Aero & Adventurous Carbon Bars From Canada's Finest Component Makers

The Easton EC90 AX Carbon Handlebars push the boundaries of adventure cockpits. Not only are they meant to take a beating, but they also are constructed to reduce air drag with their aerodynamic top bar shape. These factors combined with its ultralight weight and flared ergonomic shape, these bars are meant for the podium.

This EC90 is the lightest option in Easton's AX lineup, and they feature compatibility with bar-end mounted Di2 junction boxes. Its comfortable reach offers ideal hand positions and the drop flares out to 16-degrees for greater control and leverage on techier sections of gravel and singletrack. Suffice it to say, these bars provide excellent handling for anything from bikepacking to gravel racing.


  • Lightweight carbon construction for an optimal strength-to-weight ratio
  • A perfect upgrade to any gravel or cyclocross bicycle
  • Made for 31.8mm stem clamps
  • Flared 16 degree drops provide more control and leverage than traditional bars
  • Top bar shape provides an aerodynamic advantage
  • Compatible with Di2 junction boxes

Best Handlebar Ever

This handlebar went on my BMC Kaius three and it was a great improvement over the aluminum bars that came with the bike. I feel it's a great upgrade for a gravel bike. Their 16 degree flare drop is perfect also and very comfortable for long rides.
