AR40 Front Wheel

The AR40 is the latest addition to the Foundation lineup. Featuring an aerodynamically optimized 40mm rim depth front and rear with a 25mm internal rim width, the AR40 is designed to deliver ultimate versatility for the road ride and racer looking for performance on and off-road.

• The AR40 features ENVE’s reliable carbon construction with patent pending Wide Hookless Bead, which is a design element at the leading edge of the rim that dissipates impact energy and reduces the likelihood of pinch flatting your tubed or tubeless tire
• Ultimate versatility for the on and off-road rider
• In line with the SES wheel family, the AR40 was tested and developed in the Mercedes-Benz Formula One wind tunnel to achieve real-world aerodynamic performance
• Molded Spoke Hole Technology offers a variety of benefits that ultimately result in a more durable and reliable carbon fiber rim and wheel
• Hookless/Straight-Sidewall Design - Tubeless performance depends on the tire maintaining a light press-fit with the rim on the rim’s bead seat diameter. ENVE chooses a hookless tubeless rim profile as it allows for the critical tolerance at the rim’s bead seat diameter to be both consistent and accurate
• The AR40 is designed for use with only tubeless tires greater than 28 mm wide
