Review SRAM 48/35t Red E1 Groupset Latest Release

The **SRAM 2024 E1 48/35T 125PD Groupset** represents a bold leap forward in mountain bike performance, blending cutting-edge technology with the raw, aggressive spirit of enduro and downhill riding. At its core, this groupset is engineered to deliver unparalleled power transfer, precision, and durability, making it the pinnacle of SRAM s commitment to pushing the boundaries of what s possible on the trail. The **48/35T chainring setup** is a game-changer for riders seeking a balance between climbing efficiency and downhill aggression. The larger 48T front sprocket provides a substantial gear advantage for steep climbs and technical ascents, while the 35T option offers a more aggressive ratio for high-speed descents and aggressive riding, ensuring riders can tackle any terrain with confidence. This duality is further amplified by the **125PD (125mm pitch) cassette**, which replaces the traditional 11-speed 12-50T setup with a wider range of gears spanning from a **12T** for brutal climbs to a **50T** for effortless cruising while maintaining the compact, efficient profile of a 12-speed system. The result is a drivetrain that eliminates the need for a mid-drive motor, offering riders the freedom to focus solely on their riding style without compromising on performance.

The **E1 groupset** is built around SRAM s **eTap AXS wireless electronic shifting system**, which has been refined to deliver even more responsive, precise, and reliable shifting under the most demanding conditions. The **eTap AXS ** version introduces a **dual-mode shifting algorithm**, allowing riders to toggle between **Aggressive** (for quick, decisive shifts) and **Precision** (for smoother, more controlled adjustments) modes, depending on the terrain and riding conditions. This adaptability is further enhanced by the **E1 s integrated battery**, which now features a **longer runtime** and **faster charging capabilities**, ensuring riders can spend more time on the trail and less time worrying about power. The **wireless, remote-controlled shifting** eliminates the need for cable routing, reducing weight and complexity while improving reliability in the harshest environments.

The **derailleur and shifter design** reflects SRAM s relentless focus on durability and performance. The **E1 derailleur** incorporates **reinforced internals** and a **high-strength alloy frame**, making it resistant to the impacts and debris common on downhill and enduro trails. The **shifters** feature an **ergonomic grip** and **quick-release buttons**, allowing for effortless shifting even with gloved hands, while the **haptic feedback** ensures riders know exactly when a shift is complete. The **cassette and chain** are no exception to SRAM s attention to detail. The **125PD cassette** uses **SRAM s proprietary 12-speed pinion design**, which reduces weight while maintaining strength, and the **12-speed chain** is engineered for **longer wear and smoother engagement**, even under heavy loads. The **125mm pitch** also allows for a **wider range of gearing** without the bulk of a traditional 11-speed setup, making it ideal for riders who demand versatility without sacrificing efficiency.

For riders who demand the ultimate in performance, the **E1 groupset** also includes **SRAM s Red eTap AXS ** option, which integrates with the **Red eTap AXS battery pack** for even greater power and range. This setup is perfect for riders who push their bikes to the limit, whether on long enduro races or extreme downhill descents. The **E1 groupset** is not just about shifting; it s about **seamless integration** with the rest of the bike. The **brake system** (when paired with SRAM s **Code R or Code S brakes**) ensures consistent modulation and stopping power, even in wet or muddy conditions, while the **bottom bracket** (when used with SRAM s **XX1 or XX eTap AXS cranksets**) provides a smooth, efficient power transfer. Whether paired with a **hardtail enduro bike** or a **full-suspension downhill rig**, the **E1 48/35T 125PD groupset** delivers a **complete, high-performance solution** that elevates every ride.

In summary, the **SRAM 2024 E1 48/35T 125PD Groupset** is a **monumental advancement** in mountain bike technology, designed for riders who refuse to compromise. It combines **aggressive gearing**, **wireless electronic shifting**, **unmatched durability**, and **seamless integration** to create a groupset that not only keeps up with the demands of modern trail riding but sets a new standard for what s possible. Whether you're a professional racer, a hard-charging enduro rider, or an adventurous trail explorer, the **E1 48/35T 125PD** is the ultimate choice for those who demand the best every time, on every descent.

The SRAM 2024 **48/35T 125mm E1 Groupset** is a high-end, wireless electronic groupset designed for road and gravel cycling. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

**1. Wireless and Lightweight**

The E1 groupset eliminates the need for a traditional cable system, reducing weight and complexity. The wireless design improves aerodynamics and simplifies installation, especially on road bikes where cable routing can be cumbersome.

**2. High Performance and Responsiveness**

SRAM s wireless shifting is known for its smooth and precise operation, with minimal lag. The E1 system uses a wireless transmitter and receiver, which eliminates cable stretch and friction, leading to more consistent shifting performance.

