Developed specifically for SRAM 1x, X-Actuation™ keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.

Roller Bearing Clutch™
Roller Bearing Clutch™ rear derailleurs deliver maximum drivetrain stability-even through the most punishing terrain. With Roller Bearing Clutch™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.

Cage Lock™
With Cage Lock™ technology in the rear derailleur, wheel removal and installation-as well as chain installation-becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.

The X-Horizon™ rear derailleur's 'straight parallelogram' design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

SRAM X-Sync™ 1x chain rings provide the highest level of performance and durability. The SRAM X-Sync™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync™ rings are an integral part of the SRAM 1x™ drivetrain.

Save weight and clutter on the bar with MatchMaker. This system holds Avid® levers, a number of SRAM triggers and RockShox PushLoc controls - all with one tidy, light clamp.

With durable Jet™ black finish, the cassette looks as tough as it performs-ride after ride. Jet™ finish provides a higher level of corrosion resistance.

I have previously in my Canondale bike a drivetrain with a SLX I-Spec-B 10Speeds Lever; a SLX 10Speeds rear Derrailler and a Deore 10Speeds Cassete.
My self and I have made the removal of the Shimano's items and the installation of the SRAM GX 1*11- fach Upgrade-Kit. The installation of the new kit was very straight forward, and the tuning of the transmitting was also very straight forward with the reading of the SRAM Manual installation, and if you pay attention to the sounds of the drivetrain when you are trying to tune the derailleur on the 42T cog and on the 10T cog.
After the installation and after some rides what I can say is that it was a huge improvement in terms of shifting. Also the SRAM XD freewheel system based on threads turn out to be much more stiff that shimano's freewheel system (you will notice that when you shift down and make the pedal stroke and ear the sound TRAAAAA, it's so beautiful, it's a sin of work not been wasted).
The SRAM GX also have a button were you press and maintain the derailleur at a fix position that is a very good thing to have when you need to remove or install your wheel.
For this price I consider this option to be much better that installing an independent larger cog (e.g. 42T) or buying a 10Speeds cassette with a 40T ou 42T. For what I have read at webpages there were issues many times with this systems.
Conclusion: If your budget supports the price what I can say is that I would recommend to all of my friends: this 1*11 option; to change to 1*11; and to SRAM XD freewhell system.
