Bicycle triathlon aerobars, also known as tri-bars or aero bars, are handlebar extensions commonly used in triathlon and time trial events. These aerodynamic attachments are designed to optimize the rider's position on the bike, reduce wind resistance, and enhance overall speed and efficiency. They serve several important functions:
Improved aerodynamics :
The primary function of triathlon aerobars is to reduce wind resistance or drag. By extending the rider's arms forward and allowing the body to adopt a more streamlined position, aerobars minimize the frontal area that faces the wind, which can significantly improve the bike's aerodynamic efficiency. This reduction in drag can result in faster speeds and improved energy conservation, especially in flat or rolling terrain.
Relaxed and efficient riding position :
Aerobars enable the rider to achieve a more aerodynamic posture by resting their forearms on the padded extensions. This position lowers the rider's upper body and reduces the strain on the lower back, allowing for a more comfortable and efficient riding experience, particularly during longer-distance events like triathlons.
Enhanced power transfer :
The forward position created by aerobars can help optimize power transfer from the rider to the pedals. By engaging larger muscle groups and reducing the reliance on smaller supporting muscles, the rider can generate more power and maintain a consistent cadence, resulting in improved speed and efficiency.
Multiple hand positions :
Most aerobars feature multiple hand positions, allowing the rider to switch between resting on the forearms, gripping the ends of the extensions, or utilizing the base bar of the handlebars. These different hand positions help alleviate fatigue, provide options for comfort during long rides, and allow for slight adjustments in body position to adapt to varying terrain or conditions.
Integration of gear and hydration systems :
Many triathlon aerobars are designed with additional features to enhance functionality during races. These can include mounting options for water bottle cages, nutrition storage, electronic devices such as bike computers or GPS units, and even integrated shifters for gear changes.
It's important to note that using triathlon aerobars requires practice and familiarity. The change in riding position and handling characteristics may affect bike control, especially during turns, climbs, or descents. Cyclists should ensure they have sufficient experience and confidence before incorporating aerobars into their rides. Additionally, bike fit adjustments may be necessary to optimize comfort, power output, and aerodynamic efficiency when using aerobars.
