Full details

FAQs

What is the clamp diameter for these handlebars?

These handlebars are designed for a standard 31.8mm stem clamp.

Can I use clip-on aero bars with these handlebars?

It is generally not recommended to mount clip-on aero bars on carbon handlebars unless specifically approved by the manufacturer, as the clamping force can damage the structure.

Do I need special tools to install these?

Yes, a torque wrench is essential to ensure the carbon is not damaged during installation.

What does UD carbon finish mean?

UD stands for Unidirectional carbon fiber, which provides a clean, matte aesthetic look while maintaining high structural strength.

What are the reach and drop measurements?

These bars feature an 80mm reach and a 125mm drop.

Troubleshooting

Handlebars slipping in the stem clamp

Verify the torque settings. Apply carbon assembly paste to the contact area and ensure the faceplate is tightened evenly in a cross pattern.

Creaking sounds during out-of-the-saddle climbing

Clean the interface between the stem and the bar, re-apply friction paste, and re-torque the stem bolts to the recommended factory specification.

Pros and Cons

Pros

  • Excellent balance of stiffness and vibration dampening
  • Proven aerodynamic profile reduces wind drag
  • Ergonomic geometry promotes comfortable hand positions
  • High-quality carbon construction ensures long-term durability

Cons

  • Specific 44cm size may be too wide for smaller riders
  • Requires proper torque tools to avoid damaging carbon
  • Limited adjustment range compared to flat-top bar alternatives

Setup, Compatibility & Care

Installation of the Easton EC70 Aero requires basic knowledge of bicycle maintenance, specifically involving carbon components. Ensure your stem uses a 31.8mm clamp size and that the faceplate is free of sharp edges that could score the carbon. Always use a calibrated torque wrench and follow the manufacturer's torque specifications to prevent structural failure. Apply a small amount of carbon-specific friction paste to the clamping surfaces to ensure a secure fit without over-tightening. For care, clean the bars periodically using mild soap and water; avoid using abrasive solvents or cleaners that may damage the matte UD finish. Periodically inspect the bar for any signs of surface cracking or deep scratches, especially after a crash.
