Free Speed

Orca Aero is Orbea's answer for riders who want to go faster for the same effort. Every tube of the OMX carbon frame is shaped to cut through the air at real-world angles, not just in the wind tunnel.

It's raced at the highest level by Orbea's pro teams, and it's built to feel fast from the first pedal stroke.

Race Bike, Road Manners

Aero doesn't have to mean harsh. Orca Aero balances stiffness and compliance so it stays composed over broken tarmac and long days in the saddle.

Wide tyres add comfort and grip without giving up speed, so it's as at home on a club run as it is on race day.

Clean, Integrated Cockpit

Cables run fully inside the carbon cockpit and frame, keeping the front end tidy and slippery.

The one-piece OC bar and stem is shaped for aero hand positions, with sizes matched to each frame for the right fit.

Storage Built In

An integrated OC storage box keeps a tube, tools and CO2 tucked out of the wind.

No saddle bag, no extra drag, and everything you need for a roadside fix is always with the bike.
