The ENVE Foundation AR40 is an elite carbon wheelset built for versatility across road and gravel surfaces. With an aerodynamically optimized 40mm rim depth and a 25mm internal width, these wheels are engineered for everything from smooth asphalt to rugged paths.

Tested to ENVE’s strict gravel standards, the AR40 provides a responsive ride while Wide Hookless Bead technology reduces pinch flat risks. Built with Sapim CX-Ray spokes and INNERDRIVE hubs, it balances lightweight performance with long-term durability.

The tubeless-only design is optimized for 27mm tires but handles widths up to 50mm, making it ideal for "all-road" cyclists. At 1515g, the AR40 delivers a premium racing feel with the reliability needed for serious off-road exploration.
