• Low drag and an improved transition between rim and tire, boosting aerodynamic efficiency with wider tires.
• Wide-rim stance also features less tire deflection for reduced rolling resistance.
• The wider tire, increased tire volume, and lower tire pressure helps reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions

• Refined rim shape helps shield the tire in an impact that would otherwise cause a pinch flat.
