Finally, a true MTB upgrade wheelset for high-end 24”! The SPOON 28-24 wheelset is a first of its kind wheel upgrade made specifically to service the 24” MTB market. Like its big brother the SPOON 32, the SPOON 28-24 wheelset is constructed with durable six series alloy and features SPANK’s patented OohBah™ rim profile, meaning the SPOON 28-24 is not only strong and stiff, but also safe and reliable. A 23mm internal width accepts a wide range of 24” tires from street to DH. Equipped with hybrid SPIKE Hubs with alloy freehub and internals to minimize weight, the SPOON 28-24 wheelset adapts easily to most major MTB standards.
The unique OohBah™ profile allows us 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.
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 is characterized by its inverted tube well. 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 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.
Another secret of SPANK’s patented OohBah™ profile, is our 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. 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!
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”.
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 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 confidence, comfort and safety.
