Rattling noise with new Zwift Cog

Hey

Just received a new wahoo kickr core with Zwift cog and when trying to install it for the first time it makes this noise one the cog. It looks like the chain is making the noise when trying to fit in the cog tooth.

Chain seems to be ok but from the above it looks like it’s too loose?

Here is the video with the problem

Hi @Miguel_Moreno2!

Welcome to the forums! Thanks for bringing this query to our attention! Jose here from Zwift.

I’m sorry to hear that your Zwift Cog is making that noise. Thank you for sharing the video and the information with us. How many gears does your bike have? Additionally, could you please check the condition of the rear derailleur and hanger to ensure they are not bent or damaged?

Please let us know how it goes, or feel free to contact us at support@zwift.com. so one of our colleagues can assist you further.

The chain was worn out, I replaced it with a new one and it’s all good now! thanks
