Anti-scratch and UV protected shield for the Star, Vortex, RS-1 and Revolver helmets. 3Mode ShieldTM for instant on-bike shield adjustments, and ClickReleaseTM for the fastest, easiest, tool-free shield swaps ever. Bell's 3Mode Shield allows for one-finger toggling between Lock Mode, Friction Mode and Crack Mode. Lock Mode is the shield's firmest and quietest setting. It not only locks down the shield, but pulls it tightly to the gasket, creating a water-tight seal. The Friction Mode allows the shield to be freely adjusted from fully closed to fully open and anywhere in between. Crack Mode disengages the shield from the gasket and lifts it about ¼" to help prevent fogging, a particularly useful setting at stop lights. A quick touch of the 3Mode Lever brings the shield back into Lock Mode.ClickRelease was designed for the quickest, easiest shield swaps ever. To remove, simply fully open the shield and depress the ClickRelease Triggers. For installation, just align shield pivots in the fully open position and push until they click into place. Done.
