After logging 20 hrs Zwift riding time on a Tacx Vortex Smart, I’m wondering what benefits there would be in upgrading to the Wahoo Kickr.
My principal reason for asking is that I struggle to generate a high w/kg on the hills with the Vortex - I either end up using a big gear at a very low RPM or a lower gear at, say, 40RPM, neither of which is sufficient to generate a w/kg typically higher than 4-5. I therefore get dropped in group rides or when trying to follow other riders, and also riding at such low RPMs is unrealistic and uncomfortable.
Has anyone made this jump? And if so, does the Kickr provide a quantifiably better “experience” than the Vortex, particularly going up-hill?
