Wheeltop EDS GeX Wireless Electronic Gravel Groupset (1 X 7-14 Speed)

Why Riders Choose the GeX

Fully Wireless — No Cables, No Compromise Bluetooth and ANT connectivity ensure a stable wireless connection between the controller and derailleurs, offering a responsive, smooth, and precise gear shift. The wireless design makes installation easier and offers an untethered ride. No shift cables to route, no housing to cut, no ferrules to chase down. The bars are clean, the build is clean, and the bike looks the way a modern gravel build should.

3–14 Speed Compatibility — Your Cassette, Your Choice The most noteworthy feature is compatibility with 3 to 14 speeds. Traditionally, changing the number of speeds required replacing the entire electronic groupset — with EDS GeX, you simply change the cassette, crankset, and chain to adjust the speed configuration. The system is compatible with Shimano HG freehubs and cassettes, as well as SRAM chains and chainrings, providing mix-and-match flexibility that premium brands increasingly restrict.

Medium Cage (75mm) — Up to 48T Maximum Cog The medium 75mm cage supports a maximum sprocket size of 48T, covering the full range of standard gravel cassette configurations. Ideal for gravel and adventure riding where a wide-range cassette is needed but full MTB gearing isn't required. If you need 52T maximum cog capacity for loaded touring or technical climbing, the long cage (93mm) variant is also available.

RA7800 Hydraulic Disc Brakes — CNC Ceramic Piston Calipers The RA7800 caliper features a CNC unibody design with 21mm dual ceramic pistons and a unidirectional oil circuit — delivering consistent, modulated stopping power in the wet conditions that define Pacific Northwest riding for nine months of the year. Ceramic pistons reduce friction and run cooler on long descents, extending pad and piston life over standard aluminium alternatives.

20,000 Shifts Per Charge — Effectively Maintenance-Free The battery delivers up to 20,000 shifts per charge and withstands up to 800 recharge cycles. In real-world use that translates to months between charges for most riders. One user's assessment says it better than any spec sheet: "I've been running this on my Dolan gravel bike since last October. I have totally abused it, I have not cleaned it, I have not charged it, and it has not missed a beat."

IP67 Waterproof The IP67 rating enables confident cycling in rainy weather, crossing streams, and cleaning the device, with water immersion resistance of up to 1 metre for 30 minutes. Not splash-resistant — genuinely waterproof. Built for the conditions you will actually ride in.

App-Controlled Setup and Customization The Wheeltop app allows you to pair components, monitor battery life, customize shift sensitivity, and remap gear sequences — putting setup control directly in your hands rather than requiring a dealer visit. Programmable gear mapping gives gravel cyclists and fast-packers granular control over how the system behaves across their chosen cassette range.

Multi-Shift Function Hold the shift lever and the derailleur sweeps multiple gears in a single action — dramatically faster than single-click shifting for large gear changes on steep terrain. "The way it shifts the entire cassette in one go when you hold the lever is spectacular."

BikeRadar Tested BikeRadar positions the EDS GeX as a direct competitor to SRAM's Apex XPLR AXS and Shimano's GRX Di2 — the two benchmark wireless gravel groupsets — at a price point that makes both of them look significantly overpriced for what they deliver.

What's Included

• EDS GeX rear derailleur (75mm cage)
• Drop bar shifter/brake lever set (left and right)
• RA7800 hydraulic disc brake calipers (front and rear)
• Magnetic USB-C charging cable
• Wheeltop app pairing instructions

What's Not Included

Cassette, chain, chainring, crankset, and bottom bracket are sold separately. The GeX is compatible with standard Shimano HG cassette bodies and works with Shimano and SRAM chains and chainrings — allowing you to build on components you already own or choose freely from the market.
