Spank Spike Vibrocore Rim

Vibrocore is a proprietary foam core injected into the rim's cavity. It acts as a vibration-damping agent that absorbs high-frequency trail chatter, which helps reduce hand fatigue and improves traction on rough, technical descents.

While it is engineered for the heavy-duty demands of downhill and enduro racing, it works perfectly fine on aggressive trail bikes. Just keep in mind that it is built for durability and impact resistance, so it will be heavier than a dedicated cross-country or lightweight trail rim.

The rim is tubeless-ready, but it is fully compatible with standard clincher tires and tubes. You have the flexibility to choose whichever setup you prefer.

Directional drilling angles the spoke holes to align better with the hub flanges. This reduces the stress on the spokes and nipples, leading to a stronger, more reliable wheel build that is less prone to spoke breakage.

Not in this case. The Spank Spike rim uses a unique single-wall profile reinforced by the Vibrocore foam, which provides the necessary structural rigidity and impact resistance without the weight penalty of a traditional double-wall design.

Yes, this rim is designed specifically for disc brakes. It does not have a machined sidewall for rim brakes, so it is only compatible with disc-equipped bikes.
