WHEELTOP EDS TX Wireless Electronic 2x7-14 Speed Groupset Hydraulic Disc Brake

EDS TX Electronic Rear Derailleur

Driven by a built-in 800mAh rechargeable battery at 7.4V, the EDS TX rear derailleur shifts instantly on a button press — zero cable lag, zero stretch over time. The exact speed count is configured through the WHEELTOP app — supports cassettes up to 36T. The standard pulley wheel uses a 12-tooth positive/negative tooth profile for quieter, more secure chain engagement. Charges through a magnetic Pogopin connector — snap it on, no port covers, no corrosion.

Carbon fiber cage plate with ceramic-bearing oversized pulleys

Oversized pulley wheel systems reduce the chain's wrap angle around each pulley, which means less chain articulation per revolution and measurably lower friction across the full drivetrain.

Same Platform. Hollow Ceramic-Bearing Pulleys.

The TX Oversized Pulley Cage shares the same 800mAh battery, Pogopin charging, BLE/ANT+ wireless, and app configuration as the standard TX rear derailleur. The performance gain comes entirely from the oversized hollow ceramic-bearing pulley wheel system — no learning curve, no setup difference.

Why Oversized? The Chain Wrap Angle Difference.

At 12 teeth, the oversized pulleys are physically larger than a conventional jockey wheel — letting the chain bend through a gentler arc at each engagement. Less arc per revolution means less per-link articulation friction across every pedal stroke. Hollow ceramic-bearing pulleys mounted on a carbon fiber cage keep the drivetrain quieter and more responsive under load.

Precise Front Shifting on Demand

The EDS TX front derailleur runs on its own built-in 500mAh 7.4V rechargeable battery and shares the same magnetic Pogopin charging, and BLE/ANT+ wireless link as the rear unit. Pair both derailleurs to the WHEELTOP app for synchronized setup, gear mapping, and live status — front and rear shift in concert with a single button press from the lever.

Shift with a Button. Brake with the Lever.

A press of the shift button sends the command wirelessly straight to the derailleur — no cable pull, no mechanical play to wear in. Each lever runs on a single CR2032 button battery, swappable in seconds without tools.

Carbon Fiber Body — Light, Stiff, Precise.

The lever bodies on every build are high-grade cold-laminated carbon fiber — light, stiff, and solid under hard braking. The woven surface texture holds grip through wet descents without repositioning. The shift button sits exactly at thumb reach: index finger pulls the 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 brake pull, the button handles the gear command — both without taking your fingers off the bar.

CR2032 — One Battery. Years of Shifts.

Each shift lever runs on a standard CR2032 button cell. Open the battery compartment, drop in a fresh cell, and you're done — no charging cables, no tools, no downtime. A single CR2032 typically lasts well over a year of regular riding.

Available Everywhere

CR2032 cells are sold at any supermarket, gas station, or electronics shop worldwide. If it runs low on a trip, a replacement is never more than a few minutes away.

Rear Derailleur Cage

Same Derailleur. Different Cage.

Both builds use the same EDS TX rear derailleur. The aluminum alloy cage is the rugged, value-focused choice; the carbon fiber cage trims weight from the rear derailleur for riders chasing every gram.

Aluminum Alloy Cage · Rear derailleur 354.2g

Disc Brake Carbon Fiber / Oversized Pulley Cage

Carbon Fiber Cage · Rear derailleur 336.6g (340g with Oversized Pulley Cage)

Build 1

Disc Brake — Aluminum

Aluminum alloy rear derailleur cage and carbon fiber shift levers, with hydraulic disc brake calipers included. A rugged, value-oriented option for disc-mount frames. Standard 12T pulleys.

Build 2

Disc Brake — Carbon Fiber

Carbon fiber rear derailleur cage and carbon fiber shift levers, with hydraulic disc brake calipers included — full ceramic pistons, CNC unibody construction. Best all-round build for disc-mount road and gravel frames.

Build 3

Oversized Pulley Cage — Carbon Fiber Hollow

Replaces the standard 12T pulleys with oversized hollow ceramic-bearing pulley wheels on a carbon fiber cage.

CNC Unibody. Built to Run Cool.

The caliper body is CNC-machined from aluminum alloy as a single unit, ensuring rigidity and long-term safety under hard braking. Shark-fin heat sinks on the caliper body increase surface area for better heat dissipation, slowing down thermal fade on long descents. A unidirectional oil circuit prevents brake fluid from flowing backward, keeping lever feel sharp and response quick.

Full Ceramic Pistons

Full ceramic pistons resist high heat and hold a consistent bite point ride after ride — no fade, no spongy lever after a long climb or fast descent.

Pre-Bled. Ready to Ride.

Hoses are pre-cut and pre-bled from the factory. Unbox, install, ride. The mineral oil system is non-corrosive and easy to maintain at home.

Step 1

Pair Your Components

All Four Components, One Screen

The Connected view puts the rear derailleur, front derailleur, and both shift levers on one screen, so you can check every component's charge level at a glance before a ride.

Step 2

Set Your Cassette Speed

Step 3

Run Initial Calibration

Guided On-Screen Alignment

No guesswork — use the on-screen +R / −L controls to nudge the guide pulley until it sits precisely under the smallest sprocket, then tap Finish.

Step 4

Fine-Tune Every Gear

Need to Go Further?

Open Rear Derailleur Gear Parameters to view or manually edit the exact position value for any gear, then save — a level of precision cable systems simply can't match.

Set It Once, Ride Your Way

Reassign the SW-L and SW-R paddles to trigger whichever shift function feels natural, or tap Factory Restore to reset instantly.

Live Stats While You Ride

Tap GO in the bottom bar to switch into the ride screen, where elapsed time, calories, pace, average heart rate, cumulative shifts, and climb update in real time alongside turn-by-turn map navigation.

Stay Current, Wirelessly

Tap to review what's new, then update over the air — just make sure the component has enough charge before you start.

Pick the Right Build for Your Priorities

Choose Disc Brake (Aluminum), Disc Brake (Carbon), or the Oversized Pulley Cage upgrade based on your weight priorities and drivetrain efficiency goals. All three builds are disc brake only.

Speed Count Fully Configurable in the App

Speed count isn't fixed by the hardware — set anywhere from 7-speed to 14-speed directly in the WHEELTOP app to match your cassette. Verify your current cassette is 36T or smaller before ordering.

Flat Mount Calipers Only

Confirm your frame and fork take 160mm rotors before ordering — the included calipers and hoses must match your frame's specification.

App Pairing Required Before First Ride

After installation, pair both derailleurs to the WHEELTOP app over BLE, set your speed range, and run gear calibration. The app is free on iOS and Android.
