- 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.
- Vibrocore™ inner well, reduces the transmission of harmful vibration frequencies, meaning less vibration for the suspension and rider, also increasing the fatigue life of the rim
- 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
- RECOMMENDED FOR: ASTM 5, All mountain, Trail, enduro, free ride, DH, E-Bike
- RIDER TYPE: HEAVY TO LIGHT RIDER: Heavy to Light Impact
