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.
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.
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
