I’m also having a problem with inaccurate calibration of my SNAP 17. I only use the Wahoo App for spindown.
I thought the issue is caused by a longer spindown time due to a different trainer tire. Wahoo tells me that this isn’t a problem. I would love to see some numbers to back that up. I’m hoping that someone with a SNAP and a power meter on their bike will run an experiment and post the results.
I am having the same issue. Kickr will not calibrate. I have Had zwift for over a year now and really enjoyed it but now this issue is not something i want to deal with especially when I am paying membership fees.
Paul, Jim, reading other posts I think there was a Bluetooth issue with the latest Zwift update that caused some trainers to lag changes in resistance, and not be able to complete a spin down. For me, my trainer stuck at 2 mph even though the flywheel had stopped spinning.
Resistance control worked fine once I switched from Bluetooth to Ant+. However, there was no longer a button to perform a spin down so I need to look into that more.
Thanks, Robert. Now that you point it out,my problem began after the Zwift update. My trainer gets stuck at 2 mph after the flywheel stops spinning. I submitted a request to support.zwift.com and will post the answer when I get a response.
I messaged support.zwift.com and received a response immediately. They sent out an update, which I downloaded on my Mac. I will try it tonight, but great support from Zwift!
I am having the same problem with Zwift and spin down failing on Kickr Snap.
Did this for years with no problems.
Stuck at 2 mph or similar like others reporting
Wahoo bolt spin down works without issue- annoying to have to stop my ride and then log out of zwift spin down then relog back into zwift.
Mention of a mac update- any news of an iOS one? I am using that. Agree update may have caused.
Don’t think this will help everyone here, but I have a kickr core and was having this issue today. Specifically having to put out huge watts to get speed up to 23mph then taking forever to come down with failed calibration as the result.
I realized I was trying to calibrate on a 3% gradient with trainer difficulty set to max. By turning trainer difficulty all the way down i removed the simulated resistance of the gradient and was easily able to spin up to 23mph with a successful calibration. Also think starting from a complete stop may be important.
Mine finally worked after I disconnected ANT and reverted to Bluetooth. Switched off Bluetooth on my phone. Did a Zwift update as well. The resistance in a ride wasn’t working either now I think it is. Wahoo kick snap
Hi I’ve updated Wahoo app and Zwift app. Disconnected all devices, and I can’t get Kickr 2018 over 26 kph in either program. It just stopped working 2 weeks ago and I’m not having any success. I’m using Bluetooth on apple IPhone and IPad and nothing works
Hi all. I have a 2017 Wahoo Kickr that was purchased in late 2018 brand new. For the last 2 years I have NEVER had an issue with connecting my trainer to zwift. However, this winter season, like others, have noticed that I cannot perform a spin down in Zwift. Even with a spin down with the Wahoo app, the resistance does not change appropriately when riding on the hills nor do workouts in Zwift work. I’ve messed with calibration as well as ERG mode. Anyone have any insight on this? Do I contact Zwift or Wahoo?
