Wireless Electronic Gravel Groupset

WHEELTOP EDS GeX

A fully wireless electronic groupset engineered specifically for gravel and mixed-terrain riding. 800mAh rechargeable derailleur battery, IP67 weather sealing, 3-14 speed compatibility — purpose-built for adventure beyond the pavement. Ships with integrated hydraulic brake-shifter levers and RA7800 flat mount disc calipers. Disc brake frames (flat mount) only.

What's Inside the Kit

Rear Derailleur & Hydraulic Brake-Shifter — Built for Gravel

Wheeltop EDS GeX rear derailleur

EDS GeX Electronic Rear Derailleur

Powered by an 800mAh built-in rechargeable battery, the GeX delivers approximately 20,000 shifts per charge — months of riding between top-ups for most gravel cyclists. The magnetic snap-on charging connector makes top-ups effortless — no exposed port, no cover to lose. The IP67-rated sealed housing keeps mud, water, and grit out at all times. Available in three cage lengths: 58mm Short Cage (up to 32T), 75mm Medium Cage (up to 42T), or 93mm Long Cage (up to 52T). Operating temperature -20°C to 60°C.

Internal Chain Damper

A precision-engineered damping system suppresses chain slap and prevents dropped chains on rough gravel, washboard roads, and mixed-terrain surfaces — keeping your drivetrain quiet and controlled when the going gets rough.

Integrated Hydraulic Brake-Shifter

The GeX shifter unifies electronic gear control and hydraulic braking in one ergonomic lever body. Shift up or down with a button press — the derailleur responds with zero cable lag. The hydraulic circuit delivers powerful, modulated stopping power running on mineral oil. Lever reach is adjustable up to 8mm. IP65 rated against water jets and dust. Available in aluminum or carbon fiber lever.

Braking System

RA7800 Hydraulic Disc Brake Calipers

CNC-machined unibody calipers with 21mm dual ceramic pistons — consistent, powerful braking in all conditions.

Wheeltop RA7800 hydraulic disc brake caliper

Ceramic Pistons. Unibody CNC Body.

The RA7800 caliper body is machined from a single aluminum block — no seams, no flex under hard braking. Twin 21mm ceramic pistons deliver excellent heat resistance and a consistent bite point across long descents. A unidirectional oil circuit ensures smooth, progressive lever feel from light modulation through to full stop. Compatible with 140mm and 160mm rotors.

Shimano Pad Compatible

Compatible with Shimano L04C, L05A, L04A, and BR-RX810 brake pads — widely available worldwide and easy to source at any bike shop.

Flat Mount. Pre-Bled. Ready to Ride.

Flat mount only — the standard on modern gravel frames. Hoses are pre-cut and pre-bled from the factory: 900mm for the front, 1,550mm for the rear. Unbox, install, ride. The mineral oil system is non-corrosive and easy to maintain at home.

Compatibility & Buyer Notes

Please review the following before purchasing to ensure correct fitment.

1x Drivetrain Only

Verify your cassette max sprocket before selecting: 58mm Short Cage (SS) — up to 32T · 75mm Medium Cage (GS) — up to 42T · 93mm Long Cage (SGS) — up to 52T. Using the wrong cage causes poor shifting or chain derailment.

Flat Mount Frames Only

The RA7800 calipers are flat mount only — not compatible with post-mount frames. Rotor must be 140mm or 160mm.

App-Based Setup Required

Initial calibration must be performed via the WHEELTOP app (free on iOS and Android) after installation.

FAQ
What cassette speeds and chainring sizes does the WHEELTOP EDS-GEX support?

The EDS-GEX supports 3 to 14-speed cassettes with its 75mm medium cage, handling sprockets up to 42T, while the front supports chainrings up to 52T. This makes it compatible with most gravel and road cassettes from brands like Shimano, SRAM, and Microshift.

How difficult is it to install the WHEELTOP EDS-GEX, and what tools do I need?

Installation requires basic mechanical skills and standard bike tools: Allen keys, a chain tool, and a derailleur hanger alignment tool if needed. Most riders can complete the setup in 1-2 hours, though professional installation at a bike shop is recommended for wireless system calibration and optimal performance.

How long does the battery last, and how do I charge the WHEELTOP EDS-GEX?

The WHEELTOP EDS battery delivers approximately **24,000 shifts per charge** (~60+ hours of typical riding). Battery level is monitored in real-time via the WHEELTOP Bluetooth app. Charging uses the proprietary **magnetic charging cable** (not USB-C) — attach it to the magnetic port on the derailleur and a full charge takes about 2 hours. The EDS OX2.0 also features a **user-replaceable battery** (remove 4 screws with a 2mm hex key to swap).

How do I pair and calibrate the WHEELTOP app with my EDS-GEX groupset?

Download the WHEELTOP app, enable Bluetooth on your device, and follow the in-app pairing wizard to connect your groupset in minutes. The app guides you through automatic calibration, displays real-time battery status, and enables OTA firmware updates directly to your derailleur.

How does the WHEELTOP EDS-GEX compare to Shimano Di2 or SRAM AXS in price and features?

At ~$399, the EDS-GEX undercuts both Shimano Di2 and SRAM AXS by $500+, offering 1× gravel-specific design, disc and rim brake compatibility, and ANT+ integration with Garmin and Wahoo computers. You sacrifice some road-racing features but gain better value and gravel-optimized geometry.

Is the WHEELTOP EDS-GEX waterproof enough for wet gravel and muddy conditions?

The EDS-GEX features sealed connectors and weather-resistant electronics designed for off-road durability, handling rain, mud, and water crossings typical of gravel riding. While not submersible, it's engineered to withstand the demands of all-weather gravel cycling with proper care and occasional cleaning.

Where can I buy the WHEELTOP EDS-GEX, and does it come with a warranty?

The WHEELTOP EDS-GEX is available on Aoeagle's eBay store with worldwide shipping and a full manufacturer warranty on all components. Visit Aoeagle's eBay store today to order your EDS-GEX groupset and join the gravel revolution with wireless electronic shifting.
