The updated SRAM GX Eagle mech
I had an early SRAM GX Eagle mech that died when the chain jumped and jammed between the cage and the jockey wheel. This replacement is the new, improved version with a ridge on the jockey wheel to prevent this happening. Best price on the internet too!

Cheap but rock!
This rear derailleur is the cheap solution for using 12speed, but is a good solution!

Amazing service, great value
Quick delivery from Netherlands to UK. It was hard to believe the price, so I was worried it would be the old model of the GX Eagle deralieur, but it was the latest model and I couldn't be happier abut the whole purchase

Great rear mech
Bought this as an upgrade to my sram SX rear mech along with the GX shifter. I recently bought the GX 12 speed cassette aswell so aside form the crank arms I’m fully running the GX system now and I’m extremely happy with the set up. The rear mech itself is noticeably smoother when shifting in comparison to the SX model.

Quality,precise shifting for a bargain price
Shifts flawlessly so far, easily equivalent to Shimano XT I’ve previously ran. These guys are selling for a steel currently too and with super quick delivery, couldn’t ask for more.

Great upgrade from sx
Upgraded from sx as I managed to bend it out on the trail. Easy set up, feels much more robust as it’s more aluminium than plastic. Perfect shifting so far!

Good Solid piece of kit
Bought to replace a four year old X01. Easy to set up and so far is proving very accurate and reliable in use.

Does what it needs to well
Precise changes, no slop or vagueness. Weighs a few grams more than higher specification models but is a fraction of the price, which is good since I'm replacing a damaged one as the result of clipping a tree stump. Thought I'd take the opportunity to go for the 52T so when my 3rd chain wears out and my cassette is due for replacement I can get a slightly wider gear range.

Simply the best
I bought this to replace my NX on my Ghost ebike which was constantly needing attention. Really easy to fit even for someone like me with very limited knowledge in the mechanics side of things and it's been on the trigger every gear change. Smooth and reliable with a classy look.
5 / 5
Good budget option
Got this to replace my SX shifter which wasn't shifting right - the GX is a big improvement and the newest version here is a great price for GX. Haven't had it long by I've used it for 6 or 7 muddy rides and shifting is still excellent.

Excellent 12 speed derailleur
I managed to break my original Sram GX derailleur (totally my fault). In total despair, I ordered a replacement one on Tuesday night. Mantel managed to ship it on Wednesday morning and I received the derailleur 2 days later, in Sweden. Mantel deserves also 5 stars for its excellent service :) Now about the derailleur itself. This is an excellent and affordable 12 speed derailleur. it shifts up and down super quickly and, if properly adjusted, speeds will never jump from one cog to the other. It feels even faster and more precise than the previous GX version I had. With the longer cage this one can also drive the newer cassettes with a 52 teeth cog. Installation and adjustment is easy. There is even an adjustment gauge on the box, to precisely set the B-screw. As I had no clue on how to use it, i downloaded the PDF manual from Sram site. This is actually simple and it's perfect to fine tune the derailleur. Coupled with a new XX1 chain my transmission is completely quiet with fast and precise shifting.

Better than Amazon
Everything was perfect, in time delivery, very fast from the netherlands, mantis did a great Job. The product, just awesome, it's the gx derailleur. I guess it's the model from 2020, model-id RD-GX-1-B2 with a bandwith of 520% and it works properly with the 52t cassette.

Great product from a superb supplier!
I was finding it almost impossible to find a GX Eagle derailleur in stock anywhere, until I looked at Mantel! Not only in stock, but at a good price & dispatched the same day! A great product from a superb supplier! Mantel will definitely be the top of my list when looking for a great components deal next time!

Complete result!
Having put up with poor indexing and constant mech adjustments for a year, I decided to upgrade to the GX derailleur. This product far outweighs my expectations and cured the issues instantly. I complimented the new mech with a new GX chain as well and and delighted with the result. Mantel were outstanding in price and delivery.

Brilliant product, good value
I upgraded from the nx. I am very impressed with the Gx in comparison. It is much smoother changing gears and alot quieter. Very pleased with it. The delivery was really quick and I didn't have to wait around for the shop to order it in which is a massive bonus at the moment.

High-level change at low price
A whole other world compared to the NX: much more precise mechanism and pulleys. More solid material. Coming from the use of its younger brother, one notices the elimination of pulley bearing play.

Best value for money in my opinion. Fitted myself after my existing NX derailleur broke and was not available. Integrates seamlessly with the rest of the NX group and shifts better than NX.

Fine derailleur. Does what it is supposed to do. In terms of maintenance and service life more durable than e.g. NX. Good value for money.

Choice, availability and pricing
Following the breakage of my previous GX (a nice stone had the brilliant idea of getting stuck in it, shearing it off at the fixing screw), I needed a new one for a planned outing. MANTEL was the only one to have it in stock, and at a fairly reasonable price. Delivered in 3 days to the relay point (order placed on a Sunday evening).

easy to adjust
Well-packaged and easy to install, this derailleur's only drawback is its price. Note that there are no paper instructions and that you have to get them from the SRAM website. My old derailleur (same model) had taken a shock which made it impossible to adjust the gears. On the new one, this adjustment was very easy and all the gears shift perfectly.

It keeps what it promises
Great product discount from sram and lo and behold it delivers what it promises. Fast, precise and quiet shifting. More I do not expect from a schaltwerk. In addition, it fits together with other cassettes from the eagle series, so can be combined

High quality for relatively low price!
Who 28g extra weight compared to the XX1 rear derailleur does not bother, which makes no mistake in buying the GX rear derailleur. It is identical in construction with the XX1 component, it differs only in the material use (aluminum instead of carbon). I am thrilled by the switching behavior, is the premium variant in nothing after.

Value for money and outstanding performance
Following continuous struggles in adjusting the previous 12-speed (10-50) Sram Eagle SX rear derailleur, and its continuous chain hopping between sprockets, I decided to purchase the GX version. Installed in 10 minutes and adjusted in 15 minutes, thanks to the new DIMA provided to adjust the distance between the pulleys and sprockets. It now shifts every gear perfectly, is super strong thanks to being all aluminum with PVC pulleys, costs half as much as the infamous XO1 and above while keeping the quality gap low. Top shipping: ordered Sunday morning and received on Wednesday (in Liguria). Great packaging to keep the product intact
