Some background: I’m currently using an old bike (with Campag) on a Tacx Vortex for TR. Even with calibrating before (well, after the warm-up) each ride it feels the power/resistance can vary quite a lot from ride to ride, e.g. similar sweet-spot workouts sometimes feel very easy and sometimes impossible in a way that I don’t think is down to other things (like freshness, nutrition etc). And this is very frustrating. So, I’m considering two options. Either (a) a one-sided pedal PM and using powermatch for TR workouts or (b) get a mid-range direct-drive trainer. Obviously this wouldn’t give me power outdoors but would likely be a better TR experience.
I’m asking then for thoughts on powermatch and whether it makes for a decent TR experienced matched with something like a Tacx Vortex. Or if you had the choice would you go for a direct-drive trainer. Any views on this or better ideas welcome!
