We cannot deny that we were surprised to hear about Giro’s new Synthe aero road helmet. We typically have a pretty good idea when something’s in the works, but this time Giro caught us by surprise. Not just because we hadn’t seen evidence of a new product, but because they already had an aero road helmet – the Air Attack. But where the Air Attack is a TT helmet for road racing, the Synthe is a true aero road helmet.
The Synthe assumes a more traditional helmet form than the controversial Air Attack design. Designed with 19 vents and an internal channeling for cooling, the Synthe is 2% cooler than the already frosty Aeon.
And while the Air Attack will still beat the Synthe when racing heads down, in a traditional road position (head angle of 30 degrees at a speed of 25mph) the new Synthe is more aerodynamically efficient. Compared to the Aeon, Giro’s more traditional road helmet, the Synthe claims to be 16% faster.
The Synthe weighs in at 250g (CPSC Medium), making the helmet 13% lighter than the Air Attack.
Giro chose to use their Roc Loc fit system, which we’ve enjoyed using with their previous helmets. We’ve found this system to be one of the most comfortable on the market.
One of our favorite features of the Synthe is Giro’s decision to build in a specific spot to place your glasses. Giro calls them “eyewear docking ports” – we call just them smart.
For those looking for free speed in the peloton, this is a helmet you should keep an eye on. It should be available in the fall at an expected MSRP of $250. We plan on getting some time with the Synthe before then—bringing along our trusty Air Attack for a comparison. Stay tuned!
