- Unique profile with low sectional height & wide width adds radial compliance & lateral stiffness
- Improved radial compliance for better traction over bumps & chatter while reducing negative feedback to the rider gives enhanced performance & comfort
- Vibrocore™ inner well reduces the transmission of harmful vibration frequencies & increases the fatigue life of the rim
- 30mm internal width is versatile fitting tires from 2” to 2.6” and allows plus size tire use without negative squaring off of tire profiles
