Description :

The World’s top Street Trials riders have spoken! SPANK Industries has always pioneered alloy rim profile development, and the SPIKE Race 33-24 marks a game changer for 24” MTB. The rim of choice for street trials riders such as Danny MacAskill and Fabio Wibner, the Spike Race 33-24 combines a wide inner profile, the performance and rigidity of SPANK’s Oohbah rim profile, and the ultimate strength of Dynamal alloy, with the industry leading tubeless security of Bead Bite anti-burp tubeless rim hooks. Looking for the ultimate upgrade to your 24”? Look no further!

The technology behind this product

Beadbite™

Enhanced anti-burp and tire retention tubeless performance.

Running tubeless? No stress! At an incredible range of pressures, Bead Bite™ is the solution to keeping those tires burp free and fixed in place. Bead Bite™ rim technology, paired with SPANK‘s patented OohBah™ profiles, 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 bead‘s 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™

Inverted tube well design for greater cross sectional strength - wider, lighter rims.

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.

BEADNIP™

Improved tire fit.

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”.

Dynamal Alloy

Safe, affordable and responsible alternative to carbon fiber.

Utilising the endless lifecycle of aluminion, our proprietary alloy blends offer superior mechanical properties resulting in stronger rims and reduced weight through optimized design. SPANK Industries has made a concerted effort to develop safe and affordable alternatives to the excessive use of carbon fiber in the bicycle manufacturing industry. Our WC DH Race Teams and our most hard core Big Mountain Freeriders are running SPANK’s Dynamal Alloy rims in the choice against carbon fiber. 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.

MGR

Micro grain refinement processed alloys.

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.
