This Spank Oozy Trail 295 Bead-Bite MTB Rim is no longer available although you may find similar or newer versions below:
The Oozy Trail 295 is the rim of choice for Spank's Downhill World Cup Race Team and Big Mountain Freeriders. Being light and resilient, it is innovative, versatile, and race-ready.
Packed with high-end tech and super strong, the Oozy Trail MTB rim is pro-proven and ready for a custom build.
The Oozy Trail 295 MTB Rim is made from an advanced alloy and Spank's innovative, bespoke manufacturing process ensures that each alloy MTB rim is incredibly light and strong to withstand the most aggressive and technical trails.
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.
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.
Another secret of SPANK’s patented OohBah profile, is the double BeadNip technology. The OohBah patent includes the addition of a second set of “nips” on the inner tube well which ensures that the tire always remains in the bead-seat, even when riding at minimal air pressures. Traditional rim designs include only one set of bead hooks on the vertical walls or rim flanges. The vertical hooks are crucial for tire retention. Without the bead hooks, the bead can slip inwards, leading to snake bites (pinch flats). In tubeless applications, BeadNip also acts to trap the bead, preserving the seal between tire and rim, enhancing air pressure longevity and reducing annoying “burps”.
Dynamal Alloy is the safe, affordable and responsible alternative to carbon fibre. Utilising the endless lifecycle of aluminium, Spank's proprietary alloy blends offer superior mechanical properties resulting in stronger rims and reduced weight through optimised design. Spank Industries has made a concerted effort to develop safe and affordable alternatives to the excessive use of carbon fibre in the bicycle manufacturing industry. Spank's WC DH Race Teams and their most hard core Big Mountain Freeriders are running Spank’s Dynamal Alloy rims in the choice against carbon fibre. Unlike standard recycled alloy mixes, Dynamal is a dynamically aged highly magnesium-silicon enriched, pure alloy, which is blended with a special "secret" hardening metal. Compared to statically aged traditional alloy types, Dynamal shows a significant further increase in ultimate tensile strength and yield, without the normal reductions in fatigue life.
Processes such as extrusion, forging and tube drawing can increase the strength of alloy materials by reducing the grain size. SPANK uses state of the art proprietary metal forming methods which further improve grain size consistency and orientation, and significantly reduce grain size beyond that of our competitors. No other bars or rims are subjected to the number of drawing steps or level of refinement as those offered by SPANK. This leads to greater ultimate strength, toughness, and ductility, meaning greater rider confidence, comfort and safety is achieved.
Spank was created out of the passion for a sport that has more style than any other. This style fashion and design enables valuable products to be created which riders from around the world stand for. These individuals embody Spank through their lifestyle. Spank trust their knowhow and bring to this their own experience in manufacturing.
