For cyclists who seek speed, precision, and aerodynamic efficiency, time trial (TT) handlebars—commonly referred to as aero bars—have become a game-changing component. Originally designed for time trials and triathlons, these handlebars are no longer reserved for elite athletes alone. If you're riding with standard road handlebars and wondering whether it's worth upgrading to aero handlebars for your road bike, you're not alone.
The good news? You don’t need to invest in a full TT bike. With modern aero bicycle handlebars, you can easily convert your road handlebar into a time trial setup. In this guide, we’ll explain the types of handlebars, how the conversion works, what equipment you’ll need, and why this upgrade might be the smartest move for your performance and comfort.
1. Understanding the Different Types of Handlebars
Before diving into the upgrade, let’s review the types of bike handlebars for road bikes to understand what you’re working with and what you're transitioning to.
| Handlebar Type | Description |
|---|---|
| Drop Handlebars | Common on road bikes; multiple grip positions; great for varied terrain |
| Flat Bar Handlebars | More upright posture; seen on hybrids or endurance bikes |
| Aero Handlebars / TT Bars | Designed for speed; reduce drag by improving aerodynamic posture |
By installing aero handlebars for road bikes, you gain many of the aerodynamic benefits of a TT bike without replacing your entire setup.
2. What Are Aero Bicycle Handlebars?
Aero bicycle handlebars (or aero bars) are either integrated into a TT frame or added as clip-ons to standard drop handlebars. They typically consist of:
-
Forward-facing extensions (0° or 15°)
-
Armrest pads
-
Adjustable mounts for width and angle
These components help cyclists reduce drag and maintain a streamlined position for long periods.
Key Benefits:
-
Improved aerodynamic posture
-
Enhanced endurance by spreading weight across forearms
-
Affordable alternative to purchasing a dedicated TT bike
-
Compatible with many road bikes
3. Can You Convert Road Handlebars to TT Bars?
Absolutely! The most common solution is using clip-on aero handlebars that mount directly to your road bike handlebar, provided it has the standard 31.8mm clamp diameter (or adapters).
Compatibility Considerations:
-
Standard Drop Handlebars: Usually fully compatible.
-
Integrated Handlebars: Check for clamp space and cable routing compatibility.
-
Flat Handlebars: Typically not suitable for aero bars due to lack of clamping surface.
Modern clip-on aero handlebars are lightweight, adjustable, and designed to work with both alloy and carbon handlebars. You can even find models with carbon extensions for ultralight performance.
4. Step-by-Step Guide to Installing Aero Handlebars
Tools You’ll Need:
-
Allen keys (usually 4mm or 5mm)
-
Torque wrench (highly recommended)
-
Ruler or tape measure
Installation Steps:
-
Positioning: Decide where you want the aero bars mounted—usually centered over the stem.
-
Clamp the Extensions: Place the clip-on clamps over the handlebar and tighten gently.
-
Attach Arm Pads: Mount the armrest pads in a position that supports your forearms naturally.
-
Adjust Angles: Choose between 0° (straight) or 15° (slightly upward) extensions based on comfort and ride style.
-
Torque Tighten: Use a torque wrench to avoid over-tightening, especially on carbon bars.
-
Test Ride: Ensure everything feels stable and make final adjustments to fit.
5. Choosing the Right Aero TT Bar for You
The market is full of options, so selecting the best aero handlebars for your road bike depends on your riding goals.
| Feature | Description |
| Extension Angle | 0° for aggressive posture, 15° for comfort and climbing |
| Material | Carbon fiber (lightweight) vs Aluminum (durable and affordable) |
| Adjustability | Fore-aft and angle adjustments for both extensions and arm pads |
| Compatibility | Check fit with road handlebar; most clip-on aero handlebars work well |
Top Use Cases:
-
Triathlon training and racing
-
Long-distance solo rides
-
Time trials or flat group rides
Example: Many Ironman triathletes use clip-on carbon aero bars on their endurance bikes to get through long-distance events with better energy conservation.
6. What to Expect After the Upgrade
Performance Gains:
-
Increased average speed due to reduced air resistance
-
Improved efficiency during flat terrain or tailwind conditions
-
Less strain on hands and shoulders on long rides
Comfort Considerations:
-
Your neck and back may need to adjust to the forward-leaning position
-
Fine-tune pad spacing and extension angle for better ergonomics
Pro Tip: Start with shorter rides and gradually build up your endurance in the aero position.
7. Pros & Cons of Aero Handlebar Conversion
| ✅ Pros | ❌ Cons |
| Inexpensive performance boost | Takes time to get used to aero position |
| Easy to install and remove | Not ideal for climbing or technical handling |
| Compatible with most road bikes | May reduce brake and shifter accessibility in aero position |
| Helps conserve energy on long rides | Requires neck/back adaptation for long-term aero posture |
8. Maintenance and Riding Tips
Maintenance Tips:
-
Regularly check bolts for tightness (especially before races)
-
Inspect for signs of wear or cracks (especially carbon bars)
-
Replace armrest pads as needed for comfort
Riding Tips:
-
Practice transitions between drop and aero positions
-
Train your core for better aero posture
-
Be extra alert in group rides (aero position reduces visibility)
