I'd rather check my measurements firstThe Mantis System turns your CarboXtrem Aero aerobars into a single centred bar, like the ones professional riders use in time trials.
By bringing your hands together it cuts frontal area and improves aerodynamic efficiency, gives you more control on descents and lets you shift your position comfortably on long rides.
Developed with HTPA‑CF25, a high-performance technical polymer used in aerospace, which offers:
Designed and made in Spain, like every CarboXtrem component.
