A fully wireless electronic shifting kit built for flat-bar road and dual-chainring gear bikes. Front and rear derailleurs shift on a button press — no cables, no housing, no barrel adjusters. Compatible with 3-14 speed, 10-36T cassettes, fully configurable through the WHEELTOP app via BLE/ANT+. The rear derailleur is available with two cage options — the Alloy Cage (aluminum alloy, standard 12T pulleys) and the Carbon Ceramic OSPW (carbon fiber hollow cage, 12-tooth ceramic bearing oversized pulley wheels) for reduced drivetrain friction. Brake calipers are not included — the TXR is a pure drivetrain kit.
Both versions share the same rear derailleur platform — 800mAh built-in battery at 8.4V, carbon fiber linkage, instant button-press shifting, Pogopin magnetic charging, 3-14 speed / 10-36T cassette range set through the WHEELTOP app. Only the cage material and pulleys differ.

Carbon Ceramic OSPW
Hollow carbon fiber cage upgraded with 12-tooth ceramic bearing oversized pulley wheels (OSPW). The oversized pulleys let the chain bend through a gentler arc at each jockey engagement, reducing per-link articulation losses — the same oversized pulley cage found on the EDS TT triathlon groupset.

Front Drivetrain
Electronic Front Derailleur
Wireless electronic actuation for the front shift — the half of the drivetrain cable systems compromise on most.
Precise Front Shifting on Demand
The EDS TXR 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 synchronised setup, gear mapping, and live status — front and rear shift in concert with a single press of the trigger.

Wireless Electronic Trigger Shifters — Left & Right
Flat-bar trigger shifters that send gear commands wirelessly — no cable routing, no housing, nothing to stretch or corrode.
Shift with a Thumb. No Cables Required.
A press of the trigger sends the shift command wirelessly straight to the derailleur — no cable pull, no mechanical play to wear in. The same trigger shifters used on the EDS OX 2.0 MTB groupset, fitted here for flat-bar road and urban bikes. Each shifter runs on a single CR2032 button cell, swappable in seconds without tools.

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.

Compatibility & Buyer Notes
Please review the following before purchasing to ensure correct fitment.
Flat-Bar Bikes Only — Not Compatible with Drop Bars
The TXR uses flat-bar trigger shifters and does not include drop-bar levers. If you ride a drop-bar road bike, please see the EDS TX instead.
Brake Calipers Are Not Included
The TXR is a drivetrain-only kit. Your existing rim brake or disc brake calipers are retained — only the shifting system is replaced.
Confirm Your Cassette Falls Within Range
The EDS TXR supports 3-14 speed cassettes from 10T to 36T, with the exact speed count set in the WHEELTOP app. Verify your cassette falls within this range 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.
