Wireless Electronic Shifter / Derailleur Kit — Rim Brake
WHEELTOP EDS TX — Rim Brake, Carbon Fiber Pulley Cage
A fully wireless electronic shifting kit purpose-built for road bikes and drop-bar bicycles. Front and rear derailleurs shift on a button press — no cables, no housing, no barrel adjusters. Speed count isn't fixed by the hardware — you set it yourself in the WHEELTOP app, fully configurable via BLE/ANT+. Supports cassettes up to 36T. 2X (double chainring, front derailleur included) configuration. The rear derailleur ships with a standard carbon fiber pulley cage, and the shift levers are carbon fiber, pairing with your existing rim brake calipers — no hydraulic lines, no caliper changes required.
Driven by a built-in 800mAh rechargeable battery at 8.4V, 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 carbon fiber pulley cage 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.
7-12 Speed, Set in the App
Unlike mechanical derailleurs locked to a fixed speed count, the EDS TX lets you define your speed range and per-gear position through the WHEELTOP app.
Front Drivetrain — Included
Electronic Front Derailleur — Complete 2× Groupset
Ships with both the front derailleur and rear derailleur — a complete 2× drivetrain groupset, ready to install.
Precise Front Shifting on Demand
The EDS TX front derailleur runs on its own built-in 600mAh rechargeable battery and shares the same 8.4V system, 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.

Rim Brake — Carbon Fiber Lever
The EDS TX Rim Brake build pairs a carbon fiber lever body with your existing rim brake calipers — electronic shifting precision, zero cable clutter, zero changes to your braking setup.
Carbon Fiber Body. Rim Brake Compatible.
The carbon fiber lever body is lightweight, rigid, and built to pair with your existing rim brake cable. Shift electronically on a button press while braking through the lever in the same motion you already know. No new calipers, no hydraulic lines — just cleaner cockpit routing and instant gear response.
Lightest EDS TX Configuration
Without hydraulic calipers, the Rim Brake build is the lightest complete EDS TX kit — front derailleur 191.3g, rear derailleur 336.6g, left lever 202.3g, right lever 214.6g.

Two Riding Modes. One Tap to Switch.
Switch between Standard and Racing mode directly in the app. Each mode is tuned for a different riding style — no tools, no hassle.
Standard Mode
Auto-sleep when idle. Lower power draw, longer battery life. Perfect for long days in the saddle.
Racing Mode
Always-on, maximum responsiveness. Boosted signal power for noise-resistant shifting under pressure.
Pair, Calibrate, Fine-Tune — All in the App
Use the WHEELTOP app to pair your derailleur, run initial position calibration, and micro-adjust each individual gear. No limit screws to guess at — just tap and confirm.
Per-Gear Fine Adjustment
Dial in every sprocket individually. If one gear feels off, adjust it directly in the app without touching the bike — a precision that cable systems simply can't match.

Before You Order
Compatibility & Buyer Notes
Please review the following before purchasing to ensure correct fitment.

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.
Speed Count Fully Configurable in the App
Speed count isn't fixed by the hardware — set anywhere from 7-speed to 12-speed directly in the WHEELTOP app to match your cassette. Verify your current cassette is 36T or smaller before ordering.
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.
