Giro Synthe Road Bike Helmet
Imagine a light weight, low-profile helmet with aerodynamic efficiency that rivals a time trial design and also provides awesome cooling power. A synthesis of the performance benefits you want, every time you line up to race, train or ride. Now, you can have those benefits in a single helmet, the Synthe™.
The Synthe’s aerodynamic efficiency is a breakthrough in vented helmet design. Giro’s extensive wind tunnel testing, using wind averaged drag calculations to assess performance in a wide range of conditions, reveals that the Synthe is nearly as fast as time trial helmets in a standard “road” position, without compromising the cooling power your body needs for maximum power output. That cooling power is immediately apparent on the road, besting Giros test results and nearly matching the temperatures recorded for a bare headform over 30 minutes.
Even with all of this performance, weight is an impressive 250 grams for a size medium CPSC compliant Synthe, making it a great choice when you’re battling for KOM’s or a personal best at the summit.

“The Synthe is sleek, comfortable, incredibly well ventilated and (apparently) pretty aero too. It’s a big step forward in aero road helmet terms as it makes the genre more accessible to the average rider who’s after comfort and acceptable looks as well as performance. But if this is in you’re price range and you’re after a new top-of-the-line lid, the Synthe covers every base better than any road helmet I’ve ever used.” - Road Cycling UK
These Helmets are certified with a European CE EN1078 standard. This is a European standard and although the helmet is perfectly safe to use, specific countries may have their own certification which is legally required if you intend to wear the helmet recreationally or in a competitive racing environment. If you are unsure, please check your specific country requirements and check with the manufacturer to see if the helmet has received any additional certification.
