Hello everyone i got my Whaoo Kickr Core with Zwift Hub today. I have a gravelbike mit a 42 teeth 1x chainring. Therefor my chain is quit long, I noticed that my chain is a bit lose and dose not grip the best, do you guys have a recommendation how long my chain should be or how I can calculate the correct length. Thanks
Hi @Oskar_Wolf welcome to Zwift forum.
Shuji at Zwift HQ here. Can I ask for clarification? You’re putting your outdoor gravel bike on the KICKR Core, correct? Not the Zwift Ride smart frame?
Can you post a photo of what you mean by “chain is a bit loose?” Please show us a wide shot of the entire drivetrain from the right side of the bike.
If the chain was correctly sized for your bike - you should not need to change your chain in order to use the Zwift Cog. It has a 14 tooth cog, and the rear wheel of your gravel bike should also have cogs of similar size on its cassette.
