I don’t have that function on my app for some reason…
But from Strava segment data and riding with others, I put out more power than others at similar speeds.
Im slower than the bike calculator website predicts, I’m slower than my zwift speeds… 180w on zwift gets me 20-21 MPH, I get about 19 on dead flat roads.
I recently did a dead flat Strava segment at 285w, decent 8-10 MPH tailwind and only managed around 24 MPH. About 3 mph slow…
On top of body aerodynamics, wheels and tires can affect this data. Upgrading to CF deep wheels and GP5000’s gave me over 1 mph extra over the crap stock stuff that came with my bike.
