. This performance enhancing wheelset offers a massive power boost for any aggressive downhill rider looking for a stability advantage. The alloy rim on each wheel features a corrugated rim centre for increasing strength and rigidity, giving you remarkable control even on the toughest descent. Each rim features a massive 33mm outer width, allowing you to run wider tyres for increased uphill traction and smooth rolling even on the toughest surface Boost Enhanced Spike Hubset. This wheelset has been fine tuned to give its rider DH World Cup level performance, which includes pairing each wheel with a boost sized hub for increased stability. The 3 cross spoke configuration increases overall wheel durability, perfect for handling the impacts of downhill racing. Plus, anti burp rim hooks have been installed to prevent pressure loss and hold your tyres firmly for a streamlined, secure performance Features RimAlloy Clincher Tubeless Ready Rim Width28mm inner, 33mm outer SpokesJ Hook, triple butted, 32H, 3 Cross Lacing NipplesAlloy DSN Hubset Spike with Boost spacing on rear Weight2.0kg 2 08kg 27 5", 2.04kg 2 15kg 29"Technology OohBahThe 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. BeadBiteAt an incredible range of pressures, BeadBite is the solution to keeping your tires burp free and fixed in place. BeadBite rim technology enhances tubeless use with tires of all types and with a greater range of air pressures. BeadBite 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, BeadBite rims tend to allow much lower air pressures with reduced risk of pinch flats BuySpank Wheels & Tyresfrom Chain Reaction Cycles, the Worlds Largest Online Bike Store.
