Moderately low 19mm profile height and wide width, balances the benefits of radial compliance with high lateral stiffness and predictable handling
Radial Compliance improves traction over bumps and chatter, while reducing negative feedback to the rider. Performance and comfort are improved
5mm inner width is extremely versatile, fitting tires from 2.0” to 2.6”, and even allowing + size tire use without negative squaring off of tire profiles
Bead Bite tubeless hooks enhance tubeless performance and tire security, even at lower pressures
