Spank 350 Boost XD Rear Wheel

This rear MTB wheel offers power, stability and dependable performance, so off-road riders can pedal up and down the mountain with confidence and style. This high-level rear wheel is strong, tubeless-ready and suited to enduro racing. Reliably built for taking on the most exhilarating runs, this rear-wheel comes fitted with a 12x148mm Boost hub which lets you fit plus-sized tyres for the boldest ride possible.

Coming tubeless-ready to keep Trail, All Mountain and Enduro riders at their peak, the Spank OOZY 350 Boost XD Rear Wheel is optimised for rough and ready riding. Constructed using a wide rim profile to take on larger tyres and keeps a strong and sturdy form thanks to 28 straight pull, triple-butted spokes.

Made with a variety of technologies to keep you rolling through the harshest conditions, this wheel makes the most of its radial compliant and laterally stiff rims. Plus, its rim features an innovative OohBah inverted wall and a BeadBite Anti-burp rim-hook set-up to maintain the shape and structure of the wheels and air pressure in your tyres.

  • 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 tyres 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 tyre as the bead conforms into them under air pressure. They dramatically increase frictional forces on the tyre 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.
  • 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.
