Training with Aerobars

Lance Watson, Head Coach (National Training Centre, Canada)

One of the things that traditionally sets triathletes apart from ordinary cyclists, and makes them identifiable at a glance, is the set of aerobars usually attached to the front of their bike. Although the use of aerobars has spread beyond the world of triathlon, they are firmly entrenched in triathlon culture and lore.
Popularized by Greg Lemond’s use in the Tour de France, aerobars were actually originally dreamed up by triathletes looking to shave some time off their bike splits. Since their first crude forms in the 80’s, aerobars have transformed into the sleek works of art they are today. However, aerobars aren’t just about looking good, or even being comfortable for that matter (even though these are important considerations) – they are about speed. Using aerobars lets you ride faster while expending the same amount of energy. Aerobars work because they create a more aerodynamic position on the bike – hence their name. Position on the bike is an important aerodynamic factor, as it can cut down on wind resistance by changing the flow of air around the rider and his/her bike.
Aerobars achieve a more aerodynamic position by placing the upper body of the rider in a lower position, with their arms extended out in front of the body. Studies have shown that 20-40 seconds are saved over 40km because of the more aerodynamic position that aerobars create. That is a time saving that most people would love to have without having to train any more to achieve it. However, for this more aerodynamic body position to be effective it must not affect the way the body transfers power to the bike.
Your aerobars should be fit to you and your bike when you purchase the bike, to ensure that they put you in the proper position. If your aerobars are acquired after your original fitting, you need to make certain that they are helping rather than hindering you.
