I am using a dumb (Ascent Fluid non-adjustable) trainer and a cadence/speed sensor and I just completed my ramp test way above my estimates (265w vs. 190w). I’ve been riding 5-6 days a week but only for only a couple of months now and strava has my estimated watts between 150w and 200w for most rides, so 265w seems unrealistic (but I guess I don’t have much to judge it by).
What do I need to look out for to get an accurate measurement on a dumb trainer with no powermeter? I didn’t notice any slipping but I can’t help but wonder if I should have raised the roller more. If raising the rollers drastically changes the result, how much do I raise it?
I’ve read that with dumb trainers with rollers, the estimated power is way off because of the heat generated by the trainer, is this true? I touched the wheel after the test and it wasn’t much hotter than ‘warm’.
Lastly, does it matter if my FTP is too high, so long as it’s constant? I imagine that I could setup my trainer the same each time then the high demands of my workouts will be met by the over-weighted FTP.
