Sellers Rank | #88,081 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #37 in Rear Bike Derailleurs | | Brand | SRAM | | Brand Name | SRAM | | Case Material Type | Aluminium | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 745 Reviews | | Global Trade Identification Number | 00710845771835 | | Included Components | Rear Deraille | | Item Dimensions L x W x H | 12"L x 8"W x 2"H | | Item Highlight | SRAM GX Type 2.1 10-Speed Long Cage Rear Derailleur - Clutch Technology | | Item Type Name | SRAM derailleur gx type 2.1 long cage 10 speed black | | Item Weight | 157 g | | Manufacturer | SRAM | | Manufacturer Part Number | 00.7518.080.000 | | Material | Aluminum | | Material Type | Aluminum | | Model Number | 00.7518.080.000 | | Mount Type | Standard | | Mounting Type | Standard | | Number of Items | 1 | | Number of Teeth | 10 | | Product Dimensions | 12"L x 8"W x 2"H | | UPC | 757183591480 710845771835 784427964175 | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** SRAM - **Color:** Black - **Item Weight:** 157 g - **Material:** Aluminum - **Mounting Type:** Standard ## Images ![GX Type 2.1 Rear Derailleur - 10-speed - Image 1](https://m.media-amazon.com/images/I/61obu8T-BgL.jpg) ![GX Type 2.1 Rear Derailleur - 10-speed - Image 2](https://m.media-amazon.com/images/I/51dcX9YtloL.jpg) ## Available Options This product comes in different **Style** options. ## 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 ### ⭐⭐⭐⭐⭐ A quality derailleur *by D***7 on February 9, 2026* The SRAM 10 speed derailleur in a long cage was just what I needed for my custom build.
