Making an early bid for this season's best all-round road helmet, the Specialized Propero has received a total makeover, emerging sleeker and faster than its three previous editions.
Rather than redesigning the Propero update from the ground up, the Propero 4 is, in fact, a mash-up of two all-time favorites. Specialized says it took the aerodynamic qualities of the S-Works Evade 3 and the ventilation characteristics of the latest S-Works Prevail 3 and blended them together to create this all-new Propero.
