ENVE Foundation AR40 Wheelset

Season:2026

Brand:Enve

Code:EN10011FAR4000

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

Borrowing from the company's proven SES rim design knowledge, the AR40 is aerodynamically optimised for 29mm - 30mm tyres and delivers drag reduction that punches well above its depth and price point. While designed primarily for on-road performance, the AR40 has been tested and qualified to ENVE’s gravel standards to ensure safety and speed for gravel riding and racing applications. The wide range of capabilities make the AR40 a perfect upgrade to any modern road bike, all-road bike, or gravel racing bike.

As with all modern wheels, the key focus is aerodynamics.
Aerodynamics are an unalienable right for road cyclists, triathletes, and now gravel riders and racers. However, not all aerodynamic performance is created equal and the best rim shapes allow for greater efficiency and confidence inspiring handling, regardless of the wind conditions. With nearly two decades of experience in developing the world’s fastest wheels, ENVE are uniquely qualified to deliver best-in-class aerodynamics to the Foundation level.

AR40 Aero


Like ENVE's SES wheel family, the Foundation Collection and the AR40 has been tested at the Mercedes-Benz Formula One Wind Tunnel to deliver best-in-class real world aero performance.

Like all ENVE’s rims, the AR40 was developed in-frame and tested at multiple speeds, 20 mph/32kph for realistic non-racer comparability, and 30mph/48kph. This testing, while more time consuming and costly, ensures that the AR40 delivers a performance advantage to riders of all abilities. As you can see, the AR40 delivers greater real world aero advantage than deeper wheels of comparable cost.


Real World Aero

The AR40 are quintessentialy ENVE and employ much of the technology used in the company's SES range. One of the defining manufacturing processes that immediately set ENVE apart is the use of their patented molded spoke hole. Rather than forming the carbon rim and then drilling the spoke holes, Enve developed a molding process that avoids drilling altogether. By doing so, Enve rims benefit from the inherent strength of long runs of unbroken carbon fibres, allowing for higher tension on spokes, less liklihood of spoke pull-through and subsequently, stiffer wheels that deliver your power more efficiently and flex less - eliminating the associated stresses. In addition, the process yields a lighter rim for the same strength.

The AR40 rims are manufactured in the US and are built by hand in the UK in order to maintain the exacting quality standards that they are renowned for. The Rims are laced onto Enve's new INNERDRIVE Foundation hub. The 24 hole hubs (front and rear) feature oversized steel ratchets, positioned inboard and over the bearings reducing stress on the axle and bearings while ensuring positive and reliable engagement.

Additional benefits are a 100% ENVE designed oversized 42mm ratchet drive system, longer bearing life through less axle stress and subsequent bearing drag. Enve's 'Perfect Preload' delivers automatic preload adjustment that helps to contribute to the hub's low maintenance & easy serviceability

As with other Enve Wide Hookless Bead rims, the Foundation AR40 benefit from the wider element in the rim profile that dissipates impact energy and reduces the likelihood of pinch flatting your tubed or tubeless tyres. In combination with the dedicated Tubeless construction, the AR40 wheels offer all the benefits of the tech - optimised. Low rolling resistance from the lack of tube-tyre interface; the riders choice of pressure to maximise comfort, traction, and rolling efficiency - which combines with the hookless bead to deliver safer, more reliable, and ultimately proper tyre fitment.

The AR40 is a versatile all-road wheel that derives much of its tech from ENVE's premium wheel lines while delivering authentic ENVE ride quality, aerodynamics, and reliability at an accessible price point.
