WHEELTOP EDS TT Triathlon and Time Trial Setup Guide

How the WHEELTOP EDS TT wireless groupset fits a triathlon or TT bike: what you need to check, installing the bar-end shifters and derailleurs, and app setup.

Quick answer: the WHEELTOP EDS TT is a 2x wireless groupset made for triathlon and time trial bikes. It includes a pair of SW-TT7110 bar-end shifters for aerobars with a 19.5mm (±0.5mm) inner diameter, an electronic rear derailleur (7–14 speed, largest sprocket 30–36T) and an electronic front derailleur (chainrings up to 53T). It is a rim brake kit: you keep your own brake levers and calipers.

Why Wireless Suits a TT Bike

You shift from the aerobar tips without leaving the aero position, and with wireless shifting there are no shift cables to route through the extensions and frame.

Installation Steps

  1. Fit the bar-end shifters into the aerobar extensions and set the button angle so you can reach it in the aero position.

2. Mount the rear derailleur on the hanger and check the hanger is straight.

3. Mount the front derailleur and line it up with the outer chainring.

4. Fit and size the chain for your chainrings and cassette.

5. Charge both derailleurs with the magnetic charging cable.

6. Pair everything in the WHEELTOP app, set the cassette speed and calibrate. Follow the WHEELTOP app setup guide.

7. Set the button functions, then shift through every gear on a stand before riding.

Race-Day Tips

  • Charge both derailleurs before a race.
  • Use Racing mode for the quickest response; Standard mode sleeps when idle to save battery.
  • Check the shifter coin cells (CR2032) before a big event.
