BMX legend Toby Henderson brings his design experience to a completely new generation of carbon forks for SPP. Starting with a proven race‑geometry, he re‑imagined every detail around Supersized Technology – larger cross‑sections and muscular shoulders that shift carbon to the places that take the biggest hits, improving stiffness and tyre clearance. Each fork is crafted from high‑modulus unidirectional carbon fibre legs mated to a cost‑efficient 7075‑T6 alloy steerer. The result is a fully integrated crown and steerer that delivers laser‑sharp steering and reduced deflection. To handle the demands of modern BMX racing, 10/15 mm thru‑axle dropouts are cold‑forged from aluminium for maximum durability, while an internal butterfly reinforcement strengthens the steerer‑crown interface.2 models cover 20″ and 24″ wheel sizes with 1” to 1 1/8”  tapered alloy steerers, giving riders durability and price point. Each fork is finished in a gloss carbon lay‑up with molded SPP graphics and includes a headset wedge for easy headset adjustment. Whether you’re chasing an expert podium or building a high‑end cruiser, SPP’s Supersized expert forks provide pro‑level precision, strength and style.

Supersized Technology
Enlarged crown and leg cross‑sections shift carbon from low‑stress areas to high‑load zones, delivering superior steering stiffness and precision.

Alloy steerer
7075‑T6 aluminium steerer for a strong and lightweight combination
20 mm thru‑axle dropouts
Cold‑forged aluminium dropouts accept 10/15 mm axles for heightened responsiveness and stability.

Internal butterfly reinforcement
A hidden butterfly insert at the steerer‑crown interface improves durability and distributes loads, reducing the chance of steerer failure.

High‑modulus carbon legs
Vacuum‑moulded unidirectional carbon fibre legs provide race‑level stiffness while keeping weight to around 560g for 20″ models.

Headset Wedge hardware included
Wedge system replaces the traditional star‑nut, keeping the steerer intact and allowing for precise headset adjustments.

Proven race geometry
32 mm fork offset and 303 mm axle‑to‑crown height preserve the handling that top racers expect
