Spank 369 Spike Vibrocore Rear Wheel

The Vibrocore foam is engineered to dampen high-frequency trail chatter before it reaches your hands and feet. By absorbing these vibrations, it reduces rider fatigue on long descents and helps the wheel track more predictably over rough terrain.

This is a 29-inch wheel with a 6-bolt brake mount. You should verify that your frame uses a standard thru-axle spacing compatible with the hub provided and that your bike is designed for 29-inch wheels.

The Bead Bite hooks are designed to mechanically lock the tire bead in place, which significantly improves tubeless security at lower pressures. While this makes the tire seal very reliably, it can make the initial installation or removal slightly tighter than on standard rims.

Yes, the 3.5-degree engagement provides nearly instant power transfer when you pedal. This is particularly useful in technical sections where you need to ratchet your pedals to clear obstacles without waiting for the hub to engage.

The 30.5mm internal width is an ideal sweet spot for modern trail and enduro tires, typically supporting widths between 2.3 and 2.6 inches. This width provides a stable, square profile for the tire, which helps prevent sidewall squirm during hard cornering.

The hollow bead wall design increases the rim's vertical compliance and impact resistance. By allowing the rim to absorb more energy during hard impacts, it reduces the likelihood of the tire casing being pinched against the rim edge, which is the primary cause of pinch flats.
