Wheeltop EDS-TX: The Game-Changer in Electronic Shifting

For years, Shimano and SRAM have dominated the electronic shifting market, with their Di2 and AXS groupsets setting the gold standard for performance. However, a new contender is shaking things up—Wheeltop EDS-TX. Offering full wireless electronic shifting at a fraction of the price of Ultegra Di2 or Rival AXS, this groupset is challenging the industry heavyweights in a way that can’t be ignored.

But is the EDS-TX just a budget-friendly alternative, or does it truly have what it takes to compete? Let’s dive into the details and see if Wheeltop has delivered a genuine Ultegra Di2 rival—or just a cost-cutting experiment.

What Is the Wheeltop EDS-TX?

Unlike traditional groupsets, the EDS-TX is designed as a drivetrain upgrade kit rather than a full groupset. This means you keep your existing crankset, cassette, and chain while upgrading your derailleurs, shifters, and (in some cases) brake calipers. It’s fully wireless and available in both disc and rim brake versions, making it one of the most versatile options on the market.

What’s in the Box?

• Wireless electronic shifters (hydraulic)
• Front and rear derailleurs
• Brake calipers
  
• Magnetic charging cables
• Small parts and accessories

Key Features: How It Stacks Up Against Shimano & SRAM

1. Wireless Freedom for Any Bike

Unlike Shimano Di2, which still relies on a central battery with wires, the Wheeltop EDS-TX is fully wireless, similar to SRAM’s AXS system. This means cleaner aesthetics, easier installation, and compatibility with older bikes that don’t have internal routing for wires.

2. Unmatched Gear Compatibility

This is where Wheeltop leaves the competition behind. The EDS-TX is the first electronic groupset to support 3-speed to 14-speed configurations—something that neither Shimano nor SRAM offer. With a few adjustments in the Wheeltop app, you can customize the derailleur to work with nearly any cassette.

💡 Imagine upgrading your vintage 8-speed steel road bike to electronic shifting without replacing the entire drivetrain. Wheeltop makes that possible.

3. Weight Advantage

Weight-wise, the EDS-TX weighs only 1,190g, which puts it right in line with SRAM Red eTap and lighter than Shimano 105 Di2.

Performance: How Well Does It Shift?

While specs and pricing are important, shifting performance is what truly defines a groupset.

Rear Shifting

✅ Quick & Reliable – The rear derailleur shifts smoothly and quickly, even under load. It may not be as instantaneous as Ultegra Di2, but the difference is minimal.

❌ No Auxiliary Shifting Buttons – Unlike Shimano and SRAM, Wheeltop does not offer extra remote shifter buttons for climbing or sprinting.

Front Shifting

✅ Reliable & Quiet – The front derailleur includes auto-trim, which prevents chain rub and ensures silent operation.

❌ Slightly Slower Shifts – Compared to Shimano’s front derailleur, the Wheeltop takes a fraction of a second longer to shift, though it never mis-shifts.

Braking Performance

✅ Hydraulic Disc Brakes – Uses mineral oil (like Shimano), making it easy to service.

✅ Shimano-Compatible Brake Pads – Uses standard Shimano L04C, LO5A, and LO4A pads, meaning replacements are easy to find.

Wheeltop App: A Work in Progress

Wheeltop provides an app for battery monitoring, shifting customization, and gear indexing.

✅ Highly Adjustable – Riders can fine-tune each gear, ensuring crisp shifting.

❌ Translation Issues – The app’s English translation is slightly rough, making some settings confusing. Although this is being improved currently.

Final Verdict: Should You Buy It?

The Wheeltop EDS-TX is not just a budget alternative—it’s a legitimate competitor in the world of electronic shifting. While Shimano Di2 and SRAM AXS still have slight refinements, the EDS-TX closes the gap significantly at a fraction of the cost.

For riders looking to upgrade their bike without spending R20,000+, or those wanting electronic shifting on rim brake bikes, the Wheeltop EDS-TX is a game-changer.
