ENVE Foundation AR40

The AR40 is the latest addition to the Foundation lineup. Featuring an aerodynamically optimized 40 mm 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 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. The wide range of capabilities make the AR40 a perfect upgrade to any modern road bike, all-road bike, or gravel racing bike.
