The SPP Supersized™ Alloy Pro Rims bring race-proven performance to aluminum through a refined low-profile design, premium materials, and advanced construction methods.

Manufactured from 6061-T6 aluminum, these rims utilize a sleeved joint construction—delivering improved structural integrity and consistency compared to traditional pinned designs. Stainless steel eyelets reinforce each spoke interface, distributing load more evenly and increasing durability under sprint and landing forces.

The organic rounded profile improves impact distribution while maintaining a responsive ride feel. Combined with a Supersized™ interface philosophy, the rim is engineered to maximize strength where it matters most without unnecessary weight.

Tubeless-ready and disc-specific, these rims are built for modern BMX race applications where reliability, stiffness, and clean system integration are critical.
