How To Install Aero Bars

If you're looking to enhance your bicycle's aerodynamic performance, installing aero bars can make a significant difference. Aero bars, also known as aerobars or triathlon bars, allow you to adopt a more aerodynamic position, reducing wind resistance and improving speed. Whether you're preparing for a race or just want to enjoy a more streamlined ride, knowing how to properly install aero bars is essential. This guide will walk you through the step-by-step process of installing aero bars on your bike safely and effectively.

Tools and Materials Needed

• Aero bars kit (including main bars, extensions, pads, and mounting hardware)
• Allen wrenches or hex keys (usually 4mm, 5mm, or 6mm sizes)
• Screwdriver (if required for specific mounting hardware)
• Measuring tape or ruler
• Bike torque wrench (recommended for precise tightening)
• Anti-seize compound or lubricant (optional, for easier installation)
• Marker or chalk (for marking positions)

Step 1: Prepare Your Bike and Aero Bars

Before beginning the installation process, ensure that your bike is clean and stable. If necessary, remove any existing handlebar accessories or mounts that might interfere with the aero bars. Carefully inspect the aero bars kit and familiarize yourself with all components, including the main bars, extensions, mounting brackets, pads, and hardware. Read the manufacturer's instructions included with your aero bars, as specific models may have unique installation steps or requirements.

Step 2: Remove Existing Handlebars (If Necessary)

Most aero bars are installed in place of your existing handlebars. To do this:

• Loosen the stem bolts using the appropriate Allen wrench or screwdriver.
• Carefully remove the current handlebars from the stem.
• If your bike uses a clamp-on stem, ensure you keep all hardware in a safe place for reassembly or future use.

Note: If your bike has integrated handlebar and stem components or proprietary systems, consult your bike’s manual or seek professional assistance before removing parts.

Step 3: Attach the Aero Bar Mounting Brackets

Most aero bars come with mounting brackets designed to clamp onto your existing stem or handlebars. To attach these:

• Position the mounting brackets onto your stem or handlebar area, aligning them as specified by the manufacturer. Typically, they are placed directly onto the stem clamp area.
• Adjust the brackets so they are centered and at a comfortable angle for your riding position.
• Use the provided hardware (bolts, nuts, or clamps) to secure the brackets tightly. Use an Allen wrench or screwdriver as required.
• Ensure the brackets are snug but not overtightened to avoid damaging your bike’s components.

Tip: Use a torque wrench to tighten bolts to the manufacturer’s recommended torque specifications for safety and durability.

Step 4: Install the Aero Bars onto the Mounting Brackets

With the brackets securely in place, proceed to attach the main aero bars:

• Slide the aero bars onto the mounting brackets, aligning the attachment points. Many aero bars have a clamp or bolt system for this purpose.
• Adjust the position of the bars to your preferred length and angle. Typically, the extensions should extend forward, and the pads should be positioned comfortably for your forearms.
• Secure the bars onto the brackets using the provided hardware, tightening bolts evenly to prevent misalignment.
• Verify that the bars are firmly attached and do not move when subjected to gentle pressure.

Step 5: Adjust the Aero Bar Extensions and Positioning

Proper adjustment of the extension length and angle is crucial for comfort and aerodynamics:

• Determine your optimal reach: your arms should be comfortably extended without overreaching or straining your shoulders.
• Most aero bars have adjustable extensions that can slide in or out. Loosen the extension clamps, adjust to your desired length, then re-tighten.
• Adjust the angle of the extensions to a position that feels natural and helps maintain a streamlined posture.
• Ensure that the extensions do not interfere with brake levers, shifters, or other cockpit components.

Tip: Use a measuring tape or ruler for consistent extension lengths on both sides, ensuring symmetry.

Step 6: Install and Position the Arm Pads

The pads provide support for your forearms and help maintain an aerodynamic position. To install:

• Place the pads onto the designated mounting points on the aero bars.
• Adjust the height and position of the pads to ensure comfort and support during your ride. Your elbows should be supported comfortably, and you should be able to maintain an aerodynamic posture without strain.
• Secure the pads using the hardware provided, tightening bolts evenly.
• Test the position by placing your forearms on the pads and ensuring a comfortable, natural reach.

Step 7: Final Checks and Safety Precautions

Before taking your bike for a ride, perform a thorough inspection:

• Double-check all bolts and screws, ensuring everything is tightened to the specified torque.
• Ensure the aero bars do not interfere with your brake and shifter cables.
• Test the stability of the entire setup by applying gentle force to the bars and extensions.
• Check that the pads are securely attached and provide adequate support.

It’s also a good idea to take a short test ride to ensure comfort and proper handling. Make adjustments if necessary, especially to the reach, height, or angle of the aero bars.

Conclusion

Installing aero bars can significantly improve your cycling performance by reducing wind resistance and allowing you to maintain a more aerodynamic position. The process, while straightforward, requires attention to detail to ensure safety and comfort. With the right tools, some patience, and careful adjustment, you can successfully install aero bars on your bike and enjoy the benefits of a more streamlined ride. Remember to regularly check the tightness of all hardware and make adjustments as needed to keep your setup secure and comfortable for every ride.
