- 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.
- 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.
Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette.
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.

"Essentially a simpler and slightly heavier version of X1, you get the same performance at a fraction of the price. This is the one we’ve been waiting for."
The German Enduro Magazine published a long-term test about the SRAM 1x11 drivetrain. With each of these group sets having ticked off several thousand kilometers on their test fleet, they thought it was time to see how they were faring. The 1x11 drivetrains have been out on all terrains for serious testing - from the Bavarian mountains to the flowing trails around Stuttgart, and not forgetting the filthy wet lines of Scotland
"In the case of the 1X11 group set that we tested we consider it a game changer. It is a prime example of trickle down technology. SRAM’s 1X11 drivetrain started out as something that not many could afford but everyone lusted over. Now it almost doesn’t make sense not to run it. Most consumers love the idea of being liberated from the front derailleur. Less cables, less stuff on your bar, less noise and less to think about. It’s also incredibly durable. In 6 months of aggressive riding in mixed conditions, we still haven’t worn out the chain or cassette."
"That’s really the reason why this group is such a home run – even the best cassette and derailleur adapters can’t touch the shifting performance of a dedicated wide range group like GX 1.... but if given the choice between adapters and a full group? This wins all day."
"We say it a lot, but right now is a really good time to be a mountain biker. SRAM’s excellent GX drivetrain is just further proof for that claim."
"When SRAM released its original XX1 drivetrain, it made a 1x drivetrain a realistic alternative to riders who needed a wide gear range...But their new GX drivetrain offers similar levels of performance to SRAM’s high end 1x group sets, but retails for nearly half the price."
"Last year, Dirt Rag Editor-in-Chief Mike Cushionbury awarded SRAM’s X01 drivetrain his Editor’s Choice honors because it offered similar performance to the flagship XX1 group at a reduced cost. With GX1, SRAM has again significantly cut the price of entry to 1×11 ownership."
"If I were building a bike or planning to buy a new one, I’d be targeting GX 1×11 for certain. This is the pinnacle of the current performance-to-value ratio right now."
"GX shifting felt clean and responded to the same light, quick touch as its premium counterparts."
"Changing gears on the trail should always be such a nonissue, and now it can be for more of us."
"Plenty of abuse has been heaped upon that drivetrain: grime and snow didn’t affect the shifting; Whistler bike park’s infamous mud was simply shrugged off; imperfect shifts didn’t expose a lack of stiffness; and I haven’t had to monkey around with it to keep the shifting precise and smooth. It’s almost embarrassing how well the drivetrain is still working despite a lack of maintenance, other than infrequent de-greasing and cleaning."
"The SRAM GX group set brings the same high-performance shifting and wide-range cassettes to a price point that make it affordable for the average rider. GX shares the same reliable function as its more expensive siblings, with only a small increase in weight...it’s near perfect. 1x drivetrains are simple, efficient, and the perfect solution for trail riding; for the rider looking for performance on a budget, the new SRAM GX is a revelation.
"This season, I’ve ridden both 1x GX and Shimano XTR extensively and I’m going to have to be honest here and say that, in my experience, the budget-priced GX kit simply outperforms the other guys top-shelf kit hands-down. Shifting accuracy, speed and feel are far and away better in every respect. I think it’s fair to say that if you want to get a 1x drivetrain, stick with the originals, folks."
