I’m having some issue with my new Zumo, I’m tempted to try swap it at Halfords as I think it must be faulty.
The power fluctuates quite a lot, even at a steady cadence, I also use ERG mode quite a lot, and with the power fluctuating so much ERG seems to be trying to over correct itself constantly and adding to the issue. I also find ERG mode to be very fast to react, faster than the trainer can react to power increase. So as soon as a sprint comes up, even a tame 500W sprint, then the turbo just increases intensity super high until it’s impossible to pedal.
I’ve updated the firmware, calibrated it while warmed up. I am using Zwift, I’ve tried ANT+ and BT but always the same.
This is my first direct drive turbo, but my previous smart wheel on turbo had none of these issues, maybe I should have stuck with that!
