The sleek shape gets plenty of attention but the real story with Sequence is its incredible versatility. With a classic cross-country profile, massive ventilation and superb fit system, you can wear it day in and day out on your trail ride. With its two-way-adjustable TAG Fit System, 24 flow-tuned vents and VPV adjustable visor, Sequence is also perfectly suitable for an all-day epic on the weekend. 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. Specially designed ventilation channels on the interior of the helmet's liner brings cool air in through the front, passes it over the head and flushes warm air out of the rear ports. Bell's top-of-the-line Variable Position Visor allows for 15 degrees of horizontal adjustment by using an imbedded clutch mechanism that holds the visor firmly at the desired angle. Changing the VPV's angle just takes a simple up or down tug.
