The **SRAM 00.2518.065.010 AXS Flattop Chain (12/13 Speed, 114 Links)** is a high-performance, precision-engineered drivetrain component designed to deliver seamless shifting and unmatched durability for modern mountain bikes and e-bikes equipped with SRAM s AXS (Axle Symmetric eXperience) electronic shifting system. Crafted from a proprietary blend of high-grade steel, this chain features a **12/13-speed compatibility**, allowing it to seamlessly integrate with SRAM s latest NX Eagle or XX Eagle drivetrains, which offer an expanded range of gear ratios for tackling everything from aggressive descents to efficient climbs. The **114-link length** ensures optimal chain tension and alignment, reducing the risk of derailleur hanger wear and improving overall shifting consistency, whether you're navigating technical singletrack or cruising on a gravel path.
What sets this chain apart is its **Flattop design**, which is engineered to work exclusively with SRAM s AXS electronic shifting system, eliminating the need for a traditional derailleur pulley. Instead, the chain s unique profile and precise spacing are synchronized with the AXS controller and shift cables, enabling **instantaneous, cable-free shifting** with the push of a button on your handlebar. This not only enhances the riding experience by eliminating mechanical lag but also reduces maintenance no more cable stretching, lubrication, or derailleur adjustments. The chain s **optimized pin spacing** and **laser-welded construction** ensure smooth operation, minimizing chain slap and extending the life of your cassette and chainrings.
Built to withstand the rigors of off-road riding, this chain is **hardened and treated for corrosion resistance**, making it ideal for use in wet or dusty conditions where traditional chains might suffer from premature wear. The **AXS-specific design** also incorporates subtle refinements in link geometry to minimize friction, which translates to better efficiency and reduced energy loss during pedaling. Whether paired with a **NX Eagle** setup for a balanced, all-mountain performance or an **XX Eagle** configuration for extreme performance demands, this chain ensures that every shift is precise, every gear transition is seamless, and every ride is optimized for speed and control.
For riders who demand the latest in electronic shifting technology without compromising on reliability, the **SRAM 00.2518.065.010 AXS Flattop Chain** represents the pinnacle of modern drivetrain innovation combining the precision of AXS electronics with the rugged durability of SRAM s engineering expertise. It s not just a chain; it s a critical link in a system designed to push the boundaries of what s possible on two wheels.
The SRAM 00.2518.065.010 AXS Flattop Chain (12/13-speed, 114 links) is a high-end, electronic-shifting compatible chain designed for modern drivetrains. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
### Pros:1. **AXS Compatibility**: This chain is specifically designed for SRAM s AXS (Axsys) electronic shifting system, ensuring seamless integration with AXS derailleurs and shifters. AXS provides precise, wireless shifting with minimal lag, enhancing the riding experience.
2. **Durability and Performance**: SRAM chains are known for their robustness, especially in high-end models like this one. The 12/13-speed compatibility means it can be used across a wide range of modern SRAM drivetrains, including the GX, Force, and Red models. The flattop design is also less prone to derailment compared to traditional roller chains, making it ideal for aggressive riding styles.
3. **Lightweight**: The chain is relatively lightweight for its class, which contributes to better power transfer and overall drivetrain efficiency. This is particularly beneficial for climbers and riders who prioritize weight savings.
4. **Compatibility with Wide-Range Groupsets**: The 114-link length is optimized for wide-range drivetrains (e.g., 1x12 or 1x13 setups) that require extra chain length to accommodate large cog ranges. This makes it a versatile choice for riders using compact or sub-compact cranksets with extended chainstays.
5. **Low Maintenance**: SRAM chains are engineered to reduce wear and tear on other drivetrain components, such as derailleurs and cassettes. The AXS system also reduces mechanical stress on the chain, potentially extending the lifespan of the entire drivetrain.
6. **Future-Proofing**: With 13-speed compatibility, this chain can accommodate future SRAM drivetrain updates, such as wider-range cassettes or new AXS models, without requiring an immediate upgrade.
7. **Precision Engineering**: SRAM s attention to detail in their chains ensures consistent shifting performance and reduced chain stretch over time, which is critical for electronic shifting systems that rely on precise chain positioning.

### Cons:1. **Cost**: This is a high-end chain, and the price reflects its specialized design for AXS systems. For casual riders or those on a tight budget, the cost may not justify the investment, especially if they are not using other AXS components.
2. **Limited Use Outside AXS**: While the chain is compatible with 12/13-speed SRAM drivetrains, it is not designed for mechanical shifting systems. If you plan to switch to a non-AXS drivetrain in the future, you may need to replace the chain, adding to long-term costs.
3. **Chain Wear and Replacement**: Like all chains, this one will wear out over time and will eventually need replacement. The wear rate depends on riding conditions, maintenance, and usage intensity. Frequent riding on rough terrain or in wet conditions can accelerate wear.
4. **Compatibility with Non-SRAM Components**: While the chain is compatible with most 12/13-speed SRAM components, there may be minor issues when paired with non-SRAM parts (e.g., Shimano or Campagnolo). For example, some Shimano AXS derailleurs may not shift as smoothly with SRAM chains, though this is generally rare.
5. **Specialized Maintenance**: AXS systems require proper maintenance to ensure optimal performance. This includes keeping the chain clean, checking for wear, and ensuring the AXS battery is charged. Neglecting maintenance can lead to shifting issues or premature wear.
6. **Chain Length Limitations**: The 114-link length is ideal for wide-range setups but may not be suitable for standard-range drivetrains or setups with very short chainstays. Riders with unconventional setups may need to adjust or replace the chain to match their specific requirements.
7. **Environmental Sensitivity**: Like all chains, this one is sensitive to dirt, moisture, and corrosion. Riding in harsh conditions without proper cleaning and lubrication can reduce its lifespan and performance.

### Conclusion:The SRAM 00.2518.065.010 AXS Flattop Chain is an excellent choice for riders invested in SRAM s AXS electronic shifting system. Its compatibility with 12/13-speed drivetrains, durability, and precision engineering make it a strong option for those who prioritize performance, reliability, and future-proofing. However, its high cost and specialized nature may not be suitable for everyone, particularly casual riders or those not using other AXS components. Additionally, the need for proper maintenance and potential compatibility issues with non-SRAM parts should be considered.
If you are already using or planning to use SRAM s AXS system and need a chain for a wide-range drivetrain, this is a highly recommended choice. For riders on a budget or those using mechanical shifting systems, a more affordable or universally compatible chain may be a better fit.
