Wide Hookless Bead Flat Protection Goodbye to pinch flats: 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. 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 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 Nipples Reliability 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. Enve Foundation Road Hub Utilizing ENVE's core hub technologies the Foundation Road Hub delivers a high performance, maintenance-free ride experience. - Flange spacing and hub shell geometry designed to maximize performance metrics such as wheel and drive stiffness - ID360 40t drive mechanism delivers efficient and responsive power transmission - Maintenance free premium full contact sealed NTN steel bearings - Perfect Preload USA Made, Protected for Life It's no secret that we at ENVE are proud of our U.S. based manufacturing capabilities.
