I apologise if something similar has been posted before.
I ride a wheel on standard tacx trainer and, although I’ve never ridden a smart trainer, I can certainly see the benefit of a smart trainer and erg mode. I do plan to get a smart trainer in the future.
I do wonder though if you lose some benefits by riding in erg mode.
Firstly, when completing intervals with a standard trainer with a power meter there’s often a compromise to be had in terms of cadence to hit a certain power. For example having to spin a few rpm above or below my preferred. This can be a bit frustrating but I wonder if it helps to improve my range of comfortable cadences?
Secondly, to keep at target power requires producing the power but also a degree of concentration and control to keep the power up and now go too much over. It strikes me that this is more similar to riding outside and aiming for a target power.
I’m interested to know what people with smart trainers think.
