The Spinergy 507mm wheel is specifically designed for use with a mountain bike style tire (Kenda Booster Pro), or large volume road style tire. We’re tapping into the bicycle market to be able to offer this size - 507mm is typical wheel size for kids bikes and BMX bikes. We use our thick 4mm spokes and our SLX Sport hub to enhance the durability of the wheel for peace of mind in rough terrain.

WHAT'S INSIDE OUR SPOKES?

PBO FIBER

poly(p-phenylene-2,6-benzobisoxazole)

THE STRONGEST SYNTHETIC FIBER ON THE MARKET

3X STRONGER THAN STEEL, 1/2 THE WEIGHT

Using PBO Fiber for spokes on a wheelchair wheel offers numerous advantages over traditional metal spokes. PBO Fiber is exceptionally lightweight and durable, reducing overall wheelchair weight and enhancing maneuverability while maintaining strength and resilience. PBO Fiber spokes absorb vibrations, providing a smoother ride and minimizing discomfort for the user. Additionally, its corrosion-resistant properties make it ideal for long-term use in various environmental conditions, contributing to a more reliable and maintenance-free wheelchair experience.

EACH SPOKE HAS 44,000 INDIVIDUAL PBO FIBERS!
