WIDE HOOKLESS BEAD FLAT PROTECTION
The cringe-inducing impact between rock and rim is something we’ve all experienced when the desire to shred trail overwhelms our better judgement. Unless you’re running too much tire pressure, that impact will typically result in a pinch flatted tire.
The AG25 and AG28 feature our patent pending wide hookless bead technology which has proven to shrug off pinch flats to the tune of a 60% improvement over a traditionally more narrow hookless bead.
GRAVEL RIDE TUNE
By using on board data acquisition equipment and aligning it with subjective test ride feedback, our laminate design team have refined the AG25 & AG28 to deliver a ride quality that is both responsive and compliant, supportive yet forgiving.
- Shallow rim depth of 21mm allows improves vertical compliance and vibration damping
- Rim cross-section and laminate optimized for responsive power transmission and cornering stability
BUILT TO SHRUG OFF YOUR BAD IDEAS
So, you’ve decided to descend that mountain bike trail on your gravel rig. Or maybe you didn’t have a choice, it was the only way to get from point A to point B. No worries, we encourage it. Which is why we’ve designed and tested the Foundation AG wheels using our proven M Series impact testing protocol. The result is a wheel that inspires confidence when you need it the most, even when you aren’t looking for it.
EXTERNAL MOLDED NIPPLESRELIABILITY FIRST, SERVICEABILITY ALSO FIRST
By employing ENVE’s patented molded spoke hole technology and configuring it for external nipples, you can rest assured that you’re riding a wheel that’s been built for reliability and serviceability when you need it most.
USA MADE, PROTECTED FOR LIFE
It’s no secret that we at ENVE are proud of our U.S. based manufacturing capabilities. Like all our rims, the Foundation Collection and its AG25 are handmade and assembled in our Ogden, Utah based, state-of-the-art carbon wheel manufacturing facility.
The AG25 is covered under ENVE’s Lifetime Incident Protection program and 5 Year Factory Warranty.
