The Bontrager Aeolus Pro 37 carbon wheelset strikes a smart balance between lightweight climbing performance and aerodynamic efficiency, making it a versatile choice for everything from punchy road races to mixed-surface adventures. With a 37mm depth and a 21mm internal width, the Pro 37s are wide enough to support modern tire profiles—road or gravel—without adding unnecessary mass. Built with OCLV carbon and laced to smooth-rolling Bontrager hubs, they offer a responsive, stable ride with confident handling in crosswinds. Tubeless-ready out of the box and built to take a beating, the Aeolus Pro 37s are an easy upgrade for riders who want pro-level performance without the premium price tag.
