Sticky draft simple example-
You are drafting behind another rider of the same weight, height, bike, etc. and he is putting out 4 w/kg on a flat road. You can be be sitting on his wheel at 3.7 or 3.2 w/kg. The stickiness prevents you from jumping out of the draft at 3.7 like you would in the real world (or you would run into the back of him). drafting in a big pack has a similar concept, but lots more variables. Efficient Zwift riders know how to surf the pack on minimum watts.
You can also see the stickiness when you are passing a group of slower riders and you must give a little push to avoid getting stuck to their group.
And you can also tell if you are getting draft benefit if your guy sits up and rides the tops of the bars. When you start going off to the side of somebody, you'll see your guy drop back down because he's fighting the wind again. And you can see that he sits up well before the "Close the Gap" stuff starts showing up.
So......clarifying a few Zwift items.
When your Avitar sits up iin a group itâ€™s actually meaningful - drafting in progress.
What makes your Avitar stand out of the saddle? Mine almost never stands and when it does, itâ€™s for like a second.
Can someone explain the â€śdifficultyâ€ť setting a bit? I have mine set at about 55/60%. I had it at 100%?a while back and it killed my knees (although I have no knee problems out on the road).
Yes, sitting up means drafting. One thing I learned on this forum is you can even be drafting when it looks like you're off to the side -- what you see on your screen isn't necessarily what others see. So sitting up is best indicator.
Avatar stands when climbing at cadence below 70. Also when sprinting real hard like 10 watts/kg.
100% resistance is supposed to equal what the resistance would be for a given grade in real life.
