The Bullet helmet provides an answer to the age-old dilemma of ventilation versus aerodynamics. With its narrow shape and closed shell it is a seriously aerodynamic helmet but a quick adjustment to the Airslide system turns it into a helmet with sufficient ventilation to tackle climbs on hot days.
The Bullet helmet will provide you with a snug fit and a helmet that is well fitting. This in turn creates a narrow shape with a small frontal area, creating the drop like shape of the helmet. In combination with the closed shell, this creates the aerodynamic performance to make the Bullet into a sprint helmet.
When ventilation is required, the Airslide system can be utilized to open up the front of the helmet and create an airflow throughout with exhaust vents at the rear. When ventilation is of lesser importance, the entire Airslide system can be exchanged for a fully closed cap, creating an even more aerodynamic version of the helmet.
On top of this performance the Bullet helmet also allows a quick and easy installation of the LifeBEAM technology to measure your heart rate, or the Inclination Sensor to monitor your head position on the bike.
Fast like a bullet, it's the perfect combination of aerodynamics and ventilation, whenever you need it!
The Advanced Turnfit System / ATS® is a new interpretation of the classic Turnfit system. It combines the traditional Turnfit dial system with the Rollsys head basket to create an even more effective retention system. A dial at the back of the helmet now controls a basket that grips a large part of back of the head. A quick turn of the ATS® dial makes sure the basket grips the back of the head for a snug yet comfortable fit that keeps the helmet firmly in place.
Please measure your head circumference to get the right helmet size.
