The AR40 is the latest addition to ENVE’s Foundation lineup. Featuring an aerodynamically optimized 40mm rim depth, with a 25mm internal rim width, the AR40 is designed to deliver ultimate versatility for enthusiasts and pro riders alike who are looking for performance on and off-road.
“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,” boasts ENVE.
Like ENVE’s 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).
Since 2016, ENVE has been converting road riders from inner tubes to tubeless due to the numerous benefits of the system, which include:
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.
WIDE HOOKLESS BEAD AND MOLDED SPOKE HOLES
POT-HOLE AND IMPACT PROTECTION: Potholes and unforeseen impacts are part of the ride, but that doesn’t mean they need to ruin your day. The AR40 features ENVE’s 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.
MOLDED SPOKE HOLE: ENVE’s patented process of molding spoke and valve stem holes results in rims that are stronger and lighter. Because carbon fiber gets its strength from continuous fibers, ENVE routes the fibers around the hole without cutting them, increasing the strength of each spoke hole. This technique pays large dividends in the final product by allowing for a lighter spoke face while improving rim strength.
Because of this process, ENVE’s spoke holes are capable of maintaining higher spoke tensions, greatly reducing the risk of spoke pull-through and the need to constantly true your wheels. Strong, light, and maintenance free.
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.
The Foundation AR40 can be can purchased as a complete wheelset for $1400, or individually at $640 and $770 for the front and rear, respectively.
