Specialized updates Prevail helmet with more aero design

New model retains the gaping front vent of its predecessor

The Specialized Prevail helmet has been around for six years now, and in that time has been ridden to a handful of Grand Tours and numerous stage victories. Now Specialized has released details of a new version, with an updated more aerodynamic design.

Ok, before we get too carried away, it’s not a huge aerodynamic gain. Its creators says that the new Specialized Prevail II helmet will save you 6 seconds per 40km compared to a normal road helmet, so not a lot, but frankly we’ll take ever 6 seconds we can get.

The back of the Specialized Prevail II helmet is designed to let hot air escape

Other than the aerodynamic improvements, the Specialized Prevail II helmet has retained the open front that characterised its predecessor, which is combined with internal channels and rear “exhaust ports” for what we hope will be excellent ventilation.

Adjustment is provided by the Mindset dial adjustment system found many of the company’s other helmets such as the Specialized Evade helmet and Specialized Airnet helmet. This not only provides adjustment to help the helmet fit the circumference of your head, but can also be moved up and down to help you place the helmet casing in a comfortable position.

Finally the Specialized Prevail II helmet is apparently quieter than the competition (i.e. there is less wind noise) and also has reflective decals on the rear for when you’re riding after dark.

Available immediately, the Specialized Prevail II helmet will come in men’s and women’s versions, both in three different sizes and with a few colour options, and is priced at £160.
