Spank Spike Race33 Boost E-XD Rear Wheel 29 Inch 32-Hole 148mm - black

The Spike Race 33 wheels were specifically developed to offer Enduro, Freeride, and Downhill riders very lightweight, robust, and high-quality wheels. In this case, Spank has combined the Spike Race 33 rim with an e-bike specific Spank Hex J-Type hub made of steel.

The 29-inch, 32-hole rim is only 28 mm wide, somewhat unusual compared to other hardcore rims, but this gives the tire a smaller contact area, resulting in significantly lower rolling resistance. Thanks to the special OohBah rim construction, occurring force flows are better dissipated, making the rim extremely stable and resilient. Additionally, this construction allows for weight optimization.

E-mountain bikes are no longer just a trend in Germany and Austria, but have become an integral part of the sport. Therefore, it is even more important to have specifically adapted parts that are designed for use with an e-motor and its power influences. Thus, the HEX hubs are now also available with freewheels made of steel.

Technologies of the Spank Race 33 wheels:

OohBah™
The term OohBah describes Spank's exclusive rim profile, which, through special construction, better dissipates occurring force flows and thus prevents dents. Furthermore, the wall can be adjusted at various points to construct the rim lighter without losing stability.

BeadBite
BeadBite creates an improved seal between the rim bed and tire bead, so no air can escape, no matter how much the tire moves. It also ensures that the tire bead is firmly anchored to the rim bed and cannot slip.
