Faster is Cooler.

The Synthe™ is the pinnacle of road helmet design, combining the performance gains of aero efficiency and light weight with great cooling power to enhance rider comfort and efficiency.

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. Our 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 our test results and nearly matching the temperatures recorded for a bare headform over 30 minutes.


The difference is clear in the wind tunnel—our extensive testing reveals that the Synthe is nearly as efficient as the fastest time trial helmets. But the Synthe’s greatest attributes are comfort and ventilation. At it’s heart you’ll find our Roc Loc Air fit system. Micro adjustments allow you to custom tune tension and fore-aft tilt with one hand and a patented design suspends the helmet over the top of the skull, allowing airflow to pass freely over your head. Cooling power is further boosted by elaborate internal channeling and a series of massive vents; the Synthe sets a new bar for ventilation.

You no longer need to choose between aerodynamics and cooling power—with Synthe you get everything, all wrapped up in a compact and sleek silhouette.

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.
