These rims feature the unique Oohbah technology, found only on Spank rims and wheels. Traditionally, the central channel of a rim is slightly curved or flat on most rims, but the Spank specific Oohbah design features a wave-like pattern in the centre. This Oohbah feature in the centre of the rim adds exceptional strength and makes the entire rigid and creates greater lateral stiffness, traits commonly only found on wheels that are much heavier. This structural benefit also allows Spank to make rims that are wider without having to add extra material, which would in-turn make them heavier.
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 into 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.
