Triathlon aerobars have become the most crucial element for any triathlete looking to improve their aerodynamic performance. If you're thinking about taking the next step in your competitions or simply want to optimize your position on the bike, this guide will provide you with all the necessary knowledge to choose the best triathlon aerobars and triathlon clip-ons on the market.
In this comprehensive guide of over 30,000 words, you'll discover everything from basic concepts to the most advanced installation and configuration techniques. We'll guide you step by step so you can make informed decisions and completely transform your triathlon experience.
Triathlon aerobars, also known as triathlon clip-ons or aero bars triathlon, are extensions that mount on your bike's handlebars to allow you to adopt a more aerodynamic position. These revolutionary components aren't just accessories; they're the difference between competing and dominating in the cycling segment of any triathlon.
When you pedal in a traditional position, your body acts like an invisible brake against the wind. Wind tunnel studies demonstrate that approximately 80% of the resistance you face while cycling comes from aerodynamic drag, not from ground friction or the bike's mechanical resistance.
Triathlon aerobars allow you to significantly reduce your frontal area, which is the surface of your body that faces the wind. By adopting a lower and more compact position, you can reduce aerodynamic drag by 20% to 30%, translating to energy savings of 15 to 40 watts depending on your speed and wind conditions.
In triathlon, especially in long distances like Ironman, every saved watt accumulates exponentially. A 20-watt saving maintained for 4 hours can represent a time improvement of 8 to 12 minutes, enough to completely change your ranking in a competition.
The best triathlon aerobars on the market, like the Masamune models from Tetsuo, have been tested in wind tunnels and can offer immediate savings of 15 to 20 watts simply by changing your front cockpit.
Triathlon clip-ons were born in the 1980s when triathletes began experimenting with more aerodynamic positions. The first models were simple welded aluminum bars that attached to the handlebars with basic clamps. Although rudimentary, these early attempts demonstrated the potential of aerodynamics applied to cycling.
The arrival of carbon fiber in the 1990s marked a turning point in the development of triathlon aerobars. This revolutionary material allowed for creating more complex, lighter, and aerodynamically efficient designs. Pioneer brands began investing in research and development, using wind tunnels and computational fluid dynamics (CFD) analysis to optimize every curve and angle.
Today, aero bars triathlon represent the culmination of decades of research and development. Brands like Tetsuo, with their experience in carbon fiber manufacturing for Formula 1, have taken technology to previously unthinkable levels. Their products are designed with millimetric precision and tested by elite athletes under the most demanding conditions.

Pads are fundamental for comfort during long sessions. The best triathlon aerobars incorporate high-density foams with antimicrobial and non-slip treatments.
Tetsuo uses ARAI EVA foams with anti-moisture and anti-absorption properties, capable of maintaining their shape up to 60°C without deforming.
The mounting system determines compatibility with your bike and installation ease. Modern systems use:
Dual Stack: Compatible with most modern handlebars with two anchor points Central Stack: For handlebars with a single central anchor point
The best triathlon clip-ons incorporate systems that allow adjusting the armrest angle. Tetsuo's K Wedges allow increasing the angle from 10° to 20° in 5° increments, offering maximum customization.
Aerodynamics is the main reason why triathlon aerobars have become indispensable. Benefits include:
Frontal area reduction: By bringing your arms together and lowering your torso, you significantly reduce the surface facing the wind.
Airflow optimization: Well-designed aero bars triathlon channel air around the body more efficiently.
Turbulence elimination: A more aerodynamic position generates less turbulence behind the cyclist.
In addition to aerodynamics, triathlon clip-ons offer significant biomechanical advantages:
Muscle load redistribution: The aerodynamic position uses different muscle groups, which can reduce fatigue in specific muscles.
Power improvement: Many cyclists find they can generate more power in an aerodynamic position due to core muscle activation.
Running preparation: The forward-leaning position helps "open" the hips, facilitating the transition to the running segment.
Don't underestimate the psychological impact of using quality triathlon aerobars:
Confidence: Knowing you have optimal equipment gives you mental confidence Concentration: The aerodynamic position can help maintain focus during long distances Motivation: Visible time improvements motivate more intense training
