ENVE AR40 Foundation Series Wheel

The ENVE AR40 Foundation wheels feature a hookless bead design, which is specifically engineered for tubeless setups. While you can technically use a tubeless-compatible inner tube with a tubeless tire, you must ensure the tire manufacturer explicitly approves the use of tubes with their hookless-compatible tires.

The 25mm internal width is optimized for higher-volume tires, typically ranging from 28mm to 45mm. This width provides excellent sidewall support, allowing you to run lower pressures for better traction and comfort on mixed surfaces.

No, the ENVE AR40 Foundation wheels are designed exclusively for disc brake systems. They feature a Centerlock rotor interface and are built for 12x142mm thru-axle spacing.

The 40mm profile is designed to balance aerodynamic efficiency with handling stability. While deeper than a standard box-section rim, it is shallow enough to remain predictable and manageable in gusty conditions compared to deeper aero wheels.

The molded spoke holes are designed to maintain consistent spoke tension over time, reducing the need for frequent truing. Aside from standard periodic checks to ensure spokes remain tight, they require no specific maintenance beyond what you would perform on any high-performance wheelset.
