Best aero bars

Adding aero bars to a road bike provides multiple benefits for triathletes. These bars result in improved aerodynamics, increased speed, and better endurance. And, most importantly, you won’t have purchased a triathlon bike, as most of these bars can clip onto a road bike.

Here, we’ll explore top-rated aero bars for road bikes:

Profile Designs Legacy II Aerobar

The Legacy II Aerobars are adjustable, allowing you to modify the width between the bars, the bar angle, and the rotation of the arm pads. I found this particularly helpful as I was able to customize the aerobars to my comfort level. Initially, I had them set at a wider separation and later brought them in tighter for a more aerodynamic and slightly less comfortable position.

Installing the aerobars was quite easy, even on my 26mm handlebars. The package included shims, which ensured a perfect fit without any issues. Although some triathletes have reported difficulties with the short screws provided, I didn’t encounter any problems during installation.

One aspect I appreciated was the curved bars, which provided multiple comfortable hand positions. During my rides, the aero bars remained stable and secure, even on longer distances. The armrest pads were comfortable, and the overall design of the aero bars felt lightweight yet sturdy.

In terms of performance, the Legacy II Aerobars exceeded my expectations. I noticed a considerable improvement in my speed and comfort during the bike leg of my triathlon. The aerodynamic position allowed me to put more power into my pedaling, resulting in faster times and increased efficiency.

However, there is a minor drawback to consider: the aero bars may not be easily removable and reinstalled while keeping the mounting bracket attached to the handlebar. This means that you will need to remove the mounting bracket from the handlebar to remove the aero bars completely. For some users, this might not be an issue, but it is worth noting.

In conclusion, the Profile Designs Legacy II Aerobar is an excellent investment for triathletes seeking to improve their bike leg performance. The adjustable design, easy installation, and comfortable hand positions make these aero bars a valuable addition to any triathlon setup. Based on my experience, I highly recommend giving them a try.

The adjustability of these aero bars is one of their standout features. They offer numerous adjustment options, including reach, height, and arm pad location. This level of customization makes them suitable for both short and long-course triathlons, as well as casual riding or commuting.

These aero bars are compatible with most road bikes, thanks to their 31.8mm clamp diameter. However, it’s important to note that they may not be suitable for carbon handlebars or those with an elliptical shape.

One aspect that I particularly appreciate is the comfort provided by the thick arms pads. I’ve found that the padding helps to alleviate arm and neck pain, even on long rides over 120 miles. The bars themselves are sturdy, providing a solid and stable feel when riding in the aero position.

While there are lighter options available, such as carbon fiber aero bars, these Profile Designs bars offer a great balance between performance, comfort, and affordability. I would recommend purchasing the riser kit to further customize your fit and increase comfort.

In conclusion, the Profile Designs Sonic/Ergo/4525a Aerobar is a versatile and adjustable option for triathletes seeking improved aerodynamics and comfort on their road bikes. With their sturdy construction, extensive adjustability, and comfortable arm pads, these aero bars have proven to be an excellent investment in my triathlon journey.

One of the key advantages of this product is its compatibility with various bikes. However, it may not fit on certain bike models like the Giant Disc Road Bike with hydraulics in the middle of the handlebars. In such cases, modifications to the brake system might be necessary.

The armrests offer multiple positions for adjustment, allowing users to customize their fit for maximum comfort. The pads on the armrests are attached using Velcro, which adds another layer of adjustability.

As for installation, the Airstryke V2 is relatively easy to install. However, some triathletes might face difficulty in adjusting the distance of the bar once it is attached. A bike stand or assistance from another person may be needed for proper installation.

One potential drawback to this product is the slipperiness of the armrests when they get wet or sweaty. Some triathletes have reported issues with the armrests becoming slippery in humid conditions, which may affect stability and control during a ride. To address this issue, you may consider using absorbent or wicking covers or applying tape to the bars where your hands rest.

Overall, the Profile Designs Airstryke V2 is a great aero bar. With its adjustable armrests and comfortable design, it can greatly improve your riding experience. Just be mindful of the potential slipperiness of the armrests and make necessary adjustments to ensure a safe and enjoyable ride.

Choosing the right TT bar

Here’s a detailed guide to help you make the best decision:

1. Fit and adjustability: The ideal aero bar should accommodate your body dimensions and preferred riding position. Look for aero bars with multiple adjustment options for the armrests, extension length, and extension angle. This will allow you to fine-tune your position for optimal comfort and performance.
2. Compatibility: Ensure the TT bar you select is compatible with your road bike’s handlebar diameter and stem. Most aero bars are designed to fit handlebars with a 31.8mm clamp diameter, but it’s crucial to verify before making a purchase.
3. Weight: The weight of the aero bar can impact your overall bike performance. Lighter aero bars made from carbon fiber or aluminum offer better aerodynamics without adding unnecessary weight. However, lighter materials often come at a higher cost.
4. Extension shape: Aerobar extensions come in various shapes, including straight, S-bend, J-bend, and ski-bend. Each shape caters to specific rider preferences and comfort levels. Test different extension shapes to determine which suits you best.
5. Armrest comfort: Comfortable armrests are essential for long rides. Look for aero bars with well-padded armrests and the ability to adjust their width, height, and angle.
6. Integration of accessories: Some aero bars have integrated features like hydration systems or computer mounts. Consider whether you need these additional components, and select a TT bar that allows for seamless integration.
7. Ease of installation and removal: If you plan to switch between using aero bars and riding without them, look for a model that is easy to install and remove. Quick-release or clip-on aero bars are perfect for this purpose.
8. Budget: Aerobars range in price, with more expensive models typically offering advanced features, lighter materials, and increased adjustability. Determine your budget and balance the cost with the features you need for your specific riding style and goals.

By taking these factors into account, you can make an informed decision when choosing the right TT bar for your road bike. Remember that the ideal aerobar should provide a balance of comfort, aerodynamics, and adjustability, while also being compatible with your bike and budget.
