Being aero on the bike isn’t a trend or a theory, it is real and based on facts.
The more aero you get, while being comfortable and powerful, the faster you’ll go, period.
Tomorrow, the world’s best triathletes will race for glory in Kona. This is the climax of a year of physical, tactical and also technical preparation. All of these racers will ride with a different aero setup, trying to get as much free watts as possible.
As your season is probably nearing its end, this is a great time to start rethinking your aero for next year, to try different things in easy training sessions without risking injuries.
