A Unique profile with low sectional profile height and wide width, which adds radial compliance, while keeping high lateral stiffness. Improved radial compliance for better traction over bumps and chatter, while reducing negative feedback to the rider. Performance and comfort enhanced. 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. 30mm internal width is extremely versatile, fitting tires from 2.0 to 2.6 perfectly, and even allowing + size tire use, without negative squaring off of tire profiles. Ideal for DH and Freeride.
