The LOOK Combo Aero Carbon Handlebar uses a carbon fiber construction with aerodynamic shaping across the tops, drops, and extensions. The handlebar features a flattened top section that reduces frontal area and integrates with LOOK's Combo Aero stem design. The drops use a compact bend geometry that shortens the reach from the hoods to the lower grip position. The carbon layup provides the structural requirements for handlebar forces while reducing weight compared to aluminum bars.

The handlebar uses a 31.8mm center clamp diameter, which is standard for modern road stems. The drop sections taper outward to accommodate bar tape and provide grip area for hand positions. The tops are shaped to integrate cable routing systems, with grooves or channels that guide housing along the handlebar before entering the frame or stem. The handlebar is designed to work with LOOK's TiCR internal cable routing system, though it functions with external routing setups as well.

This handlebar is optimized for integration with LOOK's Combo Aero stem and frame designs, where the handlebar profile aligns with the stem and head tube to create a continuous aerodynamic shape. The compact drop geometry suits riders who prefer shorter reach distances when transitioning from the hoods to the drops. The handlebar accommodates standard brake and shift lever installations for road groupsets.
