SPP CROWN JEWEL SUPERSIZED™ UHM HIGH MODULUS CARBON FIBER DISC SPECIFIC RIMS – Expert (451/ 520mm)

The SPP Supersized™ UHM Carbon Expert Rims bring the same crown-level engineering and performance philosophy to smaller and lighter race platforms. Utilizing the identical Supersized™ spoke interface, these rims reinforce the highest load zones at the spoke nipple while reducing material in low-stress areas. This results in a lightweight yet structurally optimized rim tailored for expert-level riders. Constructed from high modulus carbon fiber and produced through a precision vacuum molding process, the expert rims deliver a responsive, controlled ride with improved acceleration and handling characteristics. With 28-hole drilling to match lighter rider systems and a full disc-specific design, these rims maintain the same performance DNA as the Pro series—scaled appropriately for expert race categories.
