Bell Volt Road Helmet. A regular on the Pro Tour, the Volt is an amazing combination of massive ventilation, svelte weight, and high-tech comfort for road or mountain. 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,the system arms are co-molded with soft rubber and positioned them higher to better accommodate eyewear.
