In the real world, it’s about CdA, CRR, and watts. How does Zwift handle this?
To be honest, in the real world the top TT folks ain’t that big. Even the 6’ plus boys. Point being, I feel the algorithm may be skewed a bit towards watts.
I take it in stride, it’s fun, and I choose on my own to ride in my more restrictive aero tuck for racing while using my actual TT bike. We work really hard to get that CdA down in the 0.2XX’s and make power.
Up to about 40 feet per mile, maybe 50 in elevation, I can average 24 to 25mph on my race setup outdoors with only about 240w (3.4w/kg). Zwift it’s more like 23.5 on a pan flat route.
I’m just curious as to how it works it out between raw watts, w/kg, and a CdA estimate based on rider dimensions and equipment choice.
I tend to notice the heavier riders on flat TT’s having the easier time of it, which makes sense, to a point. But 80 to 85kg boys ain’t going to be sporting a 0.220 CdA either. And at those speeds that matters a lot.
