Handlebar extenders are essential accessories for cyclists who want to improve their aerodynamic performance and comfort over long distances. Used mainly on road bikes and triathlon bikes, extenders allow you to adopt a more elongated and aerodynamic position, thus reducing wind resistance and improving pedaling efficiency.
In this article, we'll explore the benefits of installing handlebar extenders and why these accessories have become the equipment of choice for riders looking to optimize their performance.
1. What is a handlebar extender?
Handlebar extenders, also called triathlon bars or aerobars, are extensions that attach to the main handlebar of a bicycle, usually a racing handlebar. They allow the cyclist to lean on their forearms while placing their hands in front, in an elongated, streamlined position. The main purpose of this posture is to reduce air resistance, which is crucial during time trials or triathlons.
Extenders often come with cushions to rest the forearms, improving comfort during long rides or high-intensity events.
2. The benefits of handlebar extenders for cyclists
Adding extenders to a handlebar provides several significant benefits for cyclists, whether in terms of performance, comfort or handling.
a. Aerodynamics and speed gain
The main advantage of extenders is that they allow you to adopt an aerodynamic position by lowering your body and extending your arms. By reducing the frontal surface area exposed to the wind, the rider minimizes air resistance, resulting in increased speed without additional effort.
This posture is particularly beneficial during time trials, triathlon events or flat segments where speed is essential. Indeed, reducing aerodynamic drag can result in significant time savings, making it a major advantage for competitors.
b. Reduced fatigue
Handlebar extenders allow you to vary the position of your hands and arms, thereby reducing fatigue over long distances. Rather than maintaining a constant grip on the racing handlebars, the rider can rest their arms on the cushions and adopt a more relaxed posture, relieving strain on the wrists and shoulders.
This lying position also helps redistribute body weight, avoiding back or shoulder pain that can occur during long rides with a conventional grip on the handlebars.
c. Improved pedaling efficiency
By adopting a more elongated position thanks to the extenders, the cyclist can optimize their pedaling efficiency. The new posture improves body alignment and maximizes the power transmitted to the pedals, while reducing air resistance.
This results in improved endurance and average speed, especially on long stages where every pedal stroke counts.
3. What types of riders should install extenders?
Handlebar extenders aren’t just for professional cyclists. Several types of cyclists can benefit from this accessory, depending on their objectives and their practice.
a. Competitive cyclists
Extenders are particularly popular with competitive cyclists, especially those participating in time trials or triathlons. For these disciplines where speed is essential, extenders offer a clear advantage in terms of aerodynamics and time savings. Many models also allow precise adjustments to adapt to the cyclist's body shape and maximize comfort.
b. Cycle tourists
Cycle tourists who travel long distances may also benefit from extenders, as they allow variation in arm position and reduce fatigue. Although aerodynamics is not their main priority, the comfort they provide during long outings is a significant asset.
c. Amateur cyclists looking to improve their performance
Even recreational cyclists can benefit from extenders if they are looking to improve their performance on flat or downhill segments. Extenders allow you to adopt a more streamlined position and improve pedaling efficiency, which can result in higher speeds with less effort.
4. Installing the extenders on a handlebar
Installing extenders is relatively simple, but it must be done carefully to ensure maximum comfort and safety. Here are the main steps to follow to correctly install your extenders on your handlebars.
a. Choosing extensions suitable for your handlebars
There are several types of extenders, designed to fit different racing handlebars. Make sure the diameter and compatibility of the extenders match your handlebars, and choose a model that allows you to adjust the position of the arms and the angle of the pads for optimal comfort.
b. Position adjustment
The position of the extenders must be adjusted according to your body shape and driving style. Cushions should be placed under your forearms to provide good support without creating undue pressure, and extenders should provide a natural, comfortable grip, with straight alignment between your arms and shoulders.
c. Secure extenders
It is essential to properly attach the extenders to your handlebars following the manufacturer's recommendations. Use a torque wrench to meet the recommended tightening torques, especially if your handlebars are carbon. Over-tightening could damage the handlebars, while under-tightening could result in unwanted movement or lack of stability.
5. Precautions to take with extenders
Although extenders offer many benefits, they require certain precautions to ensure safe use.
a. Limited use in groups
One of the main limitations of extenders is that they reduce access to the brakes, since the hands are placed in front of the handlebars. This can be a problem on group rides or in urban environments where frequent stops are necessary. Extenders are therefore mainly recommended for time trials or solo journeys.
b. Gradual adjustment
If you have never used extenders before, it is advisable to gradually get used to this new position. The more elongated posture can place different demands on your muscles, and it is important to find an adjustment that allows you to avoid unnecessary tension.
6. What accessories should I add with the extenders?
To further enhance your experience with extenders, there are additional accessories that can optimize your comfort and performance.
a. Additional cushions
Forearm cushions are often supplied with extenders, but it is possible to add more padded or ergonomic models to further improve comfort, particularly over long distances.
b. Meter brackets
Some extenders have built-in mounts for a computer or GPS, keeping your electronic devices within sight without compromising your posture. This helps you monitor your speed, cadence or route while staying focused on the road.
c. Adjustable extenders
Some adjustable extender models allow you to change the length and angle of the bars to perfectly suit your needs. These models are particularly useful for cyclists who want to customize their equipment according to their performance or comfort goals.
Conclusion
Handlebar extenders are a great investment for cyclists looking to improve their performance and comfort, whether for triathlon competitions, time trials or long touring rides. Thanks to their ability to optimize aerodynamic position and reduce fatigue, they are a valuable asset for those who want to gain speed while preserving energy over long distances.
If you want to adopt a more efficient posture and reduce air resistance, installing extenders on your handlebars is a simple and effective solution that will allow you to improve your performance, while enjoying increased comfort when riding. your outings.
