Profile Design Legacy II Aerobars

The Legacy II Aerobars are forged from 6061-T6 aluminum, delivering durability with Venturi-style armrests for improved aerodynamics. They offer width and rotation adjustments to customize armrest positioning, helping riders reduce fatigue on long-distance efforts. Designed for triathlons, time trials, and extended road rides, these aerobars aim to provide a secure fit while optimizing your riding position for speed and efficiency.
RXL SL Adjustable TT Rest Aero Bars

This carbon fiber aero bar set is lightweight and compatible with 31.8 mm clamps. It offers a TT rest length of 255 mm with a 15 mm adjustable extension. A sponge pad provides arm comfort, and installation guidance emphasizes a 4 Nm tightening torque for a secure fit. The combination of low weight and stiffness supports efficient power transfer while maintaining aero positioning.
BBB Cycling AeroMax Two-Piece Aero Bars

The BBB AeroMax features a two-piece aluminum construction with long J-bend bars (350 mm) and foam padding for comfort. The design prioritizes maximum aerodynamics while maintaining an adjustable hand and arm position, suitable for riders seeking a balance between speed and ride comfort on long courses.
BBB Aero Bars BHB-59 AeroComfort

These two-piece aluminum aero bars increase the rider’s aero position with a 35 mm lift, delivering a more comfortable race posture. Foam padding and protective foam sleeves around the steerer tubes enhance overall comfort and protect the bar area during intense sessions or rough roads.
REDSHIFT Quick-Release Clip-On Aero Bars

The RedShift aero bars offer a patented quick-release clip-on mechanism for rapid position changes between road and aero modes. They install and remove without tools, enabling on-the-fly position adjustments to suit varying sections of a ride, making them ideal for triathlon transitions and dynamic course profiles.
Buying Guide: Key Considerations For Triathlon Handlebars On Road Bikes
When selecting triathlon handlebars for a road bike, consider material, weight, compatibility, adjustability, and comfort. Carbon fiber options typically prioritize weight savings and stiffness, while aluminum offers durability and cost efficiency. Ensure clamp compatibility with your handlebars and stem, usually 31.8 mm, but verify your bike’s specifications. Armrest width and rotation adjustment influence reach, elbow alignment, and aerodynamics, so test different positions if possible. Padding, especially EVA or foam, reduces arm fatigue on longer rides. Quick-release mechanisms can save transition time in triathlons, but ensure reliable retention and alignment. Finally, evaluate installation torque recommendations to prevent damage and maintain safety.
Practical Comparison At A Glance
- Material: Carbon fiber vs aluminum. Carbon for light weight and stiffness; aluminum for budget and durability.
- Adjustability: Wider armrests and rotatable mounts improve fit for varied torso lengths and riding styles.
- Padding: Foam/EVA padding enhances comfort on rough roads and long segments.
- Installation: Quick-release options offer convenience but require secure mounting to prevent slippage.
- Weight: Lighter setups contribute to better acceleration and climbing efficiency, especially in triathlon courses.
Across these options, the choice depends on the balance between weight, stiffness, and ease of use. For climbers and longer events, carbon fiber with adjustable rests and comfortable padding often delivers the best aerodynamics and fatigue management. For casual or budget-conscious riders, aluminum options with solid adjustability still provide meaningful aero benefits without a high price tag.
