Monarch Integrated Aerobar



The Monarch is a universal integrated aerobar designed to be the complete solution to the needs of modern triathletes and time trialists.

The Monarch gives a solution to three key areas athletes demand from a premium integrated aerobar: wide adjustment range, functional internal cabling, and world class aerodynamics. Conventional arm cups and extensions mount to a platform atop a height adjusting central post. Pad stack, pad reach, and arm tilt can each be adjusted in isolation which makes it a dream for bike fitters and athletes seeking the perfect position. Reach a new level of comfort and speed thanks to the superior ergonomic and aerodynamic capabilities of the Monarch Integrated Aerobar.

Features include:

  • Functional and effective integrated stem cover completely conceals internal cabling while allowing quick access for maintenance
  • Flush-mount Shimano Di2 junction box and charging port is easily accessible for fast battery charging or firmware updates
  • Mono stack adjustment post makes pad height changes easy. Singular leading edge reduces drag and improves aerodynamic performance
  • Pad Stack, Reach, Tilt, and Width can be adjusted individually making for convenient fitting and position changes
