First post, hope people can help.
Am running a Tacx Genius and have done FTP and first proper SS training session. More than happy with feel of trainer, cadence numbers and power measurement - but the speed is off the chart, averaging something like 80km/h.
Looking at the settings in both the Tacx app and on TR the wheel circumference is similar (2096 in TR).
Any ideas welcome.
Obvious one is to run it up in a known gear and cadence in the Tacx app, which I will do at weekend, but after that I am stuck.
