Setup Help

I have an Cateye ISC-11 that seems to be configured correctly on the bike, yet no light is on or flashing when it turns. Its 3mm on either side as instructed. 

Equally my ANT+ USB Dongle isnt being picked up by Zwift - is this a separate issue or linked to the above?


Any help welcomed.

Hi Sean,

Check out our Knowledge Base article here:

It might help you get configured correctly. I’d also try replacing and/or reseating the battery in your Cateye sensor. I’ve sometimes had to move the magnet EVEN CLOSER for my old Wahoo Blue SC speed sensor for it to register.

Hi Eric

Thanks. I’ve changed the battery, the smart trainer is cycleops Fluid 2 which should be compatible. Not sure what else I can do?
