Bell Star Wars Segment Bicycle Helmet Darth Vader. If the dark side of the force strikes your fancy then your choice in protective headgear will be a no brainer: the limited edition Bell Segment Star Wars Bicycle Helmet with Darth Vader graphics. The skate style Bicycle Helmet aesthetic never gets old, and Bell has applied their extensive Bicycle Helmet know how for a modern take on the timeless classic. The secret to the Segment's comfort is Bell FormFit which makes the Bicycle Helmet fit more like a comfortable cap than a hard shell Bicycle Helmet. The eight internal segments are connected by a reinforcing skeleton that allows the Bicycle Helmet to flex and conform to the shape of your head. The Segment meets both skate and BMX safety standards, making it the perfect everyday Bicycle Helmet to partake in adventures on a pump track, around town, or galaxies far, far away.
