ENVE AR40 Wheels

The AR40 is the latest addition to the Foundation lineup. Featuring an aerodynamically optimized 40 mm rim depth front and rear, with a 25 mm 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 SES rim design knowledge, the AR40 is aerodynamically tuned for 29 mm – 30 mm tires and delivers drag reduction that punches 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.
