Radial Compliance, Lateral Stiffness, Traction and Rolling Performance The rim features a unique low profile and very wide internal/external width. This increases radial compliance while ensuring lateral stiffness is not affected negatively. The improved radial compliance provides exceptional traction and rolling performance over rougher terrain and reduces negative feedback from the trail to the rider. Ultimately this wheelset is performance and comfort enhanced. Reduces Harmful Vibration Effects Featuring the Vibrocore inner rim filling, this wheelset effectively reduces the effects of harmful trail vibration to the rider. This transfers much less vibration to the bikes suspension and the rider and also significantly increases the fatigue life of the rim. This performance is enhanced further thanks to the wide 30mm internal rim width, which is superbly versatile and can fit tyres, with the perfect profile from 2.0 - 2.6". Plus tyres can also be mounted and will perform exceptionally also. VibroCore VibroCore technology is injected into Spank VibroCore products and dramatically reduces vibrations that can lead to hand and arm numbness, fatigue and arm-pump. This additional technology also increases overall stiffness and fatigue life of the product. VibroCore is one of the biggest innovations in Rim technology as it increases the radial compliancy, lateral stiffness and torsional strength while also damping vibrations from the trail. Oohbah The unique OohBah profile allows Spank to manufacture thinner walled, wider profiled, lighter rims without sacrificing strength or rigidity. Wider rims mean stiffer wheels and more tire spread, leading to greater traction and improved comfort, and tire performance. The “wave” shape of the OohBah inner tube adds strength and support to the vertical rim flange walls and prevent buckling. Normal straight or curved tube wells must be much thicker, and by default heavier, to offer the same support. Bead Bite At an incredible range of pressures, Bead Bite is the solution to keeping your tires burp free and fixed in place. Bead Bite rim technology enhances tubeless use with tires of all types and with a greater range of air pressures. Bead Bite rims have 6 rows of tiny ridges that run along the vertical and horizontal faces of the bead seats. These tiny teeth create air seals between the rim and tire as the bead conforms to them under air pressure. They dramatically increase frictional forces on the tire bead, reducing the beads’ ability to move vertically or horizontally (thus improving tire stability and reducing burps). The bead literally becomes trapped between the vertical and horizontal ridges, even at very low air pressures. Even in tubed applications, Bead Bite rims tend to allow much lower air pressures with reduced risk of pinch flats.... More
