Enve Foundation AR40 White 2026

ENVE Foundation AR40 White 40mm carbon road wheels with tubeless disc brakes, 2026

The ENVE Foundation AR40 wheelset is designed to offer maximum versatility to road and all-road cyclists seeking performance, efficiency, and reliability on all terrains. The latest addition to the Foundation range, the AR40 combines a modern 40mm aerodynamic profile with a generous 25mm internal width to optimize both road speed and off-road comfort and control.

Developed for fast rides on asphalt, long gravel adventures, and demanding courses, this carbon wheelset benefits from ENVE's aerodynamic expertise gained from over 15 years of developing high-performance wheels. Tested in the Mercedes-Benz Formula One wind tunnel, it guarantees real-world efficiency in actual riding conditions and at various speeds.

Compatible exclusively with tubeless tires, the Foundation AR40 improves performance, significantly reduces the risk of punctures, and allows for more precise pressure adjustment to maximize comfort, grip, and efficiency. Its wide hookless design, molded spoke holes, and ENVE INNERDRIVE™ hubs ensure long-term strength, reliability, and low maintenance.

Aerodynamic

Wind tunnel development

Tested and developed in the Mercedes-Benz Formula One Wind Tunnel.

ENVE Approach

Development and validation of wheels mounted on bicycles, at real speeds between 32 km/h and 48 km/h, for concrete aerodynamic performance on the road.

Objective

Improve efficiency, stability and control regardless of wind conditions.

Tubeless technology

Main advantages

Reduced rolling resistance, fewer punctures and optimized rolling pressure.

Hookless profile

The hookless/straight-sidewall design ensures precise tolerance at the tire seat to improve tubeless performance.

Performance

Provides greater comfort, more traction and better overall performance.

Protection and durability

Wide Hookless Bead

Patented ENVE technology dissipates impact energy and reduces the risk of pinch flats and punctures on major impacts.

Molded Spoke Holes

The spoke and valve holes are molded and not drilled, allowing the continuity of the carbon fibers to be maintained for a lighter and stronger rim.

Benefits

Increased strength, better spoke tension retention, reduced risk of pull-out and very low need for truing.

ENVE INNERDRIVE™ Hubs

Ratchet system

Oversized 42mm ratchet system entirely designed by ENVE.

Functioning

Oversized steel pawls are positioned above the bearings to reduce stress on the shaft and improve engagement.

Benefits

Extended bearing life, reduced friction, automatic preload, low maintenance and simplified upkeep.
