## Description

desertcart.com : SRAM GX Type 2.1 10-Speed Long Cage Rear Derailleur Black : Sports & Outdoors

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.
Review: Great replacement for the Sram RD-X9 - Installation was not easy sent it to bike shop, they have the tools and knowledge. I crunched my RD-X9 on a rock. This was a great replacement for my 10 speed fat bike. I would recommend. I have only ridden it about 8 times but no shifting issues. Durability, they hang down asking to be knocked off but, reasonable priced replacement for the x9. Would recommend for the average bicycler for a replacement on a 9/10 speed, mine is 10 speed.

## 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.

### ⭐⭐⭐⭐⭐ Cheap, functional derailleur with automatic clutch provides reliable shifting and reduces chain-drop
*by G***I on December 4, 2019*

So far I've used it for a few rides and it has worked well, definitely better than my old-school (2011?) SRAM x0. I bought it because my current derailleur doesn't have a clutch and suffered from chain slap and frequent chain-drops on the downhill. This derailleur has significantly reduced the number of chain drops and made the downhill somewhat quieter. Installed the same as any typical derailleur. Shifts reliably. I think it's a really good value.
