Spank SPIKE Race 33 Mountain Bike Disc RimA versatile rim that's ready to rumble on the downhill and ramp up the speed as you race to the finish line, the SPIKE Race 33 MTB Rim ticks all the boxes when it comes to functionality and trickability. Lightweight and tubeless ready, control and confidence are key to this adaptable effort from Spank Industries.Durable and Versatile Hard-Riding Rim This impressive rim, built from a top-performance alloy that keeps the weight low and strength high, is the ideal option for freeride, race and downhill riders looking for a reliable and hard-wearing wheel build. Coming tubeless ready, your tyre inflation can be set lower to improve grip when cornering and breaking on your choice of terrains, while the anti-burp rim hooks prevent any unnecessary air-loss for maximum efficiency at all times. Equipped with 32 spoke holes, a corrugated rim centre that enhances the rigidity and strength of the rim itself while keeping a low weight and a shot-peen finish which helps to relieve stress on the metalwork, the SPIKE Race 33 MTB Rim is prepared to be pushed to the limits. Features: Material: Top-Performance Alloy Rim Size: 29" Inner Width: 28mm Outer Width: 33mm Hole Count: 32 Valve: F/V Presta Tubeless: Tubeless Ready Technologies: BeadBite Anti-burp, OohBah Inverted Inner Wall Weight: 525g (approx) Technologies: 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 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. 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.
