Electronic vs Mechanical Drivetrains: Which Is Best for Your Ride?

As mountain bike technology continues to evolve, one of the biggest upgrades riders are considering is switching from mechanical to electronic drivetrains. But is it worth it?

At Gravity Nelson, we’ve worked with both systems extensively, and we’re here to break down the pros, cons, and performance benefits so you can decide what’s right for your bike and your style of riding.

⚡ Electronic Drivetrains – Precision, Power & Performance

Electronic drivetrains like the SRAM GX Eagle AXS Transmission offer a number of real-world performance advantages:

✅ 1. Lightning-Fast, Consistent Shifting

Electronic shifting is driven by small motors, not cables, so you get the same precise shift every time—no matter the terrain, conditions, or how hard you're pedalling.

✅ 2. Shift Under Load with Confidence

Climbing a steep switchback and need to change gear? Electronic systems shift cleanly under heavy torque—something mechanical systems often struggle with.

✅ 3. Minimal Maintenance

No more stretched cables or endless barrel tuning. Once an electronic system is set up, it stays dialled and even auto-trims to maintain perfect alignment.

✅ 4. Clean & Customizable

With no cables and fully wireless setups like SRAM AXS, you get a cleaner cockpit and the ability to customize shift functions via an app—left shifter up, right down, or even multi-shift with one click.

✅ 5. Integrated Tech

Modern systems log ride data, track battery life, and allow firmware updates—all from your phone.

🔧 Mechanical Drivetrains – Reliable & Rider-Friendly

Mechanical groupsets like the SRAM Eagle 90 Mechanical Transmission still offer serious value, especially for riders who prefer simplicity.

✅ 1. Affordable & Easy to Replace

Mechanical drivetrains are generally less expensive up front and more budget-friendly when it comes to repairs or replacements.

✅ 2. Trailside Fixes Made Easy

Got a problem mid-ride? A multi-tool and a spare cable can usually get you rolling again—no need to worry about software or charging.

✅ 3. Proven Performance

Modern mechanical systems shift well, especially when kept clean and properly tuned. For many riders, especially those who ride hard in all conditions, this level of control is perfect.
