It's no secret that an aero helmet saves at least as much time as an aero frame or aero wheels at a much lower expense. We have seen some wind tunnel tests that suggest the savings may be in the area 30 seconds to almost 2 minutes over a 25 miles/40k course. The Bell Javelin helmet seems to us like a more friendly aero helmet because of its excellent fit and features.
Featuring a wind-tunnel and real world-proven aerodynamic fuselage, the Javelin is designed to be both fast and ventilated. Two front intake ports and one rear exhaust port provide some ventilation. Bell's super adjustable Twin Axis gear (TAG) fit system makes fitting easy. The Javelin comfortably slides on with very little effort compared to other aero helmets and the dial fit adjust makes fine tuning a virtual snap. The exclusive SeamFlex ear flaps make getting the Javelin on and off both quick and pain free-a big plus particularly if having a fast and smooth transition area is part of your plans.
The Javelin is extremely comfortable in comparison to other aero helmets that fit tightly and almost have to be wedged on. It sits on the head just where it should the included detachable wind shield in the perfect location.
