I have tried to read through this thread and I’m not sure if what I’m experiencing with my Core is acceptable/normal or not.
Basically when keeping a smooth pedal stroke and no increase in torque/power it seems fine. But when trying to increase power I feel what I would describe as a vibration? Sort of like crunchy bearings. It doesn’t really make a sound exactly which makes it hard to make a video. I feel it more through the frame. And the power increase can be as small as a 20-30 watt increase.
Its also most pronounced on the down stroke which is when the most torque would be applied which makes me think its either just the system applying more resistance or there is something just a tiny bit loose somewhere that moves with the extra applied torque.
In november I installed a new bb, cassette, chain, and crankset so drivetrain wear shouldn’t be the cause. Recleaned and waxed the drivetrain just to be sure thats not the issue.
So I’m not sure if this is just how additional resistance feels on a Kickr Core or if its a problem. Its been like this since I got it so hard to know what is normal. Does this sound familiar to anybody?
On a side note, does anyone experience abnormally high resistance when not in a workout? For example when warming up the trainer (in the app but no workout loaded) it usually takes 120watts to ride 21km/h (13mph). This is the same in both the trainerroad app and the wahoo app. I have done spin downs in both apps and this seems to be the baseline for both when not in a workout.
Once i start a trainerroad workout the resistance lets go and resumes what feels “realistic” for riding on a flat road. (i don’t have a pm). I have also had post workout where I want to keep spinning but the brake jams on to the point of not being able to pedal. I stop pedaling and the brakes lets off. Then begin pedaling and the brake goes on full. This has only happened a couple times so not sure what is going on.
