AERODYNAMICS: WIND TUNNEL TESTED, REAL-WORLD PROVEN
Aerodynamics are a non-negotiable advantage for road cyclists and triathletes—delivering greater efficiency and confidence-inspiring handling, no matter the wind conditions. With more than 15 years of experience developing some of the world’s fastest wheels, ENVE is uniquely qualified to bring best-in-class aerodynamics to the Foundation customer.
Like our SES wheel family, the AR40 was tested and developed in the Mercedes-Benz Formula One wind tunnel to achieve real-world aerodynamic performance. Unlike other wheel brands that test isolated wheels at elite speeds of 30 mph (48 kph), ENVE develops and tests wheels in-frame at multiple speeds ranging from 20 mph (32 kph) to 30 mph (48 kph).
TUBELESS: ROLL FAST, FLAT LESS
Since 2016, ENVE has been converting road riders from inner tubes to tubeless due to the numerous benefits of the system, which include:
- Lower rolling resistance – By eliminating the inner tube, the friction between tire and tube is also eliminated, allowing the tire to flex and conform to the road with greater efficiency.
- Flat less, ride more – Flat tires are a buzzkill. With a little sealant you can eliminate nearly all flats that would have been caused by an intrusive thorn or piece of debris.
- Run the Best Pressure – Tubeless means you can run the pressure you want to maximize comfort, traction, and rolling efficiency.
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.

INNERDRIVE™ HUBS
INNERDRIVE™ represents the pinnacle of hub driven bicycle mechanisms. Oversized steel ratchets are positioned inboard and over the bearings, reducing stress on the axle and bearings while ensuring positive and reliable engagement.
HIGHLIGHTS
- 100% ENVE Designed oversized 42 mm ratchet drive system
- Longer bearing life
- Reduced axle stress = less bearing drag and prolonged bearing life
- Drive component retention
- Perfect Preload – automatic preload adjustment
- Low maintenance & easy serviceability
