Key Features & Performance

Ultra Low Inverted Kingpin
Designed with a recessed, ultra-low kingpin that sits deep inside the truck, eliminating contact during grinds. This delivers smoother lock-ins and completely removes the risk of hang-ups.

Hollow Kingpin & Axle Construction
Both the kingpin and axle are hollowed out to reduce weight without sacrificing strength, giving you better flick, control, and overall board feel.

Maximum Grind Clearance
Widely known as the benchmark for grind clearance, this design increases your grind angle and keeps slides smooth and consistent across all surfaces.

Forged Baseplate
A forged baseplate provides enhanced durability while remaining lightweight, ensuring long-lasting performance under heavy skating.

Fast, Responsive Turning
Built for immediate responsiveness with no break-in time, delivering quick, precise turns straight out the box.

Reduced Wheel Bite
Optimized geometry and bushing setup help minimise wheel bite, allowing you to ride looser trucks with confidence.
