BELL Avenue MIPS Adult Road Bike Helmet - Matte Green (2023), Small/Medium (50-57 cm)

FUSION IN-MOLDING POLYCARBONATE SHELL - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
INTEGRATED MIPS (MULTI-DIRECTIONAL IMPACT PROTECTION SYSTEM) - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts.
ERGO-FIT LED - What was once ErgoDial now has an improved dial feel and function (no longer requires a push to turn) and is more sleek and less bulky.
NO-TWIST TRI-GLIDES AND SWEAT GUIDE - Quick-adjust fasteners that help keep straps flat and properly positioned. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
SPECIFICATIONS - Universal Women's (50-57 cm), Universal Adult (54-61 cm), and Universal XL (58-63 cm) Sizes.Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous; 16 vents.
