In cycling, “aero is everything.” So pros like Chris Froome get into an aero-tuck (aka “super-tuck”) when descending, reducing air resistance and allowing them to travel faster with less work.
Looking for some rest while descending one of Zwift’s many mountains? You can use the super-tuck. It is literally the easiest way to go faster on Zwift, since it requires you to stop pedaling!
Here’s how it works: if you are on a 3% or steeper downhill moving at least 35mph (57km/h), stop pedaling. Your avatar will enter the super-tuck as soon as your power drops to 10 watts or less.
Once in the super-tuck your rider will travel faster, mimicking the reduced air resistance you would encounter when aero-tucking outdoors.
There is one exception: riders on TT frames cannot super-tuck.
Use in Races
You may have just finished a tough climb or worked hard to grab another rider’s wheel on a descent. Or perhaps you’re just trying to conserve as much energy as possible, so you’ve got legs when you need them! Whatever the situation, the super-tuck is handy when you need to grab a little recovery during the downhill portion of a race.
Most riders reduce their effort on descents to recover. If you can super-tuck in a group of racers who are pedaling at recovery pace, you should be able to maintain the speed needed to hang with the group with little or no work.
But be careful! If the road flattens out or your speed drops below 35mph, you will come out of your aero-tuck and slow down very quickly. This will quickly drop you from the group, and you will have to put in extra effort to catch them again.
