Product ReviewsSRAM GX Type 2.1 10 Speed Long Cage Rear Derailleur - Black

SRAM GX Type 2.1 perfect for 1x10 setup

SRAM sells specific derailleurs for 1x and 2x / 3x setups, but they are not mutually exclusive. I'm using this RD on a 1x10 setup along with a Sunrace 11-42 cassette. It's a tight squeeze, but it can be done. Shifting is excellent with the GX 10 speed shifter. This RD is perfect for almost everyone, except perhaps the most demanding of cyclists.Read full review...

GX Derailleur VS X5

I wanted to up grade to a better newer model, it cost me more. The GX looks great and I think for the price is not bad if you already are planning to up grade to this derailleur With shifter for ten speed. My X5 shifter was working ok, so I thought with the X5 Derailleur but when I installed the GX Derailleur I found I could not get proper adjustment out of it. At this time I'm waiting for my new GX 10 speed shifter see if that will work good.
When I install my X5 Derailleur with shifter everything work just find, It seems I can only get 9 gear with the GX Derailleur this is why I have order the new shifter. Also in the center gears it dose not quite shift as smooth as my X5 system no matter what I have tried to do.
I hope this helps you decide, I can't say how it will work with the correct shifter because at this time I do not have it. Read full review...

Works just like it should.

The good:
Quick and precise shifting, stable chain handling, and easy to use.

The bad:
The cage was stuck in place out of the box and it took a lot of force to free it.

The expected:
This rear mech is used on my street bike and so I added a barrel adjuster to the shift cable.
Very high quality piece of kit.Read full review...

No more chain slap

GX rear derailleur is compatible with older SRAM Exact Actuation shifters and has a clutch to stop chain slap and dropped chains. It works well, easy to set up, and even black matte finish is pleasing to look at. I don't see a reason to spend more $$ on a higher end derailleur - GX level works perfectly.Read full review...

great upgrade

I upgraded from a Shimano Sora drivetrain to a SRAM drivetrain on my Salsa Vaya 3. Huge improvement. Got to a lower gear inch that needed for touring in steep country, and shifting is so much crisper. Love it. Anyway, a nice rear derailleur that works with the rest of the MTB-setup. I used APEX shifters, X5 crank, X7 front derailleur. All together was a decent price for big upgrade. No miles on it yet but so far beautiful. But based on my other bikes with similar components, I'll enjoy a lot of miles from this.Read full review...

No more chain noise on the trail.

This replaced my non-clutch rear derailleur and it was a great upgrade. No more noisy chain slap while bombing a trail. Shifts are smoother and faster than before. Can now change gears on heavy climbs when I could not before. If you are on the fence about switching, do and never look back.Read full review...

A very good value. Works great.

I can't compare this to other rear derailleurs since I haven't set them up before. However once installed, it works great. The cable routing is very smart as well as the clutch lock. There were no instructions included, which added 30 minutes of internet searching for instructions.Read full review...

10 speed long cage shifter .

Just what I needed. 10 speed bike components are becoming hard to find. I have an older 10 bike. This works perfectly!

Works great

Initially I thought it's broken - the cage did not move, but finally I had to add more effort to get it work. The cage clutch works as announced so no any chain contacts with frame on rough surfaces.
