Killer Junk

Killer Junk 110mm – Firm • X-Firm • XX-Firm

Built for one mission: maximum free speed 🔥 The Killer Junk 110mm takes everything skaters love about the iconic Road Reaper and pushes it even further—stiffer hub, upgraded rebound, and a tuned inner-ring system that delivers insane roll with controlled edge grip.

Tested across thousands of laps, dozens of prototypes, and countless race-day battles, Killer Junk is engineered for skaters who want every watt of speed transferred straight to the ground. ⚡

🏆 Proven by the Fastest Skaters Alive

🎨 Natural Raw Urethane – Color Variation

Killer Junk uses raw, natural urethane with no pigments. Because of this, the appearance of the wheels can vary:

• Some wheels may look more milky or cloudy.
• Others may look more transparent, which can make the inner ring appear more visible or “redder.”

This is a natural feature of pigment-free race urethane — not a defect. Some of our set photos show this variation clearly and are a good example of how raw urethane can differ from wheel to wheel.

Killer Junk is a pure speed weapon — engineered for athletes who demand more roll, more stability, and more power out of every push. 🔥
