Designed for people looking for performance, style and additional torsional stiffness in their wheel choice. Spinergy's Lite Extreme LX X-Laced is designed for maximum torsional stiffness and responsiveness. The hybrid radial/x-laced pattern produces "wind up" when pushing, transferring or using wheels locks while maintaining optimal lateral stiffness. Like the LX wheels, there is plenty of space between the spokes for great reach-through access underneath your chair. The hub and spoke pattern look fantastic and deliver what they promise.
