Killer Junk 110mm XX-Firm Speed Skating Wheels

Killer Junk 110mm XX-Firm – Natural Hub Edition 💀🔥

We’ve got Killer JUNK – built for skaters who live in the red zone of speed. If you know Junk, you know we’re on a tireless pursuit of ultimate speed: we engineer an idea, test it, tweak it, and push it until it’s faster than anything that came before.

Killer Junk was born from a wheel you already know – the one that reaped countless medals and turned skaters into world champions: Road Reaper. The difference? A stiffer natural hub, refined MTech® geometry, and a few top-secret tweaks under the hood that make this wheel feel absolutely lethal on the track and road.

🏆 Proven by World Champions & Record Performances

Killer Junk belongs to the same Junk performance family trusted by the world’s fastest skaters:

• Sebastián “Chevi” Guzmán used Junk wheels to break the 100m and 200m World Records at the 2025 World Games, on his way to winning more Gold Medals at a single World Games than any athlete in history (100m, 200m, 500m, 1000m Track, and 1-Lap Road), plus the 100m and 500m Sprint at the 2025 World Championships.
• Junk founder Francisco Ramirez skated a 24-hour track distance record of 380.8 miles on Junk wheels – proving that our designs can go from explosive sprint efforts to full-day endurance without breaking down.

From world-record sprinters to ultra-distance grinders, Junk wheels are trusted when the stakes are highest and there are no second chances.

⚡ Killer Feel: Rolls Hard, Grips Smart

Killer Junk XX-Firm (86–88A) has been extensively tested by top sprinters and endurance skaters:

• 💨 Sprinters love the way it rolls like a harder wheel – perfect for the second half of the 1000m when the legs are screaming but the speed has to keep rising.
• 🧠 Endurance and marathon skaters love how it grips like a softer wheel, keeping control through corners and packs while still delivering insane roll on the straightaways.
• 🏁 Ideal for track points, elimination races, and fast marathons where any wasted watt is a lost position.

The XX-Firm version is your choice when conditions are hot, grippy, and fast, and you want maximum roll without feeling sketchy under pressure.

🌱 Natural Hub, Raw Urethane – Pure Performance

Killer Junk features a natural hub with no pigments. In testing, our natural hubs consistently outperform colored hubs with:

• Better roll
• More consistent grip
• Improved wear resistance

As with all Junk wheels, the urethane is in its raw Magic Urethane form – no additives, no pigments, just pure performance chemistry tuned for speed.