**3. Compatibility with SRAM s E-TAP System**

The E1 groupset integrates seamlessly with SRAM s E-TAP wireless shifting system, which allows for customizable shift maps, group ride connectivity, and even smartphone integration via the **SRAM Power App** or **E-TAP Connect**. This makes it ideal for riders who want advanced features like cadence-based shifting or power-based adjustments.

**4. Durability and Weather Resistance**

SRAM s electronic groupsets are built to withstand harsh conditions. The E1 system is rated for use in wet and dusty environments, making it reliable for gravel, touring, or commuting.

**5. Aesthetic Appeal**

The E1 groupset has a sleek, modern design with a minimalist look, which appeals to riders who prioritize aesthetics alongside performance. The lack of cables also contributes to a cleaner bike appearance.

**6. Future-Proofing**

SRAM continues to update its electronic systems, and the E1 groupset is likely to receive firmware updates that could introduce new features or improvements over time.

**7. Compatibility with a Wide Range of Bikes**

The E1 groupset is designed to work with both road and gravel bikes, offering flexibility for riders who may switch between disciplines.

**8. Reduced Maintenance**

Wireless systems require less maintenance than traditional cable-based drivetrains. There s no need to worry about cable stretch, pinch points, or derailleur alignment issues that can arise with mechanical systems.

---

### **Cons**

**1. High Cost**

Electronic groupsets are significantly more expensive than mechanical alternatives. The SRAM E1 groupset is positioned as a premium offering, which may not be justified for casual riders or those on a tight budget.

**2. Battery Dependency**

The E1 system relies on a battery (typically a small CR2032 or similar) to power the shifting. While the battery life is decent (often lasting several months or even a year with normal use), it adds another component to manage. Riders must remember to replace the battery before it fails, which could happen at an inconvenient time.

**3. Limited Availability of Parts**

Electronic groupsets have a smaller aftermarket support system compared to mechanical drivetrains. If something goes wrong (e.g., a faulty shift lever or derailleur), finding replacement parts or technicians who can repair them may be more difficult.

**4. Potential for Electronic Failure**

Electronic components can fail, especially if exposed to extreme conditions (e.g., water, dust, or voltage spikes). While SRAM s systems are robust, there s still a risk of malfunctions that wouldn t occur with a mechanical setup.

**5. Weight Considerations**

While the E1 groupset is lighter than traditional cable-based systems, it is still heavier than a high-end mechanical groupset (e.g., SRAM Force or Shimano Ultegra). For climbers or riders who prioritize weight savings, this may be a minor drawback.

**6. Learning Curve**

Riders new to electronic shifting may need time to adjust to the feel and operation of the E1 system. Features like customizable shift maps and wireless connectivity can be overwhelming for beginners.

**7. Compatibility with Non-SRAM Components**

The E1 groupset is optimized for SRAM components. Mixing it with non-SRAM parts (e.g., Shimano wheels, Campagnolo brakes) may not yield the best performance or compatibility, though it can often be made to work.

**8. Potential for Overkill**

For riders who primarily ride on smooth roads or don t need advanced features like wireless connectivity, the E1 groupset may offer more than is necessary. A mechanical groupset could suffice for simpler applications.

---

### **Conclusion**

The SRAM 2024 **48/35T 125mm E1 Groupset** is a cutting-edge, wireless electronic drivetrain that excels in performance, responsiveness, and integration with modern cycling tech. It is ideal for riders who prioritize smooth shifting, customization, and a lightweight, cable-free experience. The system s durability, weather resistance, and compatibility with SRAM s ecosystem make it a strong choice for serious cyclists, gravel riders, and those who enjoy advanced features like smartphone connectivity.

However, the high cost, battery dependency, and potential for electronic failure are significant drawbacks. It may not be the best fit for casual riders, budget-conscious cyclists, or those who prefer the simplicity of mechanical systems. Additionally, the need for specialized maintenance and the risk of part availability issues could be concerns for some users.

---

### **Recommendation**

- You prioritize wireless shifting and advanced features like customizable shift maps or smartphone integration.

- You re uncomfortable with the idea of managing a battery or potential electronic failures.

- You primarily ride on smooth roads and don t require the extra weight savings or customization.

- If you like the E1 system but want to save money, consider a **used or refurbished** E1 groupset, as SRAM s electronic systems tend to hold their value well.

- For a more budget-friendly electronic option, look at **Shimano s Di2** groupsets, which offer similar features at a slightly lower price point.

- If you prefer mechanical shifting, SRAM s **Force eTap** (if available) or **Shimano s Ultegra Di2** are excellent alternatives.

Ultimately, the E1 groupset is a fantastic choice for riders who want the best in electronic shifting technology, but it s not for everyone. Weigh your priorities carefully before making a decision.
