SRAM GX Type 2.1 Rear Derailleur - 10-speed

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.

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.

SRAM GX 10 speed derailleur works as advertised. Arrived early. Perfect fit. Replacement of my 2013 X9 derailleur on my Stumpjumper Comp Evo mountain bike.

Took the plunge and went to a 1x system. Really quality bit of gear, upped my shifting game 1000%. 4 stars out of box. Once it was adjusted properly and i fixed /modded the Bscrew, it became 5 stars performance for a 3 star price point. Make sure you pair this with all GX components and it will work like clockwork, freakishly shifting like a... well F1 machine... I used an SRAM GX10 derailer, gx10 shifter, and gx10 cartridge, with a shimano M361 crankset (had to penny pinch) and steel sprocket, that worked well but dropped the chain 3 times in a week of riding soo... now have a race face 36frnt chainring. haven't dropped the chain since . All in all, I think the SRAM GX10 is a spectacular budget performance/racing derailer.

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.

Sept. 19, 2018 - Almost a year to the date since I put this on me 2016 Trek EX8. Put 1176 miles of rough single track thru the woods of Patapsco State Park in Maryland. Lots of mud and wet. The main thing that killed this derailleur where the rocks and sticks bouncing up from the trail. It was a large rock on a crazy downhill that finally did it it. Once a derailleur is bent itr will never shift smooth. I went in full and upgraded the whole system to SRAM GX 12 speed.

Ordered this to use with my Rival shifters so I can use a bigger cassette for climbing. I was worried initially because of the bad reviews, but so far I haven't a single problem. Springs are good. No wobbly linkages. B tension screw and plate are working. Hi and Lo limit screws have no problems. Very easy to install and adjust. I am still waiting for my new cassette (11-36) and new chain, but I predict that there will be no problem adjusting the RD when I swap parts. Can't comment about durability yet, but so far the RD looks durable.

I replaced an older X7 rear derailleur with this GX. I wish I would have purchased Shimano... The quality of this GX is not as good as my older X7. The anchor plate is very loose on the attaching bolt which caused the B-Screw to slip by it when adjusting the B-Screw. As this happened t he B-Screw was damaged, then damaged the derailleur when backing the B-Screw back out. Second, the spring tension in the derailleur is weak, causing shifting issues when shifting to the smaller cogs. If the B-Screw wasn't damaged I would return it, but instead I have a new derailleur that is worse than my old X7. So much for "Upgrading".

Günstiges und sehr gutes Schaltwerk. Die hervorragend gute Kettenspannung sorgt im Gelände für Ruhe und dafür, dass der Rahmen nicht durch die Einschläge der Kette zerkratzt. Die Schaltleistung ist sehr gut. Die SRAM typische Arretierung hilft bei Wartungsarbeiten.

Previously I had 2 XT derailleurs of the other make both of the same model. 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.

Lo adquirí para sustituir un Shimano XT de 9v y poner 10v. Si lo combinas con el shitfer GX de SRAM va perfecto, sube piños y baja de forma exacta. Ya veremos con mas tiempo de uso, pero por el momento va genial.

Was exactly what was described and very fast postage

Perfect replacement for a broken derailleur. Great shifting, easy setup.
