Aerodynamic, lightweight, durable… There was a time when riders would be faced with choosing between these attributes when selecting wheels. But that time is gone. With 60mm (front) and 66mm (rear) deep rims, bladed spokes (12f/18r) and narrow flange spacing, Mad Fiber Road Wheels and their patent pending technology have been validated in the San Diego low speed wind tunnel as being among the best in the business in terms of aerodynamics, and particularly distinguish themselves from the competition in crosswinds.
