Product description of Sram X-Sync Eagle 104 BCD chainring

Description summary

Upgrade your 1x12 SRAM Eagle drivetrain with the X-Sync 2 104 BCD Chainring. Engineered for extreme chain retention, its aggressive tooth profile securely grips your chain, preventing drops on challenging terrain. Enjoy silent, efficient pedaling and extended drivetrain life thanks to reduced friction and superior mud clearance. Built for MTB durability, this ALU chainring is the ultimate performance boost for any trail

SRAM X-Sync 2 Eagle 104 BCD Chainring | 12-Speed for MTB Cycling

Elevate your mountain biking performance with the genuine SRAM X-Sync 2 Eagle 104 BCD Chainring, the pinnacle of single-ring drivetrain technology. Engineered specifically for the demands of modern MTB Cycling, this chainring is a critical component for any rider seeking flawless chain management, exceptional durability, and the silent, efficient operation that defines the SRAM Eagle ecosystem. Whether you´re upgrading your current 4-arm crankset or replacing a worn component, this chainring ensures your 12-speed drivetrain performs exactly as it was designed—with precision and reliability on every trail.

The core of this chainring´s superior performance lies in its radically effective X-Sync 2 tooth profile. This isn´t just another narrow-wide design; it´s a complete system engineered to work in perfect harmony with the inner and outer links of a SRAM Eagle chain. The result is unparalleled chain retention, giving you the confidence to charge through the roughest rock gardens and technical descents without the fear of a dropped chain. This aggressive tooth design actively grips the chain, providing a secure connection that translates into more efficient power transfer and a more connected feel to your bike.

Beyond its incredible chain retention, the X-Sync 2 design focuses heavily on longevity and performance in real-world conditions. The updated tooth profile is engineered to reduce friction and wear on both the chainring and the chain, significantly extending the life of your drivetrain components. Furthermore, the design features optimized mud-clearing recesses, which actively shed dirt and debris. This ensures consistent performance and quieter operation, even when riding in wet and muddy conditions, preventing chain suck and maintaining smooth pedaling when it matters most. For any rider on a 1x12s setup, this chainring is the key to unlocking a smoother, quieter, and more durable ride.

Key Benefits:

* Unmatched Chain Security: Drastically reduces the risk of dropped chains on rough terrain thanks to the advanced X-Sync 2 Eagle-specific tooth profile.
* Increased Drivetrain Longevity: Engineered to decrease friction and wear, extending the life of both your chainring and your expensive 12-speed Eagle chain.
* Silent and Smooth Operation: The refined tooth shape and chain interface deliver a noticeably quieter and more efficient pedaling experience.
* All-Condition Performance: Excellent mud and debris-shedding capabilities ensure reliable function no matter how challenging the trail conditions get.
* Seamless Integration: Designed as the perfect match for all SRAM Eagle 12-speed drivetrains, guaranteeing optimal shifting and performance.

Original replacement part recommended for mountain biking on flat terrain

2025/11/20

Recomendable MTB en terreno llano

The chainring is exactly as described, a genuine SRAM replacement part. I consider it to be too high a gear ratio for an amateur rider who tackles steep climbs; I only recommend it for people who ride mountain bikes on smooth terrain, gravel, or who are in reasonably good physical shape.

I installed this one in my mtb to avoid using the largest gogs while riding on the pavement. Four teeth more compared to old chainring and i achieve the same speed with tenth gear as earlier i useded the smallest gog which wears quick in long distance riding.

Good quality chainring, absolutely silent. Being steel, it's quite heavy—the 34T weighs about 140g—but it's ideal for use on a full-power ebike. At €13, the price is unbeatable.

Hello, I have a VAE 38T........36 does not exist, you have to go to 34. That´s a lot

Answer of Javier

At top speed if you notice the loss of 4 fewer teeth, but you gain it uphill, it depends on what else you do, whether on the road/greenways or in the mountains. But on the page there are 2 options, 34t and 38t.

Hello, what is the exact reference of this chainring in the 34 tooth version please? Kind regards.

the chainring described to the side is compatible with my sram 12-speed gearbox, given that the product I want to buy, in the characteristics, tells me that it is for 9 speeds. the chain should also be shortened since I currently mount a 34 chainring. thanks

Answer of Marlon

This chain ring is compatible only for 11s or 12s and has wide and narrow tooth as per manufacturer recommended, in my opinion the 9s chain has wider chain so it can fit to this chain ring. The 12s chains are designed to thin chain ring.

Hello, I intend to install it on Shimano cranks to convert a triple chainring to a single chainring. Is this chainring compatible with these 104 BCD cranks?

Answer of Javier

If the spider of the connecting rod is 104 BCD, it has to carry a 104 BCD plate and if you change the 2 washers that the connecting rod has to a single plate, now you will have to leave one for the alignment of the chain with 1 plate

The Drivetrain Upgrader

This cyclist is looking to upgrade their current setup to a modern 1x (single chainring) system or replace a worn-out component on their existing 12-speed drivetrain. They prioritize compatibility, reliability, and tangible performance improvements without overcomplicating their bike's mechanics.

With its 104mm BCD, this chainring is a straightforward upgrade for many common cranksets. It's designed for Sram's 12-speed Eagle drivetrains, ensuring seamless integration. The steel material offers excellent durability and wear life, making it a reliable choice for riders looking to enhance their bike's performance for the long term.

The All-Terrain Trail Rider

This individual enjoys riding a variety of trails, from smooth singletrack to technical, bumpy descents. Their main concern is having a bike that performs reliably in all conditions, allowing them to focus on the ride itself rather than worrying about mechanical issues.

The X-sync technology provides this rider with exceptional riding assurance. The advanced tooth profile holds the chain securely, which is crucial when navigating unpredictable terrain. This focus on chain retention and efficient operation contributes to a quieter, more enjoyable ride, allowing the rider to tackle diverse trails with confidence.

Competitive features

When selecting a chainring, key factors include material, tooth profile, and compatibility with your drivetrain and crankset. The Sram X-sync Eagle 104 Bcd Chainring is engineered for modern 1x drivetrains, focusing on chain retention and durability. In contrast, other options like the Shimano GRX series are tailored for gravel-specific groupsets, while options such as the Shimano Acera are designed for different speed configurations and use cases. The primary distinction often lies in the tooth technology, BCD standard, and intended discipline, whether it's MTB, e-MTB, or gravel.

Where it excels

Features SRAM's X-Sync 2 tooth profile, specifically engineered for superior chain retention on 12-speed systems, which helps prevent chain drops on rough terrain. Constructed from durable steel, making it a reliable choice for high-stress applications like e-MTB and demanding trail riding. Offers broad compatibility by using the common 104 BCD standard, allowing riders to upgrade a wide variety of cranksets to a modern 1x12-speed setup.

Consider alternatives if...

If your setup is a dedicated gravel bike with a Shimano GRX groupset, a GRX-specific chainring like the RX810 would be designed for optimal system integration. For riders using older or more basic drivetrains, such as 7 or 8-speed systems, a more compatible option like the Shimano Acera M361 chainring would be more appropriate. If your crankset requires a Direct Mount interface instead of a 4-bolt 104 BCD, you would need to look at alternatives like the SRAM X-Sync Eagle Direct Mount chainrings.

Verdict

The Sram X-sync Eagle 104 Bcd Chainring is an excellent upgrade for mountain bikers and e-MTB riders looking to enhance their 1x12 drivetrain's performance. Its steel construction provides durability for high-torque use, and the X-Sync 2 technology delivers dependable chain retention. For drivetrains outside of this scope, other specific chainrings would be more suitable.
