Product Information

Full details

The Easton EC70 Aero Handlebar is designed for road cyclists who prioritize aerodynamic efficiency without sacrificing long-ride comfort. Built with carbon fiber monocoque construction, it is ideal for competitive riders and enthusiasts looking to upgrade their cockpit; however, the integrated design requires careful consideration of cable routing and stem compatibility compared to standard round bars.

FAQs

What is the clamp diameter for these handlebars?

The Easton EC70 Aero uses a standard 31.8mm clamp diameter.

Are these handlebars compatible with Di2 internal battery routing?

Yes, the internal design is capable of accommodating electronic shifting wires.

Can I use clip-on aero bars with these?

Due to the flat aerodynamic top section, most standard clip-on aero bars are not compatible. Always check the specific compatibility requirements of your aero extensions.

What does the reach and drop measurement mean?

The reach (80mm) is the distance from the center of the stem clamp to the farthest point of the bar, and the drop (125mm) is the vertical distance between the top of the bar and the bottom of the drops.

Is carbon paste required for installation?

Yes, carbon assembly paste is highly recommended to ensure the bars stay secure at lower, safer torque values.

Troubleshooting

Handlebars slipping in the stem clamp

Ensure the clamping area is clean, re-apply high-quality carbon friction paste, and verify the torque spec is met using a calibrated torque wrench.

Difficulty with internal cable routing

Use a professional cable routing tool or a thin fishing line and magnet kit to guide housing through the internal ports.

Pros and Cons

Pros

  • Excellent vibration damping properties for increased comfort
  • Lightweight carbon construction improves overall bike handling
  • Aerodynamic top shape reduces drag significantly
  • Well-proportioned reach and drop dimensions
  • Stiff construction translates to efficient power transfer during sprints

Cons

  • Not compatible with all clip-on aero bar extensions
  • Requires careful installation to avoid over-tightening carbon parts
  • Higher price point compared to aluminum equivalents
  • Internal routing can be challenging for inexperienced mechanics

Setup, Compatibility & Care

When installing the EC70 Aero, use a torque wrench to stay within the manufacturer's specified limits, as carbon components are sensitive to overtightening. Always apply carbon friction paste at the stem-to-handlebar interface to prevent slippage. The bar is designed for a 31.8mm stem clamp diameter. For maintenance, clean the surface with a soft, damp cloth and mild soap; avoid harsh chemical solvents that can degrade the clear coat or resin. Periodically inspect the bar for any signs of surface cracks, especially around the stem clamping area, following a crash or hard impact.
