10 Best Aero Bars For Road Bike 2025 in the United States

The VISION Trimax Carbon Si 013 Aerobar is designed specifically for triathlon and time trial bikes, featuring a JS-bend style handlebar which offers a comfortable ergonomic position suited for aerodynamic riding. Made from carbon, it keeps the weight low, which is ideal for riders wanting to minimize bike weight without sacrificing stiffness.

Adjustability is a key strength here, as the bars can be fine-tuned to fit individual arm positions and preferences, helping improve comfort during long rides. The armrests provide good support, although they may not have extensive padding compared to some more expensive models, so comfort may vary based on personal preference. Compatibility-wise, it fits standard 31.8mm clamp sizes, making it easy to attach to most road bike setups.

This model has been available since 2009, so it might not include some features found in newer aero bars. Nevertheless, its solid construction and carbon material make it a reliable choice for triathletes seeking a lightweight and adjustable aero bar setup without a steep learning curve.

The Profile Design Legacy II Aerobars are a solid choice for cyclists looking to enhance their aerodynamics during triathlons, time trials, or long rides. One of the standout features is the ergonomic design, which includes Venturi-style armrests that promote comfort and allow for multiple hand positions. This can help reduce fatigue on longer rides, which is a significant advantage for endurance athletes. The aerobars are also adjustable, allowing users to customize the width and angle of the armrests to suit their riding style, making it easier to achieve a comfortable and effective riding position.

Weighing in at just 450g, the Legacy II is lightweight, which is beneficial for performance-focused riders aiming to maintain speed without added bulk. They are made from durable 6061-T6 aluminum, ensuring they can withstand the rigors of both training and competition.

On the compatibility front, these aerobars fit 31.8 mm handlebars and can be adapted for 26.0 mm with additional shim kits, giving them some flexibility for different bike setups. However, it's important to note that they are not intended for use with Aerobar Bracket Riser kits, which may limit some users' options.

The REDSHIFT Quick-Release Clip-On Bike Aero Bars are a solid option for cyclists seeking to enhance their riding position, particularly for road and triathlon use. One of the standout features is the patented quick-release mechanism, allowing riders to switch between road and aero positions with ease during their ride. This flexibility is great for those who want to adapt their riding style without stopping or dealing with tools, making it very user-friendly.

Adjustability is another strong point; these aero bars offer a wide range of settings for arm pad height, width, and extension length, catering to different rider sizes and preferences. This can significantly improve comfort during longer rides, as fine-tuning the fit is crucial for maintaining a good riding posture.

Weight-wise, at 0.82 kilograms, they are relatively lightweight, which is beneficial for performance-oriented cyclists. However, it’s important to note that while they fit standard handlebar diameters, specific shims are needed for 26.0 mm handlebars, which could be an additional consideration for some riders.

On the downside, while the quick-release feature is convenient, it may not inspire confidence in terms of stability for all users; some might prefer a more permanent setup for long-distance cycling. Additionally, the requirement for extension risers, sold separately, could be a drawback for those looking for a complete package right out of the box. These aero bars are well-suited for road cyclists and triathletes who value versatility and adjustability and don’t mind the additional purchase of accessories for a complete setup.
