Wireless Electronic Gravel Groupset — Rim Brake

WHEELTOP EDS GeX

Rim Brake — Carbon Fibre Lever

A fully wireless electronic groupset engineered specifically for gravel and mixed-terrain riding. Rechargeable derailleur battery, IP67 weather sealing, 3-14 speed compatibility — purpose-built for adventure beyond the pavement. Ships with an integrated rim brake shift lever that pairs with your existing rim brake calipers — no hydraulic lines, no caliper changes required. Rim brake frames only.

What's Inside the Kit

Rear Derailleur & Rim Brake Shift Lever — Built for Gravel

Wheeltop EDS GeX rear derailleur

EDS GeX Electronic Rear Derailleur

Powered by a 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 Rim Brake Shift Lever

The GeX shift lever unifies electronic gear control with a mechanical rim brake in one ergonomic lever body. Shift up or down with a button press — the derailleur responds with zero cable lag. The lever pairs with your existing rim brake calipers via standard caliper cable pull — no hydraulic lines, no caliper changes required. Carbon fibre lever body for a light, rigid feel.

Cockpit

Carbon Fibre Lever — Light, Stiff, Precise

Every GeX Rim Brake build ships with the same carbon fibre lever body — a closer look at the material and the cockpit ergonomics.

Carbon Fibre Body — Light, Stiff, Precise.

The lever body is high-grade cold-laminated carbon fibre — light and rigid, built to pair with your existing rim brake cable. The woven surface texture holds grip through wet descents without repositioning. The shift button sits exactly at thumb reach: index finger pulls the rim brake lever, thumb taps the shift button — no hand movement required.

One Lever, Two Functions.

Brake and shift from the same contact point. The lever body handles the cable-pull rim brake, the button handles the gear command — both without taking your fingers off the bar.

Before You Order

Compatibility & Buyer Notes

Please review the following before purchasing to ensure correct fitment.

1x Drivetrain Only

Designed for single-chainring setups only. Not compatible with double or triple chainring systems.

Choose the Right Cage Length

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.

This Listing is for Rim Brake Only

The levers included are rim brake levers — compatible with standard caliper brake cable pull. If you ride a disc-brake frame, please see our separate disc brake listing. Rim and disc brake levers are not interchangeable.

App-Based Setup Required

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

FAQ
What cassette speeds is the WHEELTOP EDS GeX compatible with?

The WHEELTOP EDS GeX 7-12 Speed Groupset is compatible with 11-speed and 12-speed cassettes. For exact compatibility with your specific drivetrain setup, check the detailed product specifications on our Aoeagle product page to ensure optimal performance with your current wheelset.

How difficult is it to install the WHEELTOP EDS GeX derailleur?

Installation requires basic mechanical knowledge and typically takes 1-2 hours for most riders; you'll need standard hex keys, a screwdriver, and ideally a bike stand. We recommend consulting the official WHEELTOP installation manual or watching certified installation videos, and if you're unsure, a local bike shop can handle the setup for you.

How long does the battery last on the WHEELTOP EDS GeX, and how do I charge it?

The OX2.0 battery provides approximately 24,000 shifts per charge (~60+ hours of typical riding), and charges fully in about 2 hours using the proprietary magnetic charging cable. The battery is user-replaceable—simply remove 4 screws with a 2mm hex key to swap in a fresh OX2.0 pack when needed.

Does the WHEELTOP EDS GeX work with my Garmin or Wahoo cycling computer?

Yes, the WHEELTOP EDS GeX supports both ANT+ and Bluetooth protocols, allowing seamless connectivity with Garmin, Wahoo, and other compatible devices plus the official WHEELTOP app. Download the app to your smartphone, pair via Bluetooth, and you can monitor battery status and perform firmware updates directly.

How does the WHEELTOP EDS GeX compare in price to Shimano Di2 or SRAM AXS?

At approximately $399, the WHEELTOP EDS GeX offers significant cost savings compared to comparable Shimano Di2 or SRAM AXS systems while delivering IP67 waterproofing, dual-protocol connectivity (ANT+ and Bluetooth), and a user-replaceable battery—making it an excellent value for riders seeking electronic shifting without premium pricing.

Is the WHEELTOP EDS GeX waterproof and suitable for all-weather riding?

Absolutely—the WHEELTOP EDS GeX is rated IP67 waterproof, meaning it's fully protected against dust and submersion up to 1 meter, making it ideal for rain, mud, and wet conditions. The derailleur is engineered for durability and reliable performance in harsh environments without requiring special maintenance.
