Smart Control Full Control from Your Phone
Download the WHEELTOP app to pair, tune, and monitor your drivetrain - all from your handlebars.
1
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.
2
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.
Not Locked to One Speed Count
3
Shift the rear derailleur onto the smallest cog and the front derailleur onto the largest chainring, then start calibration in the app.
Guided On-Screen Alignment
4
If you notice any chain rub when shifting between chainrings, dial in each gear individually on the Fine-Tuning screen.

Step 1 Before Installing Check Your Derailleur Hanger
Please complete these two checks before fitting the WHEELTOP rear derailleur. Only install it once both are confirmed.
CHECK 1
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.
CHECK 2
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.
