Bontrager Ballista
Cycling Weekly Verdict

The Bontrager Ballista is a pro level aero helmet that performs brilliantly. Although expensive, it is half the price of many other leading brands rival products and we highly recommend it. The only issue is the lack of sunglasses holes.

The Ballista was famously worn by Jens Voigt during his successful tilt at the Hour Record and is worn by the Trek-Segafredo racing team. Bontrager has refined the design in the wind tunnel and having undertaken competitive testing Bontrager claims that the Ballista is more aerodynamic than other leading helmets, such as the Giro Air Attack and Specialized Evade. To date, I haven't had time to carry out my own quantitative testing to back up the claim, but will aim to do this in future.
