Get clean lines and responsive steering with the PRO Vibe Carbon Handlebar. It's unidirectional carbon construction balances strength, stiffness, and low weight for precise handling on technical descents and high-speed sprints. PRO adds high-performance Innegra fiber to the carbon mix to further strengthen the bar's most vulnerable areas without adding weight, so the bars are ready to float over cobble-strewn roads or even a 'cross race. The Vibe's compact shape puts the drops within easy reach to promote comfortable hand positions at all points on the bar.The Vibe incorporates a round upper profile for easy compatibility with bar accessories, such as computer mounts and lights, and comfort. As a subsidiary of Shimano, PRO bars are compatible with the new bar-end mounted Di2 junction box, which sits at the end of either drop instead of a bar plug. The internal cable ports let you feed E-Tube or mechanical shift housing as well as hydraulic or regular brake housing through the system.
