Bell Lumen

The Bell Lumen is a low mid-cost bicycle helmet. The GPS fit system of this helmet fits snug, and allows you to simply slide the dial and click-in to adjust sizes. There is a composite skeleton inside the Lumen helmet for internal reinforcement which allows this helmet to stay lightweight (10.7 ounces) while still being safe.

 The Fusion In-Mold Microshell is bonded to the helmet's EPS (Extended PolyStyrene) foam layer, which makes for a sturdier helmet. This helmet is a step down from the higher cost Array helmet in that it is less lightweight (10.7 ounces as opposed to 10), has the GPS fit system as opposed to the TAG fit system, and has fewer color options.
