The **Profile Design Aerobar Riser Kit** allows you to dial in your optimal bike fit by adjusting the stack height of your Profile Design aerobars. Ideal for time trialists and triathletes, the riser kit not only enhances comfort and aerodynamics but also helps reduce drag when compared to increasing height via steerer tube spacers.

Available in various stack heights including 30 mm and 70 mm, these precision-engineered risers are constructed from forged and machined alloy and come with marine-grade steel bolts designed to withstand high clamping forces.

• Improves aerobar stack height for optimized fit and comfort
• Wind tunnel tested: riser stacks reduce drag more effectively than steerer spacers
• Forged and machined alloy construction for strength and weight savings
• Marine-grade steel bolts ensure durability under stacked load
• Available in multiple heights: 30 mm and 70 mm
