1. Introduction
This manual provides essential information for the proper installation, use, and maintenance of your Easton EC70 Aero Road Handlebar. Please read this manual thoroughly before installation and retain it for future reference. The Easton EC70 Aero Road Handlebar is designed for road cycling, offering a lightweight carbon construction and an aerodynamic profile for enhanced performance.
2. Product Features
- Carbon Construction: Manufactured from high-quality carbon fiber for optimal strength-to-weight ratio.
- Aerodynamic Design: Engineered to reduce drag and improve efficiency during rides.
- 31.8mm Clamp Diameter: Standard diameter for compatibility with most modern road stems.
- Integrated Cable Routing: Designed for internal cable routing to maintain a clean aesthetic and aerodynamic profile.
3. Installation Guide
Proper installation is crucial for safety and performance. If you are unsure about any step, consult a professional bicycle mechanic.
- Prepare the Stem: Ensure your bicycle stem has a 31.8mm clamp diameter. Clean the stem clamp area thoroughly.
- Apply Carbon Assembly Paste: Apply a thin layer of carbon assembly paste to the handlebar's clamping area and the stem's clamping surface. This increases friction and reduces the required clamping force, minimizing the risk of slippage and damage.
- Position the Handlebar: Carefully place the handlebar into the stem clamp. Adjust the rotation to your preferred riding position.
- Tighten Stem Bolts: Tighten the stem faceplate bolts gradually and evenly in a crisscross pattern. Refer to your stem manufacturer's recommended torque specifications. For carbon components, it is critical not to overtighten. A torque wrench is highly recommended.
- Install Shifters/Brake Levers: Mount your shifters and brake levers onto the handlebar. Adjust their position for comfortable reach and braking. Tighten their clamps according to the component manufacturer's specifications.
- Route Cables: Utilize the internal routing ports on the handlebar for brake and shifter cables. Ensure cables are routed smoothly without kinks or excessive bends.
- Wrap Handlebar Tape: Securely wrap your preferred handlebar tape, starting from the bar ends and working towards the stem.
Warning: Always use a torque wrench when tightening bolts on carbon components to prevent damage and ensure safety. Exceeding recommended torque values can lead to component failure.
4. Usage Guidelines
The Easton EC70 Aero Road Handlebar is designed for optimal performance and comfort in various road cycling conditions. Familiarize yourself with different hand positions to maximize control and reduce fatigue.
- Tops: Provides an upright, relaxed position, ideal for climbing or casual riding.
- Hoods: A versatile position offering good control and access to brake levers and shifters, suitable for general riding.
- Drops: Offers a lower, more aerodynamic position for high-speed riding, descending, and aggressive cornering.
Always ensure your hands are securely gripping the handlebar, especially when braking or navigating challenging terrain.
5. Maintenance
Regular maintenance will prolong the life of your handlebar and ensure safe operation.
- Regular Cleaning: Clean the handlebar with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the carbon finish.
- Inspect for Damage: Periodically inspect the handlebar for any signs of cracks, dents, or stress marks, especially after any impact or fall. Carbon fiber can be susceptible to impact damage that may not be immediately visible. If any damage is suspected, discontinue use immediately and have it inspected by a professional.
- Check Bolt Torque: Regularly check the torque of the stem faceplate bolts and shifter/brake lever clamps. Re-tighten to manufacturer specifications using a torque wrench if necessary.
- Handlebar Tape: Replace handlebar tape when it becomes worn or loses its grip to maintain comfort and control.
