ENVE AR40 Innerdrive Foundation Carbon Disc Brake Wheel

Description

Foundation for All Roads

The ENVE 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 29-30 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.

Molded Spoke Holes

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, the 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

ENVE’s INNERDRIVE Hubs represent 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.

Perfect Preload™ is a system that eliminates the need for bearing preload adjustments. Using a tuned wave washer, bearing preload is optimized from the factory and dynamically adjusted over the life of the hub. No tools required, just Perfect Preload all the time.
