Faster is Cooler. Imagine a light weight low-profile helmet with aerodynamic efficiency that rivals a time trial design & 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 Synthes 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 & 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 youre battling for KOMs or a personal best at the summit.
