Power and Rollers

(Keith Myers) #1

There is no possible way the watts Swift is calculating for my output on rollers in accurate - it is off by at least a factor of 2.5 - 3.

How do you transfer your power? Are you using power pedals or something like that to submit power to Zwift?

Swift is calculating it based on speed and cadence (and I’m not sure what else). I do not have a power meter.

Ah ok. Makes sense now.
Then Zwift tries to calculate your power. Search for zPower here on the forums or knowledge base articles.
