The Details
Safety has been optimised on the Propero 3. A MIPS protection system which provides excellent protection from rotational impacts, whilst an ANGi sensor can be combined with the Specialized Ride app to evaluate the forces acting on your helmet and, when necessary, send a text message to chosen contacts with your location.
The road helmet also features a 4th dimension cooling system with a Mega Mouthport to offer supreme ventilation and keep you cool at all times. At the same time, a Soft 4X DryLite webbing material dries quickly and is highly durable, meaning that you have to worry less about replacing the inner of your helmet.
Specialized made comfort a priority when designing the Propero 3. A Tri-Fix web splitter allows for ease of strap adjustments and excellent comfort, whilst a HairPort FSL II fit system with four height positions and a micro-adjustable dial allows you to tailor the helmet to the perfect fit.
