WedsSport first introduced the "H-Cross" spoke side milling concept in 2010. This innovative approach was developed and rigorously tested to address the challenge of increasing spoke strength, particularly on larger diameter wheels where flex tends to be more pronounced due to the longer spoke length. Traditionally, the solution to this issue involved adding more material to the spokes, but this invariably resulted in added weight.
Drawing on principles of structural physics and thorough material composition studies, WedsSport engineers embarked on a quest to find the optimal spoke cross-section shape for enhanced strength. This pursuit culminated in the development of the "H-cross" spoke design. Notably, the distinctive H-section cannot be achieved by die molding alone; it necessitates additional machining to be realized. The incorporation of radii in this design serves to increase surface area, thereby enhancing both strength and rigidity.
This innovative concept paved the way for the creation of lightweight sports wheels that seamlessly integrate exceptional design with significant weight reduction. WedsSport initially implemented this groundbreaking concept in our previous SA-55M & SA-60M model, now extending it to the RN-55M, thereby revolutionizing the landscape of lightweight sport wheel design. Today, WedsSport continues to leverage this proven design across a range of our models, further solidifying our commitment to engineering excellence and performance innovation.
