Spank Oozy 26AL EVO Rim

Our unique patented Oohbah profile with inverted tube well increases rigidity immensely compared with rims currently available. Additionally the Oohbah allows us to optimize the design and drastically reduce weight to offer the toughest performance hoops in their price to weight ranges.

The sectional profile is super rigid while the BeadNip ensures that the tire remains in the beadseat even while riding at minimal tire pressure the nip also reduced snake bites.

    “Dynamal” is a new, rare, virgin alloy composition. 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. Imported and rare in our industry, Dynamal is used in the production of Spank’s VOMAX, OOZY, Subrosa, and SPIKE rim lines. It offers unparalleled rigidity in rims and a never before seen resistance to permanent deformation.
  • OOHBAH: The most important features of any rim are rigidity and weight. Rigidity or stiffness means more of your energy is transferred into drive force, (rather than flex) and acceleration/cornering/braking performance is improved. Reducing rolling weight in your wheels, more so than any other part on your bike, can dramatically reduce the energy needed to propel it forward. Take a look at a cross section of any given rim on the market. You’ll see that both the outer and inner walls are concave. Now check out a SPANK rim. Our unique patented Oohbah™profile with inverted tube well, approaches a toroidal shape, which has the lowest mass and highest stiffness on all planes. This increases rigidity immensely compared with conventional rim designs. The combination of a concave outer wall with a convex inner tube well, results in the addition of a new, never before seen “hoop strength” in the sectional profile, which lends massive strength and stiffness to the rim as a whole, and places the center of inertia in the optimum position nearer the center of the profile. Furthermore the “wave” shape of the Oohbah inner tube well acts like corrugated steel roofing to add strength and support to the vertical rim flange walls and prevent buckling. Normal straight or curved tube wells must be much thicker to offer the same support. The increased strength and rigidity offered by our Oohbah™profile affords us the opportunity to optimize wall thicknesses and material transitions, drastically reducing weight…AND…allows us to offer rims with greater widths, at much lower weights than our competitors. Wider rims mean stiffer wheels and more tire spread, leading to greater traction and improved comfort.
  • BEADNIP: Another secret of SPANK’s patented Oobah profile, is our double Beadnip™technology. Traditional rim designs include only one set, called bead hooks on the vertical walls or rim flanges. The vertical hooks are crucial for tire retention. The Oohbah patent includes the addition of a second set of “nips” on the inner tube well (horizontal inner wall), which ensure the tire always remains in the bead-seat, even when riding at minimal tire pressures. Without it, on conventional rim designs the bead can slip inwards, leading to snake bites (pinch flats). Interestingly, in tubeless applications, the beadnips also act to trap the bead, preserving the seal between tire and rim, enhancing air pressure longevity and reducing annoying “burps”. With SPANK’s Oohbah patented rims, you can ride the tires you want, at the pressure you want, on any terrain…with far less fear of flats!
  • MGR: Micro Grain Refinement- 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 the grain size beyond that of our competitors. No other bars are subjected to the number of drawing steps or level of refinement as those offered by Spank. This leads to greater ultimate strength, toughtness, and ductility...meaning confidence, comfort and safety.
