ENVE Composites AG28 Foundation Rim

The AG28 is built for gravel and mixed-surface riding where comfort and durability are priorities. Its 21mm shallow profile is specifically tuned to provide vertical compliance, which helps absorb chatter and vibration on rough terrain.

While the rim is optimized for tubeless setups, it is technically compatible with tubes. However, the wide hookless bead design is engineered to perform best with tubeless tires, which allow you to run lower pressures to maximize traction and pinch-flat resistance.

The 28mm internal width is quite wide, making it ideal for high-volume gravel tires. You will get the best stability and tire profile when pairing these with tires ranging from 40mm to 55mm wide.

No, the AG28 Foundation rims are designed exclusively for disc brake setups. They do not have a braking surface on the sidewall.

Because this is a hookless rim, you must use tubeless-ready tires that are specifically approved for hookless compatibility. Always check your tire manufacturer's specifications to ensure they are rated for hookless rims and adhere to the maximum pressure limits.

The 650b diameter is smaller than the standard 700c road wheel, offering increased maneuverability and clearance for wider tires. Ensure your bike frame and fork have the necessary clearance for 650b wheels before purchasing.
