Hi. My wahoo kikr seems to cycle (at consistent rhythm) from expected resistance to high resistance. I’ve done firmware updates and spin downs but the problem seems to persist. Any guidance very much welcome.

Hey @Matthew_Pickering, welcome to the forums. Can you provide a little more information for us. I’m assuming this is in ERG mode and not Level/Slope mode right?

- What version of the Kickr are you using?
- What programs/apps (SYSTM, RGT, Zwift etc) have you found the resistance changing like that and on what platform (windows, Mac, iOS Android, AppleTV) are you using
- Are you using Bluetooth or Ant+?
- Are you making sure that only one program/app is open at one time?
