When Specialized Bikes invited TWC down to attend the launch of some new and exciting road cycling kit, we couldn’t have run out the door fast enough. Here are whats hitting the shops right now…
Specialized Evade II Helmet
Lighter, faster and better ventilated – this is EVERYTHING you want from a helmet, right?! Add to that a more sleek appearance and it appears that Specialized are on to a winner with the new Evade II.
The Evade II shares its DNA with Specialized’s S-works TT helmet instead of the original Evade. Also developed using Specialized’s wind tunnel facilities the TT helmet is undoubtedly their most aero to date but given the limited time in the saddle at ‘all-out’ effort ventilation was never a priority. It’s a different story however when it comes to longer stages and both ventilation and wind resistance are vital considerations.
Good ventilation can’t be achieved by simply punching holes into a helmet; the secret is to draw the air in, sweep it over the head and most importantly push the, now, warm air out the back. For this, Specialized has turned to their successful 4th-dimensional cooling system;
– The position of the mouth port drags the air in
– Inline vents maintain the flow of air through the front of the helmet
– Deep channels on the interior surface of the helmet create space to promote the flow of cool air
– Rear vents assist with creating a vacuum effect which draws the air flow through
Specialized applied 12 heat sensors to a manikin; each representing different ‘climate zones’ and the heat production of a given rider, the sensors determined which formation of vents provided a greater cooling efficiency.
From the functional testing method for the Evade II, Specialized shaved off a whopping 16-20 grams (depending on helmet size) even with the inclusion of the magnetic buckle which is heavier than a standard closure.
No doubt the move from single to dual density foam that was first seen through the Prevail series helped as utilising the larger surface area across the top of the helmet to dissipate the forces seen during a crash enabled Specialized to reduce the foam density. In turn, they strengthened the sides of the helmet where curb stone hits are more commonly seen and reinforced the back and front with an internal Aramid roll cage to keep the important stuff like memory and speech safe and sound.
The shorter and narrower appearance of the Evade II is also a result of functional testing and makes it more appealing. The overhangs are smaller and the helmet drops slightly lower over the ears more like a conventional GC helmet than a dedicated aero helmet.
S-Works Evade II is available in 5 colours and sizes Small, Medium and Large
