Calibration issues tacx + MTB

A friend has an MTB and a tacx wheel on trainer. She has been unable to calibrate the trainer at all - even in the hardest gear she can’t get it to the required speed. Garmin after all sorts of trouble shooting have suggested that she get a trainer tyre. Is this likely to solve her issues or are they just fobbing her off?


From what she tells me it sounds like she is spinning out without ever getting up to speed. I’m trying to help her troubleshoot from across the country so it’s hard to know for sure what the issue is.

It’s a little more work, but having her shoot a video of the calibration, including the device in view might be worthwhile.

All great questions! I don’t know the answers. I have sent her the link to this thread so she can decide what she’d like to do next.
