When you're in it to win it, you need Profile Design's Aeria Integrated Aero Bars! Designed for maximum aerodynamics, amazing adjustability and superior handling, this beautiful front end sets a new standard. For the ideal blend of power, control and aerodynamics it boasts Profile's high-modulus carbon wing base bar with ergonomic grips, stackable risers for fine-tuning armrest and extension height, their F25 armrests that can be rotated and moved fore/aft, and their T2+ carbon extensions that also are fully adjustable. This all means that you can dial in the ultimate fit to fly down the road and change it as you get stronger, more flexible and even faster! Plus, the carbon construction means lightness and stiffness for excellent support and handling when you're hammering along setting a new PR. And, to make your bike cheat the wind even more you also get multiple drillings for internal cable routing and Di2 compatibility (electric-shifting components that use wires).
