The Bell Formula LED Mips Road Helmet helps you stay visible, comfortable and protected; all without sacrificing style. It is widely regarded that increased visibility equates to increased safety. To that end, Bell have taken their classy all-rounder, the Formula helmet, and incorporated a bright, 20-lumen rear LED into the fit system. It’s unobtrusive, highly visible and easily rechargeable with an included micro USB.  Bell Formula LED Mips Road Helmet Features Integrated MIPS (Multi-Directional Impact Protection System) - MIPS is designed to reduce rotational forces that can result from certain impacts. By integrating the MIPS slip plane into the retention system, Bell were able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head. Fusion In-Mold polycarbonate shell - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. Float Fit LED - A lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS). No-Twist Tri-Glides: 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. Rechargeable LED lighted dial - Estimated run times: 2.5 hours steady; 5 hours strobe; 10 hours pulse. Micro USB cord included. CE EN1078 certified.
