After months of teasing and testing with its Trek Factory Racing road team, Bontrager has officially tossed its hat into the aero road helmet arena with the new Ballista. Some might feel that the shape is somewhat derivative but Bontrager says it works, offering wind tunnel-proven aerodynamic benefits plus excellent ventilation.
As with many other aero road helmets, the Ballista sports a trim and tightly fitting profile that tapers down dramatically out back. According to Bontrager, testing at the Low Speed Wind Tunnel in San Diego, California has shown the Ballista to be faster than key competitors such as the Specialized S-Works Evade, Giro Air Attack, and Louis Garneau Course.

Bontrager says its new Ballista is the fastest aero road helmet around
Aero road helmets aren’t solely about going fast, though. If they were, we’d all be racing in full-blown TT lids.
Bontrager says the Ballista is also very well ventilated with three centrally placed vents up front to suck in air plus deep internal channeling and generously sized exhaust ports to help that air pass through unencumbered. There’s plenty of space in between the browpad and forehead as well – an area BikeRadar has found to be critically important not only for keeping your head cool but minimizing the amount of sweat that drips down into your eyes.
