RATED FOR GRAVEL

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. Its wide range of capabilities make the AR40 a perfect upgrade to any modern road bike, all-road bike, or gravel racing bike.

AERODYNAMIC PERFORMANCE

Aerodynamics are an unalienable right for road cyclists, triathletes, and now gravel riders and racers. 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, we are uniquely qualified to deliver best-in-class aerodynamics to our entire product line.

INNERDRIVE FOUNDATION HUBS

INNERDRIVE™ represents the pinnacle of bicycle drive mechanisms. Oversized steel ratchets are positioned inboard and over the bearings reducing stress on the axle and bearings while ensuring positive and reliable engagement.

• 100% ENVE Designed oversized 42mm 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

WIDE HOOKLESS BEAD

Potholes and unforeseen impacts are part of life, but that doesn’t mean they need to ruin your ride. The AR40 features ENVE’s 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 tyre.

Tubeless performance depends on the tire maintaining a light press-fit with the rim on the bead seat diameter. ENVE chooses a hookless tubeless rim profile as it allows the rim’s critical tolerance at the bead seat diameter to be both consistent and accurate. In short, hookless is chosen to deliver a safer and more reliable tubeless system.
