I’m interested in hearing about issues that people are having with the Kickr Snap trainer while running TrainerRoad.
I’ve been running this trainer for almost a year now. It has a few quirks that are not happening on the Kickr’18 trainer. Some of which are problematic. First, the power reporting and resistance seems to be off. Even when the trainer is in ERG mode, it seems to vary the power and resistance depending on the wheel speed. Initially I was trying to use the small chain ring to save the wear on the big ring, but I soon noticed that the resistance was way harder in the small ring, i.e. at lower wheel speed, than it is in the big ring, at higher speed. I’ve done several experiments to make sure this is not just a perceived effort issue. My cadence is consistent in either case. But the intensity of the effort is way more at low wheel speed. I don’t know why this is happening, but I’ve ended up having to use my highest couple of gears on the trainer in order for the workouts to be doable, when I understood that ERG mode was supposed to be consistent power/resistance regardless of gearing or wheel speed. I’ve confirmed this issue with a power meter and Garmin, so I’m pretty sure its not just perceived.
Additionally, and probably related to the first issue, is that my trainer typically gets quite warm. When I’ve tried to use lower gears/wheel speed, it actually gets very hot. I’m talking about the flywheel. Its nearly too hot to touch after a hard ride. But when I am in higher gears it just stays warm. Recently, it got very hot, and the trainer quit reporting power at all, and TrainerRoad app kept stopping the ride and said “no power meter detected” or something. I had to keep forgetting the device from the app and then re-adding it to get it to show power again, until it would drop again. I don’t know if this is related to or caused by the heat or what, but it was very frustrating.
I’ve updated firmware, I’ve done calibrations and everything Wahoo and TrainerRoad suggest. I’ve tried using the trainer in other modes. I’ve played with all the settings etc. I’ve tried to read online and talk to Wahoo about it, but it doesn’t seem like others have had this issue. But this is an issue because I don’t know what my FTP really is, or if the trainer is really giving me useful power data since it seems variable depending on the wheel speed.
Has anyone else been experiencing this or something similar, and if so have you found a solution? I understand how the flywheel and resistance work on the trainer so as to cause the heat, but should it really be getting very hot? How hot is too hot, and could that cause the bluetooth or power reporting to quit working? I’ve used the Kickr’18 and it didn’t have this issue, and have friends with that trainer that said they’ve never had that problem. Do I have a defective unit? If anyone knows more about this than me, I’d appreciate your suggestions, thanks.
If there are other Kickr Snap issues people are having, I’d like to hear about those too.
