A VERSATILE PERFORMER Whether it’s fitness routes, adventures, or family rides around the neighborhood…with its simple and accessible style, the Trace helmet is a multidisciplinary performer that gives you plenty of versatility and options. The Ergo Fit system offers a slim, easy-to-use dial with the integrated MIPS option. And anti-twist Tri-Glides flat straps provide a precise fit. But we didn't stop there; we wanted to take it a step further by offering an LED version. By incorporating a bright 20-lumen rear LED light into the fit system, which is discreet, highly visible, and easily rechargeable via the included micro-USB, we have ensured you get comfort, style, performance, and visibility for all your rides.
