• Momentum is a dual compound that balances grip with rolling efficiency and tread life. The center lugs use a firmer 50a durometer for faster rolling and better durability, while the shoulder lugs use the same 42a MoPo rubber to keep cornering confidence high. MoPo up front, Momentum in the rear is a proven combo for riders who want grip where it counts and speed where it helps.
• MoPo is a pure 42a single compound designed for maximum grip. The soft durometer and slow rebound give you the highest possible traction in corners, under braking, and through loose terrain. It's the go-to choice for front tires and gravity riding where grip matters more than anything.
