Polo Wheels (Tyres, Spokes & Rims)

Butted = swaged

The diameter reduction increases spoke elasticity, increases strength by work hardening, and reduces weight. However, the most valuable contribution of swaging is that peak stresses are absorbed in the straight midsection rather than concentrated in the threads and elbow, thereby substantially reducing fatigue failures. Swaged spokes act like strain screws commonly used in high-performance machinery.
