Killer Junk Firm 110mm Inline Speed Wheels

Killer Junk 110mm Firm – Natural Hub

We’ve got new killer JUNK. ⚡
If you know Junk, you know we’re on a tireless pursuit of ultimate speed. We engineer an idea, test it, tweak it, and obsess over every detail to squeeze out that extra bit of performance with every new product.

Killer Junk was born from a wheel you already know – the legendary Road Reaper that has “reaped” countless medals and turned skaters into world champions. The difference? A stiffer hub, a natural (pigment-free) core, and a few top-secret tweaks under the hood that give this wheel its own vicious personality on the track and road.

🏆 Connected to World-Record & Ultra-Distance Performance

Killer Junk comes from the same Junk engineering that has rewritten modern speed skating:

• Sebastián “Chevi” Guzmán used Junk Road Reaper wheels to break the 100m & 200m World Records and to win more Gold Medals at the 2025 World Games than any skater in the event’s history.
• Chevi also won the 100m & 500m sprint at the 2025 World Championships on Junk wheels.
• Junk’s founder Francisco Ramirez rolled an incredible 380.8 miles in 24 hours on a track, setting a brutal 24-hour track distance record and proving how efficient Junk wheels are over ultra-endurance efforts.

Killer Junk is built from the same DNA – designed for skaters who attack every lap, every move, every race.

⚡ Built for Sprinters & Endurance Killers

Killer Junk wheels have been extensively tested by our top sprinters and endurance skaters:

• They roll like a harder wheel for insane top-end speed.
• They grip like a softer wheel so you can commit to every corner.
• Long-distance skaters love the extra roll for points and elimination races, while sprinters feel the difference in the second half of the 1,000m when the legs start to burn.

🌱 Natural Hub, Natural Urethane – Pure Performance

The natural hub contains no pigments, and our testing has shown it simply performs better:

• Better roll
• More consistent grip
• Improved wear resistance

As with all our wheels, the urethane is also in its raw form – no additives or pigments – just our Natural Magic Urethane tuned for maximum speed and feel.
