There are any number of reasons why a cyclist might want a spare Kask Bambino Pro Helmet Visor on hand. Maybe the original was involved in an unfortunate incident deep in the chaotic bowels of the kit bag. Maybe the lighting conditions for a given event require more or less tint. Maybe the reason is aesthetic (gotta match the club colors). Whatever the case, Kask's magnetic visor system makes changing your stripes easy: just clip on the visor, clip into the pedals, and set off.
