Spank Industries - Spike Race33 26"/27.5" Rim (Bicycle)

The Spank Industries Spike Race33 rims are the pinnacle of bike rims. Now you can add traction and stability to your ride without sacrificing speed. SPANK Industries is a longtime leader in the development of wide rim technology. The Spank Spike Race 33 Mountain Bike Rim is the evolution of Spank’s infamous Spike Race rim line up. With a 28mm inner profile, the SPIKE Race 33 combines the wide stance of its predecessor the SPIKE 35 EVO, with the light weight of Spank’s legendary Race 28. The Race 33 was designed to optimize tire spread across a wider array of tires options, without squaring off tire profiles, making it ideal for anyone in need of enhanced traction and stability without compromising speed on track.

Sturdy Dynamal alloy construction paired with SPANK’s acclaimed OohBah™ rim design, make the Spike Race 33 one of the strongest alloy hoops on the market. Equipped with SPANK’s patented Bead Bite™ anti-burp tubeless system, the SPIKE Race 33 offers unmatched tire security and performance with or without tubes. With Spank's best mountain bike wheel tehcnology put into the Race33, you will never have to worry about rim failures ever again. 

Dynamal Alloy:

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 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.

Oohbah Reverse Well Design:

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.

BeadBite:

Are you 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.
