It is widely regarded that increased visibility equates to increased safety. To that end, we have taken our classy all-rounder, the Formula, and incorporated a bright, 20-lumen rear LED into the fit system. It’s unobtrusive, highly visible, easily rechargeable with an included micro USB, and it just might make the difference between being seen and not. The already impressive performance and value of the Formula shines even brighter with the addition of an integrated LED rear light.
