WHEELTOP EDS TX Wireless Electronic Groupset 2x3-14 Speed Road Bike Rim Brake

Recommended pairing

WHEELTOP × CHOHO Hollow Flat-Top Chain

Pairs perfectly with WHEELTOP EDS — officially recommended. Fully hollow, flat-top plates keep the drivetrain smooth and quiet while cutting weight.

11-speed for Shimano 11s cassettes  ·  12-speed for Shimano and SRAM AXS 12s

The Complete Shift Kit

Open the WHEELTOP app and tap + Start Using. It searches for nearby EDS TX components over Bluetooth, showing a Searching for devices screen. Once your derailleur turns up, select it and name it yourself, then tap Finish — the app connects automatically, showing an Accessing data… prompt while it pairs — just keep the derailleur powered on and within range. When it's done, the screen switches to Connected, and the home screen lists all four components — rear derailleur, front derailleur, and both shift levers — each showing its live battery reading, with the rear and front derailleur cards also listing firmware version and MAC address.

Tap the settings icon in the bottom corner, then open Flywheel Settings and select your cassette's brand and speed so the derailleur knows exactly how many gears to index across.

Shift the rear derailleur onto the smallest cog and the front derailleur onto the largest chainring, then start calibration in the app.

If you notice any chain rub when shifting between chainrings, dial in each gear individually on the Fine-Tuning screen.

Customize Your Shift Buttons

Assign what each button on the left and right shift levers does — no two riders shift the same way.

Ride Data and Turn-by-Turn Navigation

Switch to the ride screen for distance tracking and a full history of past rides — each entry logged with duration, average speed, and calories burned.

One-Tap Firmware Updates

When a new firmware version is available, the app flags it right on the home screen for the affected component.

Switch between Standard and Racing mode directly in the app. Each mode is tuned for a different riding style — no tools, no hassle.

Inspected and Tested Before Dispatch

Every groupset is brand new, and each one is inspected, paired and tested before it leaves us. That's why it reaches you new, fully working and free of marks, ready to fit.

Photographed, Filmed and Weighed

Each order is photographed and filmed when packed, and the parcel weight is recorded at dispatch.

Gift Box and Wooden Box

Ships in a printed "HELLO!" gift box with a zip tear strip. Inside, every electronic part is bubble-wrapped, sealed in a white frosted bag and packed in a wooden box: a free upgrade for 360° protection against crush damage in transit.

Returns Checked on Arrival

Every return is photographed and filmed when it's opened, and compared with our dispatch photos and video. It must be the item we sent, complete. Please return it in the original wooden box. Missing or different items are handled under eBay's returns policy.

Is the Hanger Straight?

A bent hanger tilts the rear derailleur, which causes poor shifting, chain noise and difficult calibration, no matter how carefully it is set up.

How to check: look from behind the bike. The hanger should hang straight down, parallel to the cassette cogs. If it is bent, straighten it with a hanger alignment tool or fit a new hanger.

Does the Hanger Have a Step?

Compatible

Clear step at the bottom

Not compatible

Very small step

The small tab next to the mounting bolt must rest on the step at the bottom of the hanger, so the derailleur can swing forward and back.

Small step? Fit a hanger with a larger step, or a derailleur hanger extender. Otherwise the derailleur stays rigid and cannot be set up.
