Zwift cog chain problem

Hello, i just installed the zwift cog but when i stop pedalling the chain loses tension because it’s trying to keep rolling. What did i do wrong?

Hi @Nick_Huyghe,

Welcome to Forums. This is Haziel from the Zwift Support team, and I truly appreciate you reaching out with your concern. I’m here to help you.

I understand how important it is for you to have everything set up properly for your Zwift Ride. After reviewing your account, it seems that you are referring to the Zwift Ride, I want to ensure you have the correct thru axle adapters installed on your trainer.

It might also be helpful to take a look at this article Setting Up Your Zwift Ride Smart Frame. Please check if your frame is installed “square” on the trainer. If it’s leaning to one side or not perpendicular to the rear axle, it could cause the chain not to run parallel to the rear cog, leading to it dropping off the tension pulley.

We’re here to support you, so if you have any further questions or need additional assistance, please don’t hesitate to contact us.
