Spinergy 72920 Lightweight Manual Wheelchair Wheel with PBO Fiber Spokes

The Spinergy 72920 is a high-performance manual wheelchair wheel built around Spinergy's proven engineering philosophy: maximum strength with minimum weight. Designed for active wheelchair users, this wheel combines a precision-machined aluminum hub with Spinergy's patented PBO (Polyphenylene Benzobisoxazole) fiber spoke technology to deliver a ride that outperforms traditional steel-spoked wheels in every measurable way.

Key Features:

• Patented PBO fiber spokes — 3x stronger than stainless steel at half the weight, providing outstanding durability with reduced rotational mass
• Superior vibration damping — PBO fiber spokes absorb approximately 25% more shock and vibration than steel spokes, reducing fatigue and improving comfort over varied terrain
• Lightweight aluminum double-walled rim — CNC machined for precise tolerances and long-term structural integrity
• Corrosion-resistant construction — engineered to withstand daily use, moisture, and impact without degradation
• Compatible with standard wheelchair tires — accepts a wide range of tire widths used in wheelchair applications
• Rivnut handrim mounting system compatible — works with most standard handrim configurations

Spinergy wheelchair wheels are a trusted upgrade for manual wheelchair users who demand reliability and performance in daily life or active pursuits. The 72920 reflects Spinergy's commitment to combining advanced materials science with practical, user-focused design.
