Description
UCI approved, straight from the pro peloton, the Argon 18 Nitrogen Pro Road Frameset is the perfect platform for building your dream race machine.
The carbon composite frame is lightweight and stiff, offering a superb ride with great power transfer and assured handling. The aero profile tubing is refined to keep the frame light. Featuring road race geometry mixed with an aerodynamic profile, this lightweight frameset offers the perfect mix for riding flats and climbs alike.
The included caliper brakes are directly mounted to key locations behind the fork and seat stays in order to keep them out of the airflow and optimise aerodynamic performance.
The drag reducing aerodynamic carbon AHB5000 cockpit reduces handlebar drag by 30%. The system boasts all the benefits of a one-piece handlebar and stem but features superior adjustability with a range of stem height and length options available on adjustment.
Provided with three headtube heights, the Nitrogen Pro can be adjusted to fit the rider while maintaining a clean look around the stem. The system uses a clever press-fit top cap and comes supplied with three height options to help you find your most comfortable position on the bike.
