You need some special helmet for time trial races, not the common ones. You need something that guarantees your head will stay fresh and cool despite the entirely blood rushing speed and the intense adrenaline. You need something that does not hinder; instead, it must enhance your movements if possible, with the most minimum wind resistance. And protection can not be neglected since that is the primary role of a helmet. The requirements are many, yet Bell and Giro do not yield. They try to design the perfect bike race helmet within the Javelin and the Selector.
Bell Javelin provides the ultimate aerodynamic performance. Bell Javelin has a special wind-tunnel with channeled ventilation to lessen wind resistance across the helmet, along to give a proper coolness on the user’s head in any condition. Its features Twin Axis Gear fit system is pretty easy to be used and handled, also fit well on the head. Another main feature is its removable race shield. The shield often becomes a significant weight addition in many race helmets, and here you are allowed to wear and unwear the thing according to your needs. Bell Javelin uses X-Static Padding.
With the shield on, Bell Javelin is slightly heavier than Giro Selector. Without the shield, it is slightly lighter. Giro Selector’s shield is unremovable. Anyhow, Giro Selector is armed with its own unique feature: The Selector, hence the name. The Selector is a feature to adjust the tail of the helmet. There are two different lower tail adjusments that you can choose to get the best aerodynamics based on your own posture, riding position, and course conditions. If you believe that every split second counts, then this helmet is perfect for you. Giro Selector has the famous Roc Loc 5 fit system which suits every kind of head and also X-Static Padding. The ventilation system is quite unique here, with the vented eye shield connected with internal vent channels to provide cool air while heated air will be exhausted out from the back tunnels.
