Key Features

TAG Fit System

Bell Sequence Helmet Twin Axis Gear TAG Fit System
Bell's next-generation Twin Axis Gear™ (TAG) fit system adjusts to the head on two axes - circumferentially as standard fit systems do, but also horizontally to better accommodate differences in the up/down position of the occipital lobe. For added comfort, Bell has co-molded the system arms with soft rubber and positioned them higher to better accommodate eyewear. The result is the most adjustable, comfortable and easy-to-use fit system ever.

Fusion In-Mold Microshell

Bell Sequence Helmet Fusion In-Mold Microshell

The process of bonding the helmet’s microshell to its extruded polystyrene (EPS) foam layer is called In-Molding. The EPS foam is shot into the thin Microshell cap while it is still in the mold, rather than being formed separately and later taped into place; this produces a very solid and sturdy helmet. Pioneered by bell, this method is now industry standard for all high end helmets and is a standard feature on all of Bell’s helmets for adults and children alike.

GPS Fit System

Exclusive to Bell, the Geared Positioning System (GPS) Fit System delivers the ultimate one hand adjustment for superior fit, comfort and a glove like fit. Simply slide the dial to click-in to the perfect custom fit.

Internal Reinforcement

Bell Sequence Helmet Internal Reinforcement

In order to maximize venting and minimize bulk, high-end helmets feature internal reinforcement structures. These composite skeletons fortify helmets the same way re-bar makes concrete stronger, allowing for bigger vents, more advanced styling and lighter weight, while still meeting stringent safety standards.

Channeled Ventilation

Bell Sequence Helmet Channeled Ventilation

Specially designed with 24 flow tuned vents on the interior of the helmet’s liner, the Sequence brings cool air in through the front, allowing it to pass over the head while flushing out the warm air via the rear ports. You will notice an adaptation of this feature on the majority of Bell’s helmets, however the higher end models feature deeply sculpted channels which keep air moving, whether you’re ripping forward at mock speed, or huffing it up hill at a near standstill.

VPV Adjustable Visor

Bell Sequence Helmet Variable Position Visor (VPV)

Bell’s top-of-the-line Variable Position Visor allows for 15 degrees of horizontal adjustment by using an embedded clutch mechanism that holds the visor firmly at the desired angle. Changing the VPV’s angle just takes a simple up or down tug.

Cam-lock Levers

Bell’s easy to adjust Cam-Lock strap levers make adjusting the straps around your ears a snap. Simply open the cam, find a comfortable position and close the lever. That’s it.
