SPANK RACE 33 RIMS The Spike Race 33 is a super-strong, light and stunning high-end gravity enduro / freeride / downhill rim featuring the innovative OohBah profile and Bead Bite technology, made of the exclusive Dynamal Alloy aluminium. The extra-wide profile provides a proper platform for wide tires to play out all their advantages. 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. Technologies of the Spank Spike Race 33 Oohbah - Spank's unique patented Oohbah profile with inverted tube well increases rigidity immensely compared to other rims currently available. Additionally Oohbah allows to optimize the design and drastically reduce weight to offer the toughest performance hoops in their price to weight ratio. BeadBite - BeadBite creates more contact between sealing rim and tire bead, so that no air can escape, no matter how much the tire moves. It also ensures that the tire is firmly anchored to the sealing rim and do not slip anymore. Dynamal - Dynamal is a dynamically aged, complex and highly magnesium-silicon-copper enriched alloy. Compared to conventional alloy types, it shows significantly increased tensile strength and yield, without compromising fatigue life. Dynamal offers unmatched rigidity and resistance to permanent deformation.
